Gas-tight couplings

Gas-tight threaded couplings are used with Ø 15 mm or 22 mm wells, when the immersion depth has to be adjusted on thread installation. Gas-tight couplings have fluoropolymer-ferrules inside. By screwing the cap down, the ferrule is pressed on the well. This connection is gas-tight, but not pressure resistant. Gas-tight threaded couplings available are:

Product number	Type - thread - inner diameter
917347	Gas-tight threaded coupling G1”-15mm
999562	Gas-tight threaded coupling G1”-22mm
