1/4″ Quick Connect Coupler, Female NPT, High-Pressure

SKU: NHP502

$1.60

This quick-disconnect coupler plug (also known as an air line nipple or adaptor) is designed for connecting air tools to compressed air hoses. Featuring a 1/4″ female NPT thread, it is made from zinc-plated steel or brass for corrosion resistance and durability. Rated for high-pressure use up to 3,500 PSI (≈ 280 bar) and 250°F maximum temperature, it ensures a secure, leak-free connection in pneumatic, hydraulic, and pressure washer systems.

The Quick-Disconnect Coupler Plug is a standard component in pneumatic and high-pressure systems. Its female threaded design allows easy attachment to hoses or fittings, while the snap-in connection profile (Industrial, ARO, or V-Style High Flow depending on model) ensures compatibility with matching female couplers.

Constructed from heavy-duty zinc-plated steel or brass, it resists rust and corrosion, making it suitable for demanding environments. With a maximum working pressure of 3,500 PSI and temperature resistance up to 250°F, it is ideal for high-pressure washers, hydraulic systems, and chemical applications.

Quick-release functionality saves time during frequent assembly and disassembly, while maintaining a watertight seal for safety and efficiency.
