Northern California's Commercial Refrigeration Gasket Specialists
Commercial Refrigeration Gaskets — Custom-Made for Every Unit, Installed by Certified Technicians
From True reach-ins to Traulsen institutional units to walk-in coolers without a brand name — Cal Gaskets fabricates and installs the right commercial refrigeration gasket for your equipment, on-site, across Northern California.
What Are Commercial Refrigeration Gaskets — and Why Do They Fail?
A commercial refrigeration door gasket is the flexible seal that runs around the perimeter of a refrigerator or freezer door. Its job is simple: keep cold air in and warm air out. When it works correctly, your compressor cycles normally, your interior temperature stays consistent, and your energy bills reflect a well-running system.
When it fails — through cracking, tearing, stiffening, or losing its compression — warm air infiltrates constantly. Your compressor compensates by running harder and longer. Temperatures fluctuate. Food safety risk increases. Health inspectors take note. And eventually, a compressor that should last 10–15 years starts showing early wear.
The failure is usually gradual. Corner cracks appear first. Then the gasket loses its magnetic grip. Then a gap opens along one side. Most operators don't notice until an inspector flags it — or until an energy audit reveals a compressor that's running 20% more than it should.
Cal Gaskets is a hyper-specialized commercial refrigeration gasket company serving Northern California. Gaskets and strip curtains are all we do — which means our product knowledge, fabrication precision, and installation quality go significantly deeper than what a general refrigeration or maintenance company can offer.
What We Replace
Every Type of Commercial Refrigeration Gasket
Walk-in coolers, reach-ins, display cases, prep tables — we fabricate and install gaskets for the full range of commercial refrigeration equipment.
Walk-In Cooler Gaskets
The most critical seal in any food service operation. Walk-in cooler door gaskets take constant traffic, temperature swings, and cleaning chemical exposure. When they fail, warm air infiltration forces your compressor to run continuously — driving energy costs up and shortening equipment life.
Walk-In Cooler Gasket Details →Walk-In Freezer Gaskets
Freezer gaskets operate under more stress than cooler gaskets — sub-zero temperatures cause PVC to contract and stiffen over time. An improper or worn freezer gasket leads to frost buildup around the door frame, ice accumulation on the floor, and a compressor that never cycles off.
Reach-In Cooler & Freezer Gaskets
Reach-in units in prep lines, back-of-house storage areas, and front-of-house display coolers get opened dozens or hundreds of times per shift. The gasket wears from repetitive use, often showing cracks at the corners first. We replace reach-in gaskets for single-door and multi-door configurations across all major brands.
Refrigerated Display Case Gaskets
Grocery store reach-in and open-front display cases have long continuous gasket runs that must maintain a precise fit across the entire door perimeter. A compromised display case seal raises case temperatures, affects product presentation, and triggers health inspection concerns.
Prep Table & Undercounter Gaskets
Refrigerated prep tables and undercounter units are workhorses in commercial kitchens. Their gaskets are often overlooked until a technician points them out on an inspection. We custom-cut replacement gaskets for drawer units, slide-out shelves, and non-standard configurations.
Custom & Discontinued Unit Gaskets
Older walk-in coolers, discontinued models, and non-standard configurations are no problem. Because we custom-fabricate every gasket from commercial-grade PVC material — rather than stocking pre-made sizes — we can produce a proper seal for virtually any unit.
Brands We Service
Gasket Replacement for True, Turbo Air, Traulsen & All Major Brands
Because we custom-fabricate every gasket to your unit's exact specifications, we can service any brand — including older or discontinued models.
True Gasket Replacement
True Manufacturing is the most widely deployed commercial refrigerator brand in North American food service. We replace True T-series, GDM display case, and prep table gaskets regularly across Northern California.
Turbo Air Gasket Replacement
Turbo Air reach-in and under-counter units are common in restaurant prep lines and hotel kitchens. Their gaskets use a specific profile that requires precise corner fabrication — we stock the right material and cut to spec.
Traulsen Gasket Replacement
Traulsen units are built for longevity and found in institutional kitchens, hospital cafeterias, and high-volume food service operations. Their door gaskets are durable but do wear — especially on units with high daily door-cycle counts.
Hussmann Gasket Replacement
Hussmann open-deck and reach-in display cases are standard in grocery stores across the Bay Area. Their continuous gasket runs require precise measurement and seamless corner joins to maintain the seal across the full door perimeter.
Beverage-Air Gasket Replacement
Beverage-Air refrigeration units are common in bars, restaurants, and convenience stores. We replace door gaskets on their reach-in, undercounter, and sandwich prep configurations.
Arctic Air Gasket Replacement
Arctic Air units are frequently found in smaller restaurants and independent food service operations. Their gaskets wear similarly to other brands — corners crack first, then the door seal loses integrity along the edges.
Delfield Gasket Replacement
Delfield sandwich prep tables, reach-ins, and undercounters are a staple of commercial kitchens. We fabricate replacement gaskets to fit Delfield's specific door profiles and deliver a clean, tight seal.
Hoshizaki Gasket Replacement
Hoshizaki reach-in and undercounter refrigeration units are built to precise tolerances. Their gasket replacement requires matching the correct profile — we've done enough Hoshizaki units to know what works.

