Parker B38 Male Npt Pneumatic Hose Coupler 3/4 Inch

Product Description

The PARKER B38 is a 3/4-inch male NPT industrial pneumatic hose coupler machined from brass. It serves as the male half of a quick-connect coupling assembly, attaching compressed air hoses and pneumatic tools to air supply lines, manifolds, or other threaded ports. The 3/4-14 NPT thread provides a secure, leak-resistant connection standard to industrial air distribution systems. At 0.91 pounds, it is a solid, single-piece fitting suited for permanent or field installation by HVAC technicians, pipefitters, plumbers, or industrial mechanics working on compressed air networks.

This coupler is designed for industrial pneumatic applications where a reliable, threaded male NPT connection is required at a 3/4-inch body diameter. Typical installations include workshop air lines, production floor compressed air drops, HVAC equipment air supply connections, and pneumatic control systems. The brass construction resists corrosion in typical compressed air environments and is compatible with standard industrial interchange coupler bodies and sleeves.

Key Features

• 3/4-14 NPT male thread for secure, standard-compliance connection to NPT-tapped ports and fittings
• Brass construction provides corrosion resistance in typical compressed air service
• 3/4 inch body diameter suits high-flow industrial pneumatic hose assemblies
• Threaded connection type enables tool-free installation with pipe wrench or open-end wrench
• Single-piece coupler body minimizes leak points in the air line assembly

Compatibility

Designed as an OEM-style male NPT coupler for industrial pneumatic hose and fitting systems using 3/4-inch NPT threaded connections.

Installation Notes

Installation is performed by pipefitters, HVAC mechanics, or qualified pneumatic system technicians. Depressurize and bleed the air line completely before removing or installing any coupler. Apply thread sealant tape or pipe compound rated for compressed air service to the NPT threads before engagement. Connections should conform to applicable local mechanical codes and the compressed air system operating pressure rating of all installed components.
