Weatherstrips increase the life of window frames by offering protection against weather elements. In vehicles, they dampen vibrations for a more comfortable experience. CRL's rubber weatherstrips are as DIY as they can get, allowing you to fabricate your own windows.

The weatherstrips are extruded in a number of sizes, and available in one-piece and two-piece designs. They fit glass panel thicknesses from 1/8'' to 1/4'', and body panel thicknesses from 1/32'' to 25/32''.

Applications of CRL self-sealing weatherstrip

  • Windows in sound booths, sandblasting booths and other enclosures that require a flat surface window.
  • As a windshield seal on big rig tractors, the weatherstrips can be installed quickly and easily on new or re-glazed windows.
  • Vans, campers and recreational vehicles; these weatherstrips meet federal push-out requirements.
  • CRL weatherstrip can be used to add new windows to construction vehicles or re-glaze broken ones.
  • Portholes and cabin windows; CRL weatherstrip is designed to weather rough marine conditions, and can accommodate radiuses as small as 1-1/4''.


One-piece and two-piece self-sealing weatherstrips

One Piece

CRL's one-piece self-sealing weatherstrips are ideal for use on older trucks, off-road construction equipment, or farm equipment. As they are available in a range of sizes, finding the right one is easy but your gasket set installation can also be timely and efficient.

The weatherstrips are made from EPDM anti-oxidizing black rubber, which is known for its tear, weather and stain resistant qualities. EPDM is highly resistant to degradation by UV radiation, as well as high and low temperature extremes.

A best-seller is the AS987 weatherstrip for 3/32'' to 9/64'' panel or 3/16'' to ¼'' glass.

Two Piece

Like the one-piece weatherstrips, CRL's two-piece weatherstrips have multiple applications and offer a tight-fitting seal. The AS937 3/8'' wide locking strip is easy-to-use and available in chrome and black.
