Polyurethane & Rubber Coated Test Gaskets

Hi-Tech Seals manufactures urethane ring type joint gaskets (RTJU) from our BoKure™ urethane MU90 compound. MU90 RTJUs are an effective and non-damaging method of testing your application gland before use. The unique shaped profile energizes the seal in the groove under pressure, replicating a stainless-steel R, RX or BX ring joint gasket. Hi-Tech Seals’ urethane test gaskets can last up to 100 test runs at 15,000 PSI.

Rubber Coated Test Gasket

Rubber coated ring joint test gaskets are used to test flanges before service. The rubber coating avoids potentially damaging metal-to-metal contact. Rubber coated test gaskets are an economical option over the polyurethane test gaskets. With proper handling, rubber coated test gaskets can be used in several tests.
