Notes
Multiple configuration variants combine 3/8\" (10 mm) and 9/16\" (14.3 mm) couplings with different thread standards (UN/UNF/UNS and ORFS/ORB) to match market-driven interchange standards. Electrical contact options are available on some male configurations. Item weights and number of housings/couplings vary by model.
