Parker X1/4FHG4-B Pipe Adapter 1/4 in Mnptf X Fbspp Brass

Product Description

The PARKER X1/4FHG4-B is a brass pipe adapter designed to connect a 1/4 inch male NPT fitting (MNPTF) to a 1/4 inch female BSPP port (FBSPP). It bridges the common NPT-to-BSPP thread standard difference found in industrial fluid and pneumatic systems. Rated to 1000 psi, this adapter is built for demanding service environments where a reliable, leak-free thread conversion is required. The brass construction resists corrosion and is compatible with a wide range of media. Licensed plumbers, pipefitters, and industrial maintenance technicians are the typical installers.

This adapter is suited for use in industrial piping assemblies, pneumatic lines, hydraulic systems, and compressed air distribution where MNPTF and FBSPP connections must be joined. It is a compact, single-piece fitting appropriate for both original equipment installations and field maintenance work. The 1-5/16 inch overall length and 3/4 inch hex size allow for straightforward wrench installation in tight spaces.

Key Features

• Converts 1/4 inch MNPTF to 1/4 inch FBSPP thread standard
• Rated to 1000 psi working pressure
• Brass construction for corrosion resistance across a broad range of media
• 3/4 inch hex size for standard wrench installation
• Overall length of 1-5/16 inches for compact fitment

Compatibility

Designed as an OEM-style replacement or system adapter for industrial piping, pneumatic, and hydraulic assemblies requiring a 1/4 inch MNPTF to 1/4 inch FBSPP thread conversion.

Installation Notes

Installation is typically performed by a licensed pipefitter, plumber, or industrial maintenance technician. Depressurize and isolate the line before removing or installing any fitting. Apply appropriate thread sealant to the MNPTF threads per the system fluid compatibility requirements. Use a correctly sized wrench on the 3/4 inch hex to avoid deforming the fitting body; do not over-tighten.
