Cerrobrass 103A-A Pipe Coupling 1/8 in Fnptf 1200 Psi

Product Description

The CERROBRASS 103A-A is a female-threaded pipe coupling designed for industrial plumbing and fluid system applications. It features a 1/8 inch FNPTF (Female National Pipe Taper Fuel) thread on both ends and is rated to a maximum working pressure of 1,200 psi. This coupling joins two sections of threaded pipe or fittings in a straight-line configuration. It is well suited for compressed air, hydraulic, fuel, and general-purpose fluid lines where a reliable, leak-resistant threaded connection is required. Licensed plumbers, pipefitters, and industrial maintenance technicians are the primary installers.

This coupling is intended for use in industrial piping systems requiring a small-diameter, high-pressure threaded connection. The 1/8 inch thread size fits common instrument ports, pressure gauge connections, and branch lines in both commercial and industrial settings. Its compact size and high pressure rating make it appropriate for hydraulic panels, pneumatic control systems, and fuel delivery lines where fitting integrity under sustained pressure is critical.

Key Features

• 1/8 inch FNPTF thread on both ends for a pressure-tight, tapered fuel-thread connection
• Maximum working pressure of 1,200 psi suitable for hydraulic and pneumatic service
• Straight coupling design joins two threaded pipe segments in line
• Compact form factor fits tight instrument and gauge port locations
• UNSPSC classified under 40175305 for standardized procurement and cataloging

Compatibility

Designed as an OEM-style replacement or new-installation fitting for industrial piping systems using 1/8 inch NPTF threaded connections.

Installation Notes

Installation should be performed by a licensed plumber or qualified pipefitter in accordance with applicable codes such as the IPC or relevant industrial piping standards. Depressurize and isolate the system completely before removing or installing any threaded fittings. Apply an appropriate thread sealant or PTFE tape rated for the service fluid before threading the coupling into place. Do not over-tighten, as this can crack the fitting body or damage the seat of the mating port.
