Parker 1 1/4 X 1 Ptr-s Pipe Bushing Mnptf X Fnptf 3000 Psi

Product Description

The PARKER 1 1/4 X 1 PTR-S is a straight pipe bushing designed to reduce a 1-1/4 inch male MNPTF thread down to a 1 inch female FNPTF thread in hydraulic, pneumatic, and industrial piping systems. Rated to 3,000 psi maximum working pressure, this bushing handles demanding pressure environments without compromise. The hex drive measures 1-3/4 inches for easy wrench engagement, and the overall length is 1-1/2 inches. Weighing 0.37 pounds, it is a compact, solid fitting suited for permanent installation in fluid power and process piping assemblies by qualified pipefitters, plumbers, and mechanical contractors.

This bushing is used wherever a piping or hydraulic circuit requires a reduction from 1-1/4 inch MNPTF to 1 inch FNPTF. Common install scenarios include industrial hydraulic manifolds, compressed air distribution systems, water supply headers, and process fluid lines in commercial and light industrial facilities. The MNPTF x FNPTF thread configuration ensures a pressure-tight, tapered thread seal appropriate for stationary pipe connections. Sold individually, it fits single-point repair or new-construction applications alike.

Key Features

• 3,000 psi maximum working pressure for high-demand hydraulic and pneumatic systems
• 1-1/4 inch male MNPTF to 1 inch female FNPTF straight reducing configuration
• 1-3/4 inch hex size allows standard wrench or pipe wrench engagement
• 1-1/2 inch overall length for compact in-line installation
• Tapered NPT threads on both ends provide a reliable pressure-tight seal

Compatibility

Designed as an OEM-style replacement or new-installation fitting for industrial and hydraulic piping systems using standard MNPTF x FNPTF tapered pipe thread connections in 1-1/4 inch by 1 inch reducing configurations.

Installation Notes

Installation should be performed by a qualified pipefitter, plumber, or hydraulic technician. Depressurize and isolate the system completely before removing or installing any threaded fitting. Apply thread sealant or PTFE tape appropriate for the fluid type and pressure rating to the male threads before assembly. Tighten to the fitting manufacturer's recommended engagement depth using a properly sized wrench on the hex drive — do not over-tighten tapered NPT threads.
