Customize Your Product:

This ribbed-style EPDM sponge rubber seal has a height of .375" and a width of .625". Our ribbed seal is made from a custom-formulated EPDM sponge rubber that protects against extreme weather, drowns out noise, and eliminates vibration.

Trim-Lok ribbed seals create a watertight seal and a finished edge. Rubber profiles are the best choice for sealing and can be used in the automotive, construction, and marine industries in addition to being used as self-adhesive door seals and furniture edgings.

We manufacture this rubber seal with two tape options: BT tape and HT tape. Choose the adhesive that will work best for your situation in the drop-down menu on the right. If you don’t require a self-adhesive rubber seal, choose “no tape.”

Logo for BT self-adhesive for rubber seals and trims3M™ BONDED TAPE SYSTEM 
BT offers the ultimate bond to the rubber and the ultimate bond to the substrate. It creates a moisture barrier and air-tight seal between rubber and substrate. With the highest peel-and-shear resistance, it can be used under high loads of stress and force. It has low initial tack for easy re-positioning during installation and needs 72 hours of cure time to reach full-bond strength. It has good heat performance from -20F to +158F.
