The ANVER Captured O-Ring Barbed Fitting combines the reliable mechanical fit of a metal-to-metal connection with the static sealing qualities of an O-ring to create a leak-proof seal. Designed to screw into suspensions and retain its position, even under constant vibration, it has a machined groove for the O-ring which will not break and flare out when tightened.

Available in 10-32 UNF through 1/8" thread sizes, the ANVER Captured O-Ring Barbed Fitting features a Buna-N O-Ring, and the grooved design simplifies installation by eliminating the need for replacement gaskets or washers because the seal is already properly positioned to create a tight fit. A wide variety of suspensions and vacuum cup types and materials are offered.
