Parker PBS-371-6FP Pneumatic Coupler 3/8 in Nptf 300 Psi

Product Description

The PARKER PBS-371-6FP is a pneumatic hose coupler designed for use in compressed air and pneumatic tool systems. It features a 3/8 inch female NPTF threaded connection and a 3/8 inch body diameter, making it a standard industrial interchange coupler. Built from polyamide, this coupler handles a maximum working pressure of 300 psi and operates across a temperature range of 0 to 160 degrees F. At 0.15 pounds, it is lightweight and suited for frequent connect-disconnect service. Licensed HVAC technicians, industrial maintenance techs, and pneumatic system installers typically source this fitting when maintaining or assembling air tool circuits.

This coupler fits standard industrial interchange pneumatic systems, including air compressor drop lines, portable air tool setups, and inline pneumatic circuits. The female NPTF thread is compatible with standard pipe-thread fittings commonly found in shop and field pneumatic installations. Its polyamide construction resists wear and corrosion in typical compressed air environments. It is suitable for light industrial and commercial applications where a threaded coupler connection is required at the 3/8 inch line size.

Key Features

• Industrial interchange coupler type for broad compatibility with standard pneumatic quick-connect systems
• 3/8 inch female NPTF threaded connection for secure, leak-resistant engagement
• 300 psi maximum working pressure rating for standard compressed air service
• Polyamide body construction for lightweight durability and corrosion resistance
• Operating temperature range of 0 to 160 degrees F covers typical shop and field conditions
• Overall length of 2.95 inches with a 0.82 inch hex size for wrench installation

Compatibility

Designed as an industrial interchange-style replacement coupler for 3/8 inch female NPTF threaded pneumatic hose and tool connections in standard compressed air systems.

Installation Notes

Installation is performed by a qualified pneumatic or mechanical technician. Depressurize and bleed the air line completely before removing or installing any coupler. Apply thread sealant appropriate for pneumatic service to the NPTF threads before assembly. Use a wrench on the 0.82 inch hex to achieve a secure, leak-free connection without over-tightening the polyamide body.
