Parker B15 Pneumatic Hose Coupler 3/8 in Brass Nptf

Product Description

The PARKER B15 is a Tru-Flate style pneumatic hose coupler designed for automotive and light industrial compressed air applications. Built from brass, this coupler features a 3/8-inch body diameter and a 3/8-18 female NPTF threaded inlet, providing a pressure-tight connection without the need for sealant tape when properly mated. The NPTF thread form creates a mechanical seal through thread interference, making it a reliable choice in shop air systems where leak-free connections matter. HVAC technicians, automotive mechanics, and general shop personnel use this coupler to connect pneumatic hoses to air tools, blow guns, and compressed air lines.

This coupler is suited for automotive shop environments, general-purpose compressed air distribution, and light industrial service. The Tru-Flate interchange profile is one of the most widely used coupler styles in North American automotive shops, making this a common replacement or expansion fitting for existing shop air systems. It is typically installed at the tool end of a whip hose or directly at a wall outlet fitting.

Key Features

• Brass construction resists corrosion in compressed air service
• 3/8-18 female NPTF threaded connection for a mechanical pressure-tight seal
• Tru-Flate interchange profile compatible with standard automotive shop air systems
• 3/8 inch body diameter suits common shop air tool hose sizes
• Compact form factor at 2.28 inches in length for use in tight quarters

Compatibility

Designed as a Tru-Flate interchange replacement coupler for 3/8-18 female NPTF threaded pneumatic hose connections in automotive and general shop compressed air systems.

Installation Notes

Installation is performed by a mechanic, HVAC technician, or qualified shop personnel. Depressurize the air line fully before removing or installing any coupler. NPTF threads are designed to seal on the thread form itself, but inspect threads for damage before assembly. Use an appropriately sized wrench and avoid overtightening, which can crack brass fittings.
