The CERROBRASS 103A-C is a brass pipe coupling with 3/8 inch female National Pipe Taper Fuel (NPTF) threads on both ends. Rated to 1,200 psi maximum working pressure, it is designed for high-integrity fluid and gas connections in demanding industrial and mechanical systems. The FNPTF thread form creates a pressure-tight seal through thread interference, reducing dependence on sealant tape or compound. Plumbers, pipefitters, and mechanical contractors install this fitting wherever a straight inline connection between two threaded pipe runs is required.
This coupling is suited for use in compressed air, hydraulic, fuel, and water supply lines where a durable, leak-resistant threaded connection is needed. Its all-brass construction handles moderate corrosion exposure and is compatible with a wide range of media carried in industrial and commercial piping systems. The compact form factor is practical in tight mechanical spaces where fitting bulk is a concern.
Designed as an OEM-style replacement or new-installation fitting for 3/8 inch NPTF-threaded pipe systems in industrial, commercial, and mechanical plumbing applications.
Installation is performed by licensed plumbers or pipefitters in accordance with applicable mechanical and plumbing codes. Depressurize and drain the affected line segment before removing or installing any fitting. FNPTF threads are designed to seal on thread engagement; inspect threads for damage before assembly and apply thread sealant per job specifications if required. Do not overtighten, as brass fittings are susceptible to thread damage under excessive torque.
