The NORGREN C01881038 is a brass push-to-connect swivel Y adapter fitting designed for compressed air and general-purpose pneumatic plumbing lines. It connects a tube-to-male-to-tube-to-male configuration using a BSPT threaded port, allowing a single male BSPT connection to split into two tube runs or consolidate two tube lines into one threaded outlet. The push-to-connect ends simplify assembly and reduce installation time in tight panel or manifold installations. Rated to 150 psi maximum working pressure, this fitting handles typical shop-air and instrumentation-grade pneumatic service. The nitrile O-ring seals support a working temperature range from 0 degrees F to 175 degrees F.
This fitting is suited for residential and light commercial pneumatic systems, compressed air distribution panels, and general-purpose fluid conveyance applications where a reliable branch connection is needed at a BSPT threaded port. The 10 mm outside-diameter tube compatibility makes it a common choice in metric-tubing pneumatic circuits found in HVAC controls, automation panels, and instrumentation setups. Licensed pipefitters and pneumatic system technicians typically install this fitting during system build-out or service.
Designed for general-purpose pneumatic and fluid conveyance systems using 10 mm outside-diameter tubing and BSPT threaded connections.
Depressurize the pneumatic system fully before removing or installing any push-to-connect fittings. Confirm that the mating BSPT port thread form matches before applying torque to avoid cross-threading. Seat the tube to the full insertion depth marked on the tube until it clicks; verify retention by pulling back gently on the tube. Follow applicable plumbing and pneumatic codes for the jurisdiction where the fitting is installed.
