The CERROBRASS 301-88 is a barbed push-on hose male connector designed for secure, leak-resistant hose-to-pipe connections in fluid-handling systems. Machined from brass, this fitting features a 1/2 inch NPTF threaded male end and a 1/2 inch barb end that grips push-on hose without the need for clamps in low-stress applications. The NPTF thread form creates a pressure-tight seal through thread deformation, reducing reliance on tape or sealant. Rated to 300 psi maximum working pressure, it handles temperatures from -40 degrees F to 212 degrees F, making it suitable for water, air, and compatible fluid lines in both stationary and mobile equipment.
This connector is used in plumbing, HVAC, pneumatic, and hydraulic hose assemblies where a threaded pipe connection transitions to a barbed hose end. Typical applications include residential and light commercial water distribution, compressed-air lines, and equipment plumbing where a reliable push-on barb-to-NPT male transition is needed. Plumbers, pipefitters, and equipment technicians install this fitting in situations requiring a compact, metal fitting that can handle moderate pressure and a wide service temperature range.
Designed as an OEM-style replacement or new-installation fitting for 1/2 inch inside diameter push-on hose systems requiring a 1/2 inch NPTF male threaded port connection.
Installation should be performed by a qualified plumber or pipefitter following applicable IPC and local plumbing code requirements. Shut off and depressurize the system before removing or installing any fitting. NPTF threads are designed to seal on the threads themselves, but thread sealant or tape may be applied per job specifications. Push the hose fully onto the barb until seated against the fitting shoulder, and confirm hose security before returning the system to service.
