Value Collection 2312572511-4 Pneumatic Hose Coupler

Product Description

The VALUE COLLECTION 2312572511-4 is a six-ball pneumatic hose coupler designed for use in industrial compressed-air systems. Machined from brass, it features a 1/4-inch female NPT (FNPT) thread and a 1/4-inch body diameter, making it a compact, durable fitting for connecting air lines and pneumatic tools. With a maximum working pressure of 145 psi, it handles typical shop-air and light industrial supply pressures without issue. The six-ball locking mechanism provides a secure, leak-resistant connection that releases cleanly under shop conditions. Plumbers, pipefitters, and industrial maintenance technicians routinely install this type of coupler during pneumatic system assembly or repair.

This coupler follows the Industrial Interchange standard, the most widely used quick-connect profile in North American workshops and industrial facilities. It is suited for residential shop environments, light manufacturing, MRO (maintenance, repair, and operations) applications, and any compressed-air distribution system requiring a reliable 1/4-inch FNPT entry point. The brass construction offers good resistance to corrosion in typical dry-air service, making it appropriate for both stationary and portable compressor setups.

Key Features

• Six-ball locking mechanism for a secure, positive connection
• Brass construction provides corrosion resistance in dry compressed-air service
• 1/4-inch FNPT thread for straightforward pipe-thread installation
• 1/4-inch body diameter compatible with standard Industrial Interchange plugs
• Rated to 145 psi maximum working pressure
• Industrial Interchange profile — the most common quick-connect standard in North American shops

Compatibility

Designed as an OEM-style replacement or service coupler for Industrial Interchange pneumatic systems using 1/4-inch FNPT connections and standard 1/4-inch body quick-connect plugs.

Installation Notes

Installation is typically performed by a pipefitter, industrial maintenance technician, or experienced pneumatic-system installer. Depressurize and bleed the air line completely before removing or installing any coupler. Apply thread sealant tape or compound to the FNPT threads per standard pipe-fitting practice, and do not overtighten, as brass threads can be damaged by excessive torque. Verify the line pressure does not exceed the 145 psi rated maximum before returning the system to service.
