Parker X1/8FHG4-B Pipe Adapter 1000 Psi 1/8 Inch Brass

Product Description

The PARKER X1/8FHG4-B is a brass pipe adapter designed to connect 1/8 inch male NPT tapered threads (MNPTF) to 1/8 inch female British straight pipe parallel threads (FBSPP). This fitting is rated to 1,000 psi, making it suitable for use in compressed air, pneumatic control, and industrial fluid systems where thread-form conversion between inch NPT and BSP standards is required. At 7/8 inches overall length with a 9/16 inch hex, the compact profile fits standard wrench tooling. Plumbers, pipefitters, and industrial maintenance technicians install this adapter wherever legacy BSP-threaded equipment must mate to NPT-threaded domestic piping or instrumentation.

This adapter is used in light industrial, commercial, and OEM equipment applications where thread-standard mismatches occur. Common scenarios include connecting European or Asian-sourced components with BSP ports to NPT-threaded domestic supply lines, hydraulic test panels, pneumatic manifolds, and instrumentation fittings. Its 1,000 psi pressure rating accommodates typical shop air, low-pressure hydraulic, and instrumentation service environments. The all-brass construction resists corrosion in air, water, and many common fluid service conditions.

Key Features

• Converts 1/8 inch MNPTF (tapered) to 1/8 inch FBSPP (parallel) in a single compact fitting
• 1,000 psi pressure rating suitable for pneumatic and light hydraulic service
• Brass construction provides corrosion resistance for air, water, and general fluid applications
• 7/8 inch overall length for minimal footprint in tight installations
• 9/16 inch hex allows installation with standard open-end or combination wrenches

Compatibility

Designed as an OEM-style replacement or direct-fit adapter for industrial piping systems requiring a 1/8 inch MNPTF to FBSPP thread conversion at up to 1,000 psi service pressure.

Installation Notes

Installation should be performed by a licensed pipefitter or qualified industrial maintenance technician. Depressurize and isolate the line completely before removing or installing any fitting. Apply thread sealant or PTFE tape to the NPT male threads as appropriate for the fluid service; BSP parallel threads typically require a bonded seal or O-ring face seal to achieve a leak-free joint. Torque using the 9/16 inch hex to avoid deforming the brass body.
