Check Valve



Centek’s line of exhaust systems fittings are made of the same fiberglass and fire retardant resins used to produce Vernatube, the UL listed tubing line. These fittings are lightweight, strong, non-corroding, and durable. Fittings are installed easily and their outside dimensions are compatible with tubing and approved marine rubber exhaust hoses.
