The PARKER PBH-371-4FP is an industrial pneumatic hose coupler designed for use in compressed air and pneumatic tool applications. It features a 3/8 inch body diameter and a 1/4 inch female NPTF threaded connection, providing a secure, leak-resistant seal without the need for sealant tape on the threads. The coupler body is constructed from polyamide, a lightweight and corrosion-resistant engineering plastic suited for pneumatic service environments. This part is typically installed by HVAC technicians, industrial maintenance mechanics, and pneumatic system specialists working on shop air lines, pneumatic tool hookups, and automation equipment.
This coupler is suited for industrial pneumatic systems where a reliable quick-connect interface is required at an NPTF-threaded port. The 3/8 inch body size accommodates standard industrial interchange pneumatic hose fittings. It is appropriate for both light-duty shop environments and heavier production-floor pneumatic circuits requiring a threaded female entry point. The polyamide construction keeps overall weight low at under 0.25 pounds, making it practical for portable tool setups and overhead installations.
Designed as an OEM-style replacement or direct-fit coupler for industrial pneumatic systems using standard 3/8 inch body industrial interchange fittings with 1/4 inch NPTF female threaded ports.
Installation should be performed by a qualified technician familiar with pneumatic system service. Depressurize and lock out the compressed air supply before removing or installing any pneumatic fittings. NPTF threads are designed to seal on the threads themselves, but inspect threads for damage before installation and do not over-torque the fitting into the mating port. Follow applicable industry standards and equipment manufacturer guidelines for pneumatic system assembly.
