Types of Gaskets for Commercial Refrigeration Explained: Snap-In, Screw-In, Push-In, Compression, Panel, & Glass Door

With multiple types of gaskets for commercial refrigeration available, do you know which one your model requires? There are several gasket types (profiles) designed to fit specific OEM models and door configurations. If you select the wrong gasket profile for your model, it won’t seal the unit’s doors properly—risking heat leakage and other performance issues.

Learn more about the different types of gaskets in commercial refrigeration, their differences, and where they’re often used to help you find the right replacement parts.

What is a Commercial Refrigeration Door Gasket Profile?

A gasket profile is the industry term used to identify a type of gasket. It’s categorized by physical shape and how it’s installed onto the door. OEMs design specific gasket profiles for different refrigeration models to ensure a secure fit and proper sealing.

How Do I Know Which Gasket Profile My Model Needs?

You can find your model’s required gasket profile on the door ID tag or the operation manual. Depending on the model, door ID tags are often located on the outer edge of the door frame.

In many cases, a gasket distributor can also help you identify the correct profile using the OEM model number and serial number. This information is also found on the door ID tag, even if you don’t know the gasket profile yourself. 

If your door ID tag is unreadable or missing, photos of the existing gasket and unit door dimensions can help a gasket distributor determine the proper replacement part.

Understanding the Different Types of Gaskets for Commercial Refrigeration

Below are the most common gasket types (profiles) used for commercial refrigeration and how they support your unit’s functionality.

Compression Gaskets

A compression gasket looks like a narrow half-circle that installs into refrigeration doors using compressed pressure. Because compression gaskets don’t typically have magnetic elements, they’re often paired with mechanical latch-and-strike systems to help seal the doors closed.

They come in different shapes and are manufactured with either PVC or Santoprene® for durability and wide temperature resistance. 

Compression gaskets are commonly found on:

• Refrigeration drawers

• Older refrigeration units

• Specialty refrigeration systems with latch-style doors

Glass Door Gaskets

A glass door gasket has different wrap-around shapes designed specifically for refrigeration with glass doors. The installation process involves molding around the glass edge to help protect the door from shattering when opening and closing. They’re often manufactured with Santoprene® or PVC (vinyl).

Glass door gaskets are commonly used on:

• Supermarket and retail refrigerated display cases

• Convenience store beverage coolers

• Glass door merchandisers  

Panel Gaskets

A panel gasket has a T-letter shape that integrates with decorative refrigerator panels. They help protect the surrounding panel surfaces while maintaining proper door operation. 

Many built-in refrigeration systems use panel gaskets to create a finished cabinet-style appearance around a commercial refrigeration unit. They can be manufactured from various gasket materials, including PVC, silicone, and thermoplastic rubbers (TPE).

Panel gaskets are commonly used on:

• Commercial kitchens with custom cabinetry

• Hotel kitchen refrigerators with decorative built-in cabinetry

• Custom walk-in cooler and cold storage panel systems 

Push-In Gaskets

A push-in gasket has a rectangular or square-shaped dart that’s installed by pushing directly into the refrigeration door’s grooved channel. They can be manufactured from various materials, including synthetic rubber (EPDM) and PVC. Many also have magnetic strips to create a stronger seal.

Although push-in gaskets look similar to snap-in profiles, they use a different attachment design and aren’t interchangeable. 

Push-in gaskets are commonly used on:

• Restaurant walk-in refrigerators

• Foodservice refrigeration equipment

• Refrigerated warehouses and food processing facilities

• Industrial refrigeration systems

Snap-In Gaskets

A snap-in gasket has a triangular or arrow-shaped dart base that snaps into a slot in the retainer strip on your unit’s door frame. It’s one of the most popular profiles for solid-style refrigeration doors. They’re often manufactured with PVC and Santoprene® due to their durability and temperature flexibility in commercial refrigeration environments.

Snap-in gaskets are commonly found on:

• Medical vaccine storage units and laboratory refrigeration equipment

• Hospitality banquet kitchen walk-in coolers

• Foodservice walk-in freezers

Screw-In Gaskets

A screw-in gasket has a rectangular top that attaches directly to the refrigeration door using stainless steel screws to secure the gasket’s lower lip. Many also have magnetic elements to maintain an airtight seal. These gasket profiles are often manufactured using PVC and Santoprene® materials.

Screw-in gaskets are commonly found on:

• Restaurant under-counter refrigeration equipment

• Foodservice reach-in refrigerators 

• Chef base refrigeration units

Key Facts About Commercial Refrigeration Door Gasket Profiles

• Commercial refrigeration door gasket profiles refer to their shape and how they’re installed

• All gasket profiles are model-specific, with unique installation methods, and aren’t interchangeable

• The main gasket profiles are compression, glass door, panel, push-in, snap-in, and screw-in 

• The OEM model number and serial number found on your unit’s door ID tag or operation manual can identify the correct gasket profile
