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 Teflon® 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|