Know the Signs
8 Signs Your Commercial Refrigeration Gasket Needs Replacing
Most gasket failures develop gradually. By the time a problem is obvious, energy waste has already been accumulating for weeks or months. These are the signs to watch for — and our free inspection will catch any you've missed.
Visible cracks, tears, or gaps anywhere along the gasket perimeter
Condensation or moisture forming around the door frame
Frost or ice buildup on or around the door seal
A piece of paper slides out without resistance when placed between the gasket and frame
The compressor runs more frequently or never fully cycles off
Interior temperatures are higher than your set point despite normal ambient conditions
The door doesn't close firmly or requires force to stay shut
Your energy bills have increased without an obvious explanation
How It Works
Our Commercial Refrigeration Gasket Replacement Process
Free On-Site Inspection
We come to your location, assess every gasket in your facility, and document the condition of each seal with photos. You get a clear report and a recommended action plan at no charge.
Custom Fabrication
We measure each door precisely and fabricate replacement gaskets to the exact dimensions of your unit — not a generic size forced to fit. Commercial-grade PVC material, correct profile for your brand and model.
Certified Installation
Our certified technicians install every gasket correctly and completely — checking door alignment, frame condition, and closure system before and after. No shortcuts, no 'good enough.'
Final Verification
We test the seal on every door before we leave. You get confirmation that the installation is airtight and the door closes and latches correctly.

PVC Strip Curtains — the Other Half of a Sealed Operation
A tight door gasket and a properly installed strip curtain work together. If your walk-in cooler doorway doesn't have strip curtains — or they're worn and gapped — you're losing cold air every time the door opens. We custom-cut and install 8" ribbed PVC strip curtains across Northern California.

Common Questions
Commercial Refrigeration Gasket FAQs
How do I know which gasket profile fits my True refrigerator?
True uses several different gasket profiles depending on the model series — T-series reach-ins, GDM display cases, and prep tables all have different door configurations. We identify the correct profile during our on-site inspection by measuring the door groove and cross-referencing the unit model. You don't need to know the spec — we figure that out.
Can you replace gaskets on older Traulsen units that are no longer in production?
Yes. Traulsen units are built to last decades, and older models are common in institutional kitchens across Northern California. Because we custom-fabricate gaskets from commercial-grade PVC material, we can produce the correct profile for discontinued Traulsen configurations — no generic substitutes.
My Turbo Air reach-in has cracks at the corners — is that the whole gasket or just the corners?
Corner cracking is the most common failure point on reach-in gaskets, including Turbo Air models. In some cases we can address just the corners; in most cases, replacing the full gasket is the right call — a gasket with cracked corners is usually near end-of-life along the full perimeter. We'll assess it on-site and give you an honest recommendation.
Do you replace gaskets on refrigerated display cases for grocery stores?
Yes. We regularly service Hussmann, Tyler, and other display case brands for grocery stores across the Bay Area and Northern California. Display case gaskets require precise measurement and clean corner joins to maintain an unbroken seal — we fabricate them to spec and install on-site.
What's the difference between a refrigerator gasket and a freezer gasket?
Freezer gaskets are fabricated from a PVC compound rated for sub-zero temperatures — the material stays flexible at lower temperatures and doesn't crack or stiffen the way a standard cooler gasket would. Using a cooler gasket on a freezer unit is a common mistake that leads to early failure. We use the correct material for each application.
Can you replace gaskets on Chase doors in grocery stores?
Yes. Chase doors — the heavy swinging doors between the sales floor and conditioned back rooms — carry both perimeter gaskets and top seals that wear down fast. We replace Chase door gaskets and top seals, inspect door alignment and hardware, and document the work so you have a record for your next audit.
