Parker 1/2 X 1/8 Ptr-s Pipe Bushing 6000 Psi Mnptf X Fnptf

Product Description

The PARKER 1/2 X 1/8 PTR-S is a zinc plated steel pipe bushing designed to reduce a 1/2 inch male NPTF thread down to a 1/8 inch female NPTF thread. It is rated to 6,000 psi, making it suitable for high-pressure hydraulic and industrial pneumatic plumbing systems. The connection type is MNPTF x FNPTF, providing a pressure-tight dry-seal thread fit without requiring sealant tape on properly gauged threads. This bushing is installed by plumbers, pipefitters, and hydraulic system technicians working on industrial fluid power or process piping assemblies.

This bushing is used in industrial and commercial piping applications where a straight thread reduction between two NPT ports is required. Typical scenarios include manifold port reduction, hydraulic cylinder port adaptation, and instrumentation line connections. The 6,000 psi pressure rating makes it appropriate for high-pressure hydraulic circuits as well as compressed air and fluid transfer systems that demand reliable thread engagement under sustained working pressure.

Key Features

• 6,000 psi pressure rating for high-pressure hydraulic and pneumatic service
• MNPTF x FNPTF dry-seal thread connection resists leakage at thread interface
• Zinc plated steel construction provides corrosion resistance in industrial environments
• Reduces 1/2 inch male thread to 1/8 inch female thread in a single fitting
• 7/8 inch hex size for standard wrench installation
• Compact profile at 1.11 inches length keeps installation envelope tight

Compatibility

Designed as an OEM-style replacement or drop-in fitting for industrial pipe systems using standard MNPTF x FNPTF thread configurations with a 1/2 inch to 1/8 inch port reduction.

Installation Notes

Installation is performed by licensed plumbers, pipefitters, or hydraulic technicians. De-energize and depressurize the system fully before removing or installing any threaded fittings. MNPTF dry-seal threads are designed to seal on the threads themselves — inspect threads for damage before assembly and apply appropriate thread sealant per system fluid compatibility requirements. Tighten to proper engagement using a wrench on the hex; do not over-tighten, as this can crack the fitting or damage port threads.
