Parker B37 Pneumatic Coupler 1/2in Brass Female Nptf

Product Description

The PARKER B37 is a brass pneumatic hose coupler designed for compressed-air and pneumatic fluid-transfer systems. It features a 1/2-14 female NPTF threaded connection and a 1/2-inch body diameter, conforming to the Series 30 Industrial Interchange standard. Rated for a maximum working pressure of 300 psi and a temperature range of -40 to 250 degrees F, this coupler handles demanding shop and industrial service conditions. Weighing 0.66 pounds, it is a compact, solid-brass fitting installed by HVAC technicians, plumbers, pipefitters, and general industrial mechanics where reliable quick-connect pneumatic coupling is required.

The B37 is suited for use in industrial and commercial facilities wherever Series 30 Industrial Interchange pneumatic couplings are the shop standard. Typical applications include compressed-air distribution systems, pneumatic tool connections, and production-line air-supply lines. The female NPTF threaded body provides a pressure-tight, tapered-thread seal without the need for additional thread sealant in most installations. Its brass construction makes it appropriate for use in environments where corrosion resistance or spark resistance is a consideration.

Key Features

• 1/2-14 female NPTF threaded connection for a reliable pressure-tight tapered-thread seal
• 300 psi maximum working pressure rating suitable for most industrial compressed-air service
• Operating temperature range of -40 to 250 degrees F for broad environmental suitability
• Solid brass construction offers corrosion resistance and durability in demanding service environments
• Overall length of 3.0 inches with a 1.0-inch hex size for standard wrench installation

Compatibility

Designed as an OEM-style replacement or upgrade coupler for pneumatic systems using Series 30 Industrial Interchange fittings with 1/2-14 female NPTF threaded connections.

Installation Notes

Installation should be performed by a qualified mechanic or pipefitter. Depressurize and lock out the air supply completely before removing or installing any pneumatic coupling. Use an appropriate open-end or adjustable wrench on the 1.0-inch hex to tighten to a snug, leak-free fit — do not over-torque brass fittings. Inspect the mating male coupler for thread damage or wear before assembly.
