Parker PBH-251-4MP Pneumatic Hose Coupler 1/4 in Male Nptf

Product Description

The PARKER PBH-251-4MP is a 1/4 inch male NPTF industrial pneumatic hose coupler designed for compressed air and pneumatic tool connections in trade and industrial service environments. The body is constructed from polyamide, a durable engineering-grade thermoplastic well suited for pneumatic service. The threaded NPTF connection provides a pressure-tight mechanical seal without sealant tape on properly mated fittings. This coupler is used by HVAC technicians, plumbers, industrial mechanics, and general contractors who work with pneumatic tools and air supply lines.

This coupler fits standard industrial pneumatic hose and tool setups where a 1/4 inch male NPTF threaded interface is required. It is suited for workshop, job site, and light industrial compressed air systems. The polyamide body keeps weight low while maintaining adequate strength for typical shop-air pressure ranges. Sold individually, it works as a direct replacement or addition to existing pneumatic quick-connect systems using the industrial interchange standard.

Key Features

• 1/4 inch body diameter with male NPTF threaded connection for a leak-resistant mechanical seal
• Polyamide construction reduces weight while providing resistance to oils and common shop chemicals
• Industrial interchange coupler profile compatible with widely used pneumatic quick-connect systems
• Threaded connection type allows secure attachment without additional fittings
• Lightweight at 0.135 pounds for easy handling and low added weight on hose assemblies

Compatibility

Designed as an OEM-style replacement or add-on coupler for industrial pneumatic systems utilizing a 1/4 inch male NPTF threaded interface.

Installation Notes

Installation is performed by a qualified mechanic or tradesperson familiar with pneumatic systems. Always depressurize and bleed down the air supply line before removing or installing any coupler. NPTF threads are designed to seal on the threads themselves, but inspect thread condition before installation and apply thread sealant if required by the specific fitting or system manufacturer. Verify that the mating quick-connect body is fully depressurized before engaging or disengaging the coupler.
