Air Hose Fittings 1/4″ NPT Female Plug Qolekog Brass 2‑Piece

Description

Product Overview

The Qolekog 1/4 inch NPT female air plug is engineered from high‑grade solid brass, a material chosen for its superior wear resistance, corrosion tolerance, and long service life compared with aluminum or plastic alternatives. Each plug features a precisely machined 0.25‑inch FNPT thread that conforms to industry standards, guaranteeing a tight, leak‑free seal when paired with compatible male couplers. The brass construction not only endures the rigors of daily use but also maintains a smooth, polished surface that reduces friction during connection and disconnection, extending the lifespan of both the fitting and the hose.

Designed for demanding environments, this fitting supports a maximum operating pressure of 300 psi, making it suitable for a wide range of pneumatic tools and equipment. The compact form factor, measuring just 2.36 × 1.97 × 0.67 inches, allows it to fit into tight spaces without compromising performance. We provide the product in a convenient two‑piece package, enabling users to create custom hose assemblies or replace worn components quickly. The included components are two identical female plugs, each weighing only 0.03 kg, which contributes to a lightweight yet robust solution for portable and stationary applications alike.

Usage

Professionals and hobbyists alike will find the Qolekog female air plug indispensable in a variety of settings. In automotive workshops, the fitting connects air compressors to impact wrenches, spray guns, and tire inflators, delivering consistent airflow for efficient operation. For construction sites, the plug links portable compressors to nail guns and concrete vibrators, where reliability under high pressure is critical. Outdoor enthusiasts use the fitting with pressure washers and garden equipment, benefiting from its resistance to moisture and dust.

The plug’s universal compatibility with M, D, and I/M type air couplers means it can be paired with most manufacturers’ hose systems, reducing the need for multiple specialized fittings. Whether you are assembling a custom air line for a paint sprayer, extending a hose for a blow gun, or repairing a broken connection on a pneumatic drill, the Qolekog plug provides a secure, easy‑to‑install solution. Its screw‑in installation method requires only a standard wrench, allowing for rapid setup and minimal downtime.
