Value Collection 2542572521 Pneumatic Coupling Plug Set 10pc

Product Description

The Value Collection 2542572521 is a 10-piece industrial pneumatic coupling plug set designed for use in compressed air systems. Each plug features a 1/4-inch body size and 1/4 NPT thread connection, rated to 215 psi working pressure. The set includes 10 female connectors machined from heat-treated steel for durability in high-cycle shop and industrial environments. Licensed HVAC technicians, plumbers, and industrial maintenance professionals use these plugs to complete air line quick-disconnect setups quickly and reliably.

This coupling plug set suits a wide range of industrial and trade applications where standard NPT-threaded compressed air connections are required. The 1/4-inch body size is among the most common in shop air systems, making this set a practical addition to service vans, maintenance shops, and light industrial facilities. The plugs mate with standard industrial-interchange quick-connect couplers already in widespread use across HVAC, plumbing, and general maintenance trades.

Key Features

• Set of 10 female connectors — stock multiple air lines or replace worn plugs in a single purchase
• 215 psi pressure rating suitable for standard shop air systems
• 1/4 NPT thread standard for broad compatibility with common air fittings
• Heat-treated steel construction for resistance to wear and deformation under repeated coupling cycles
• 1/4-inch body size matches the most prevalent industrial quick-disconnect profile

Compatibility

Designed for use with standard industrial-interchange quick-connect pneumatic systems utilizing 1/4 NPT threaded connections and 1/4-inch body couplers.

Installation Notes

Installation is typically performed by HVAC technicians, plumbers, or general maintenance personnel familiar with compressed air systems. Depressurize and bleed the air line completely before removing or installing any coupling or plug. Apply thread sealant tape or compound to NPT threads per standard practice before hand-tightening and then wrench-tightening to avoid cross-threading. Inspect plugs for damage or wear before placing them into service.
