YUNXUNTENGLONG 45-Piece 1/4 NPT Air Hose Fittings Kit – Quick Connect, Brass & Copper-Plated

Complete 45-Piece Air Hose Fittings Kit

This 45-piece set is designed for leak-free pneumatic connections across home workshops, garages, and industrial spaces. It brings together a full range of male and female plugs, couplers, hex fittings, and a roll of PTFE tape to help you assemble quickly and confidently.

Durable, High-Quality Components

Brass hex couplers and connectors provide rust resistance and solid strength under pressure, while copper-plated iron cores offer wear resistance and cost-effective durability. The kit is engineered to perform reliably in environments where moisture, oil, and routine use are common.

Key materials and design details support long-term reliability while maintaining a compact form that fits neatly in a tool bag or cabinet corner.

Reliable Quick Connect and Leak Control

The connector uses four large locking balls to secure the plug and prevent unexpected disconnection. The quick connect design allows tool-free installation, and the 1/4 NPT threads pair with PTFE tape to minimize leaks and fit with most air hoses and tools.
