The PARKER X1/2FHG4-B is a brass pipe adapter designed to connect male National Pipe Taper Fuel (MNPTF) threads to female British Standard Pipe Parallel (FBSPP) threads in industrial piping systems. Rated to 1,000 psi, this adapter measures 1.75 inches in overall length and features a 1-1/16 inch hex for standard wrench engagement. It is a single-piece, sold-individually fitting used by pipefitters, plumbers, and industrial maintenance technicians to transition between NPT and BSP thread standards without additional components.
This adapter is suited for industrial fluid and pneumatic piping applications where MNPTF and FBSPP thread conversion is required. The 1/2 inch male and 1/2 inch female thread sizes make it a common fit in hydraulic lines, compressed air systems, fuel lines, and general-purpose industrial plumbing. Its brass construction provides corrosion resistance in a range of media, including water, air, and light petroleum-based fluids.
Designed as an OEM-style replacement or upgrade adapter for industrial piping systems requiring a 1/2 inch MNPTF to 1/2 inch FBSPP thread conversion rated to 1,000 psi.
Installation should be performed by a qualified pipefitter or industrial maintenance technician. Depressurize and isolate the line completely before removing any existing fittings or installing this adapter. Apply appropriate thread sealant compatible with the system media and thread types before assembly. Do not exceed the rated working pressure of 1,000 psi in service.
