Low Torque AV Gaskets (1/2" – 12")
Asahi valve gaskets offer a unique double convex ring design that gives optimum sealing with only 1/3 the torque commonly required with flat faced gaskets. Asahi/America offers EPDM gaskets from 1/2" to 12"; PTFE-bonded EPDM gaskets in sizes from 1/2" to 12"; and PVDF-bonded EPDM gaskets from 1/2" to 10".
AV low torque gaskets provide a bubble tight seal for flanged valve and piping connections. They feature a small bolt torque requirement for ease of installation and for accommodating a variety of thermoplastic valves, piping and fittings. All styles include two molded concentric sealing rings for confident sealing abilities. The sulfur-cured rubber is made to fit with flat faced flanges and is available with either a PVDF or PTFE laminated sealing surface for aggressive chemical or high purity installations.
Backing Rings (1/2" – 12" - Euro Grey 1/2"-24" - Black)
Flange connections are an essential part of every piping system. For detachable connections to butterfly valves or transitions to other materials, Asahi/America’s backing rings, installed with plastic stub end flanges, are the ideal solution to provide a force-locking connection offering superior safety for any system.
