HVAC rubber pipe seals for ceiling ventilation ducts

Trims & Seals for the HVAC Industry

Rooftop HVAC system requires heat resistant seals

Looking for heat resistant seals for a furnace or edge guards for an HVAC replacement part? Explore Trim-Lok’s trims and seals for damper blades, access doors, vibration control and more.

HVAC Seals & Gaskets

The right HVAC gasket or seal can easily complete your repair or replacement project. Our engineers know this, which is why we listen closely to your desired application and work to provide a custom edge trim or trim seal solution for your design.

Trim-Lok offers heat resistant seals and trims for HVAC replacement parts to:

  • • Seal panel openings, flaps and doors
  • • Reduce motor transmission or fan vibration
  • • Allow for thermal expansion and contraction
  • • Protect outdoor applications from UV light, moisture and low temperatures

Applications for Heat Resistant Seals

In addition to our edge trims and trim seals, customers commonly use our rubber seals (X2828, X109BT, X119HT), dual durometer trim, and flap seals for HVAC projects.

Round EPDM rubber gasket for HVAC application, window seals and doors

Common applications include:

  • • Damper blade seals
  • • Access door gaskets
  • • Screw cover gaskets
  • • Duct/rubber pipe seals
  • • Weather stripping
  • • Edge guards
  • • Vibration control
  • • HVAC gaskets

What Is an EPDM Rubber Gasket Used For?

EPDM rubber gaskets and seals are used for sealing environments from ozone, oxygen, acids, weather, sunlight and aging. EPDM rubber provides excellent stability and heat resistance. These properties make it an ideal choice for the HVAC industry.

Heat-Resistant Seal Materials

The combination of materials and adhesives are key to a gasket’s success in its application. We offer custom material selection and design assistance to ensure you get the best possible solution for your application. For HVAC applications, we may use flexible PVC trim, EPDM sponge rubber compound or a combination of materials, such as silicone, polypropylene and TPV.

We assist with material selection by evaluating your HVAC application requirements and material properties such as tensile strength, compression set. We also choose the material based on resistance to heat, abrasion, erosion and flame. Learn more about our materials.

HVAC Seal Secondary Operations

A variety of secondary operations complement our custom design and manufacturing processes for rubber pipe seals, HVAC gaskets, heat resistant seals and trims for HVAC replacement parts. We offer the following secondary operations:

  • • Cut to length
  • • Frame assemblies
  • • O-ring assemblies
  • • Notching
  • • Slip coating
  • • Drilling/notching
  • • Tape discussion*

*If your application requires fastening, pressure-sensitive tape can eliminate the need for screws or other fastening methods such as clips. Contact us to learn how we can help you meet pricing and application goals for your HVAC project.
