Parker PBH-251-6MP Pneumatic Hose Coupler 3/8 Male Nptf

Product Description

The PARKER PBH-251-6MP is an industrial pneumatic hose coupler designed for compressed air and pneumatic tool applications. Built with a polyamide body measuring 0.25 inches in diameter, it features a 3/8-inch male NPTF threaded connection that creates a pressure-tight seal without additional sealant tape in many installations. This coupler connects pneumatic hoses to air tools, compressors, and distribution lines. HVAC technicians, plumbers, and industrial maintenance professionals install this fitting where a durable, lightweight coupler is needed in a compressed air system.

This coupler is suited for light-to-medium duty pneumatic systems in residential and commercial service environments. The threaded NPTF connection is a standard configuration found on portable air compressors, pneumatic impact tools, blow guns, and shop air lines. The polyamide construction makes it appropriate for use where reduced weight is a priority without sacrificing serviceability in routine pneumatic maintenance work.

Key Features

• 3/8-inch male NPTF threaded connection for pressure-tight fitment
• 0.25-inch body diameter in standard industrial coupler sizing
• Polyamide body construction for lightweight durability
• Threaded connection type allows tool-free hand-start engagement
• Single-unit packaging suitable for individual replacement or service kit use

Compatibility

Designed as an OEM-style replacement or service fitting for standard industrial pneumatic hose systems using 3/8-inch male NPTF threaded couplers with a 0.25-inch body diameter.

Installation Notes

Installation should be performed by a qualified technician familiar with pneumatic system service. Depressurize the air line completely before removing or installing any coupler or fitting. NPTF threads are designed to seal on the threads themselves, but applying thread sealant consistent with your shop practice and local code is acceptable. Inspect mating threads for damage before assembly to avoid cross-threading or leaks.
