Parker B14 Pneumatic Hose Coupler 3/8 Inch Brass

Product Description

The PARKER B14 is a brass pneumatic hose coupler designed for use in compressed-air systems requiring a Tru-Flate Automotive interchange connection. It features a 3/8-18 male NPTF threaded inlet and a 3/8 inch body diameter, with a maximum working pressure of 300 psi. The coupler measures 2.39 inches in overall length and weighs 0.26 pounds. It is suited for use by HVAC technicians, industrial mechanics, and shop maintenance professionals who need a reliable, metal-bodied quick-disconnect coupler for pneumatic tool and hose connections. The brass construction resists corrosion and holds up in demanding shop environments.

This coupler is used in residential and commercial shop settings, vehicle service bays, and light industrial applications where Tru-Flate Automotive interchange fittings are the standard. It connects pneumatic hoses to air tools, blow guns, tire inflators, and similar equipment. The male NPTF thread provides a pressure-sealing fit without a separate sealant in many applications, though thread sealant is still recommended practice. The Series 10 designation identifies the coupling family for matching with compatible plugs in the same interchange series.

Key Features

• Tru-Flate Automotive interchange type for broad compatibility with tools and hoses in that series
• 3/8-18 male NPTF threaded connection for a pressure-sealing mechanical fit
• 300 psi maximum working pressure for typical shop and pneumatic tool use
• Operating temperature range of -40 degrees F to 250 degrees F
• Brass body construction for corrosion resistance and durability
• Compact 2.39 inch overall length with 0.88 inch hex size for standard wrench installation

Compatibility

Designed for use with Tru-Flate Automotive interchange pneumatic systems. Compatible plugs and couplers within the Series 10 family are the appropriate mating components. Consult the Series 10 product line for matching plugs.

Installation Notes

Installation is performed by a qualified mechanic or technician using a standard open-end or adjustable wrench sized to the 0.88 inch hex. Depressurize and bleed down the air line completely before removing or installing any pneumatic fitting. Apply thread sealant tape or paste to male NPTF threads as required by the application and applicable plumbing or pneumatic system standards. Do not exceed the rated 300 psi working pressure for this fitting.
