Parker PBS-371-8FP Pneumatic Hose Coupler 1/2 Female Nptf

Product Description

The PARKER PBS-371-8FP is a female NPTF pneumatic hose coupler designed for industrial compressed-air systems. The coupler body measures 3/8 inches in diameter and connects via a 1/2 inch female NPTF threaded fitting, providing a secure, leak-resistant seal without the need for additional tape or thread sealant in many applications. The body is constructed from polyamide, offering corrosion resistance and durability in demanding shop and field environments. This part is sold as a single unit and is a standard component used by HVAC technicians, plumbers, pipefitters, and industrial maintenance professionals when assembling or repairing compressed-air distribution lines and pneumatic tool connections.

This coupler is suited for industrial pneumatic systems in both commercial and light-industrial settings. It is typically installed at hose-to-header connections, quick-disconnect stations, or inline tool drop points where a threaded female NPTF connection is required. Its polyamide construction makes it appropriate for dry or lightly lubricated air service. Technicians working on production floors, service shops, and mechanical rooms will find this a straightforward replacement or new-installation component for standard industrial pneumatic coupler configurations.

Key Features

• 1/2 inch female NPTF threaded connection for a pressure-tight seal
• 3/8 inch body diameter matches standard industrial coupler sizing
• Polyamide body construction resists corrosion and chemical exposure
• Threaded connection type for secure, repeatable assembly
• Sold as a single unit for precise quantity purchasing

Compatibility

Designed as an OEM-style replacement or new-installation coupler for industrial pneumatic systems requiring a 1/2 inch female NPTF threaded coupler with a 3/8 inch body diameter.

Installation Notes

Installation should be performed by a qualified technician with the compressed-air system fully depressurized and locked out before service. Verify that the mating fitting thread form is compatible with NPTF before assembly, as mixing thread standards can result in leaks or damage. Use appropriate thread sealant or PTFE tape as required by site standards and applicable plumbing or mechanical codes. Inspect the coupler body for damage before installation and torque to fitting manufacturer recommendations based on connection size.
