Coilhose Pneumatics 1108 Pneumatic Hose Coupling 1/4 in

Product Description

The COILHOSE PNEUMATICS 1108 is a pneumatic hose coupling connector designed for compressed air and pneumatic tool systems. Built from steel with a nickel-plated finish, this coupling features a High Flow interchange design and a hose barb thread type for a secure, leak-resistant connection. The 1/4 inch body diameter paired with a 3/8 inch inside diameter hose barb makes it suitable for moderate-to-high flow pneumatic lines. It is installed by maintenance technicians, industrial mechanics, and HVAC or plumbing service professionals who work with air-powered tools and pneumatic control systems.

This coupling is a standard connector fitting used in shop air systems, pneumatic tool lines, and light industrial compressed air distribution. The High Flow interchange design supports higher air volume throughput compared to standard industrial interchange fittings, making it appropriate for impact wrenches, air ratchets, grinders, and other demand tools. It fits into new installations as well as retrofit or repair work on existing pneumatic hose assemblies where a hose barb termination is required.

Key Features

• High Flow interchange design supports higher CFM throughput than standard industrial interchange couplings
• 1/4 inch body diameter with 3/8 inch ID hose barb connection
• Steel construction with nickel-plated finish for corrosion resistance
• Hose barb thread type provides secure grip on pneumatic hose without additional fittings
• Connector-style coupling for straightforward in-line hose termination

Compatibility

Designed as an OEM-style replacement or new-installation connector fitting for High Flow interchange pneumatic systems using 3/8 inch ID hose with a 1/4 inch coupling body.

Installation Notes

Depressurize and bleed all air pressure from the pneumatic line before disconnecting or installing any coupling. This fitting is typically installed by industrial mechanics or pneumatic system technicians using standard hand tools. Ensure the hose barb is fully seated and the hose is secured with an appropriate clamp to prevent blowoff under pressure. Follow applicable OSHA compressed air safety guidelines during service.
