Parker X1/8F3HG-B Pipe Adapter 1/8 in Mbspt X Fnptf Brass

Product Description

The PARKER X1/8F3HG-B is a brass pipe adapter designed to connect male BSPT (British Standard Pipe Taper) threads to female NPT female threads in industrial fluid systems. The adapter handles a maximum working pressure of 1000 psi and operates across a wide temperature range, from -40 degrees F to 302 degrees F. At 0.04 pounds, it is a compact, single-piece fitting suited for use in pneumatic, hydraulic, and general-purpose fluid lines. Licensed plumbers, pipefitters, and HVAC technicians install this type of adapter when converting between BSP and NPT thread standards at 1/8 inch connections.

This adapter is used wherever a 1/8 inch MBSPT male thread must mate with a 1/8 inch FNPTF female port. Common applications include compressed air lines, hydraulic circuits, instrumentation taps, and light industrial fluid systems. Its brass construction offers corrosion resistance in moderate-duty service environments, making it a practical choice for both residential mechanical rooms and commercial plant installations.

Installation Notes

This fitting is installed by licensed plumbers or pipefitters working on pressurized fluid or air systems. Shut down and depressurize the system completely before removing or installing any threaded fittings. Use a calibrated torque wrench and apply appropriate thread sealant compatible with the system fluid — do not use PTFE tape on BSP taper threads without verifying suitability. Adhere to applicable plumbing and mechanical codes, including IPC and ASME B1.20.1, for threaded pipe joint assembly.
