Parker 3/4 X 1/2 Ptr-s Pipe Bushing Mnptf X Fnptf 5000 Psi

Product Description

The PARKER 3/4 X 1/2 PTR-S is a straight pipe bushing designed to reduce a 3/4 inch male NPT fitting down to a 1/2 inch female NPT port. Constructed from zinc-plated steel, it handles a maximum working pressure of 5,000 psi, making it suitable for high-pressure hydraulic and industrial piping systems. The MNPTF x FNPTF connection type provides a tapered thread seal on both ends. Licensed plumbers, pipefitters, and hydraulic system technicians install this fitting when reducing port or line sizes in fluid power, pneumatic, or industrial plumbing assemblies.

This bushing is used in residential and commercial industrial piping applications where a threaded port reduction is required. Typical install scenarios include hydraulic power units, compressed air distribution systems, and industrial fluid handling manifolds. The straight configuration and standard NPT thread form make it a common stock item for service vans and shop plumbing retrofit work. It ships individually and is sold as a single unit.

Key Features

• 5,000 psi maximum working pressure for high-pressure hydraulic and pneumatic service
• Zinc-plated steel construction provides corrosion resistance in industrial environments
• MNPTF x FNPTF tapered thread connection on both male and female ends
• Straight bushing shape for in-line port size reduction
• 3/4 inch male thread to 1/2 inch female thread reduction in a single fitting
• 1-1/8 inch hex size allows standard wrench installation

Compatibility

Designed as an OEM-style replacement or service fitting for industrial piping and fluid power systems using standard MNPTF x FNPTF threaded connections requiring a 3/4 inch to 1/2 inch reduction.

Installation Notes

Installation is performed by licensed plumbers, pipefitters, or hydraulic technicians. Depressurize and isolate the system completely before removing or installing any threaded fittings. Apply an appropriate thread sealant or PTFE tape to the male threads in accordance with system fluid compatibility and applicable codes such as the IPC or IFGC. Do not over-torque tapered NPT threads, as this can crack fittings or damage mating ports.
