Parker X3/8F3HG-B Pipe Adapter 3/8 in Mbspt X Fnptf Brass

Product Description

The PARKER X3/8F3HG-B is a brass pipe thread adapter designed to connect male BSPT (British Standard Pipe Taper) external threads to female NPTF (National Pipe Taper Fuel) internal threads in a single compact fitting. Rated to 1000 psi, it handles demanding fluid and gas line applications in industrial and mechanical systems. The 3/8 inch male BSPT thread mates to metric or international-standard piping, while the 3/8 inch female NPTF port accepts standard North American pipe connections. At 1-3/8 inches overall length and a 7/8 inch hex, it fits standard wrenches for secure installation. Fabricated from brass, the fitting resists corrosion across a wide range of media.

This adapter is suited for industrial plumbing, hydraulic, pneumatic, and fluid-transfer systems where international and domestic pipe standards must interface. Typical applications include equipment retrofits, machinery plumbing, and instrumentation lines where BSPT to NPTF thread conversion is required. Plumbers, pipefitters, and industrial maintenance technicians install this fitting in both light manufacturing and heavy process environments. Its compact size and single-piece brass construction make it a straightforward solution for cross-standard thread transitions.

Key Features

• MBSPT x FNPTF thread configuration bridges international and North American pipe standards
• 1000 psi pressure rating suits a wide range of fluid and gas service applications
• Brass construction provides corrosion resistance and compatibility with common process media
• 3/8 inch male and 3/8 inch female thread sizes on a single adapter body
• 7/8 inch hex allows installation with standard open-end or adjustable wrenches
• 1-3/8 inch overall length keeps installation footprint compact

Compatibility

Designed as an OEM-style pipe thread adapter for systems requiring a 3/8 inch MBSPT to 3/8 inch FNPTF thread conversion in brass.

Installation Notes

Installation should be performed by a qualified plumber or pipefitter following applicable codes such as the IPC or relevant ASME B1 thread standards. Shut off and depressurize the system fully before removing or installing any threaded pipe fittings. Apply appropriate thread sealant or PTFE tape to the male BSPT threads per the system fluid compatibility requirements. Do not overtighten; use the hex flats and a properly sized wrench to achieve a leak-free joint without stressing the fitting body.
