Rubber Extrusions and Rubber Seals

About Extruded Rubber Seals

What is a rubber profile? Rubber extrusions are parts that are run through an extruder or extrusion machine and forced through a die to manufacture the necessary cross section (or extruded rubber shape), such as squares, cord shapes, and hollow sections. Cross and hollow sections add compression for sealing.

Rubber Seal Applications

Trim-Lok’s extruded rubber profiles are used for many functions, including:

  • Windowpanes
  • Garage doors
  • Vehicle sunroofs
  • Windshields
  • Tonneau covers
  • Boat hatches
  • Other home and vehicle applications

At Trim-Lok, many of our sealing rubber parts are made from a custom- formulated EPDM sponge rubber that protects against extreme weather, drowns out noise, and eliminates vibration. Our rubber shapes are an ideal solution for your rubber extrusion and sealing needs—whether your application is automotive, marine or within another of our supported industries.
