The WEH® quick coupling  FI  reliably and quickly seals inside bores, irregular or rough holes and internally threaded components. Fitted with elastomer seals ideal for sealing out of round and rough surfaces and clearing large tolerances on the test piece. The connector‘s only means of clamping into the test piece is frictional between seal and surface therefore a fixture must be used.
Because of the pneumatic actuation, the type FI is particularly well suited for automation of test procedures.
Special versions, e.g. twin connectors for sealing ports in close proximity to each other are available on request. Shaft extensions or shortenings for FI connectors are also available.
