113 Series EPDM Ribbed Seal, Rectangular Rubber Seal

Trim-Lok’s Rubber Seals come in a variety of specially designed shapes made from custom-formulated EPDM sponge rubber compound. The Series 113 ribbed seal measures .187” (h) by .375” (w) and offers excellent protection against moisture through specially designed ribs that wick away water and flex with the substrate as it moves.

While this EPDM rubber seal can be used for a number of unique applications, it is commonly used by customers in the automotive and marine industries for sealing and providing a finished edge, as well as by customers in the power generation industry to provide a secure seal on electrical boxes.

Since 1971, Trim-Lok has been providing EPDM ribbed seals, gaskets, and EPDM rubber profiles to the marine, automotive, industrial, and manufacturing industries. Our flexible approach and dedication to quality truly sets us apart from our competitors, and our team has decades of combined experience providing custom trims and seals to fit unique applications.

• "BT" Pressure-Sensitive Adhesive: The 3M Bonded Tape System enables you to achieve the ultimate bond to the rubber and the ultimate bond to the substrate. This tape option creates a moisture barrier and air-tight seal. With the highest peel-and-sheer resistance, the 3M Bonded Tape System can be used under high loads of stress and force. It has low initial tack for easy repositioning during installation and needs 72 hours of cure time to come to full-bond strength. It is rated for good heat performance between -20°F to 158°F.

• "HT" Pressure-Sensitive Adhesive: The Standard Pressure-Sensitive Adhesive option for your seal is an acrylic-based adhesive. It works best when used to hold the seal in place while installing in a static application or when it’s compressed between two stationary objects. It may be used in some light-duty dynamic applications against a variety of substrates. It is rated for good heat performance between -20°F to 158°F. Please note: During installation, ambient temperature must be above 60°F.
