Coilhose Pneumatics 15C90B6M Pneumatic Hose Coupler

Product Description

The COILHOSE PNEUMATICS 15C90B6M is a brass pneumatic hose coupler designed for industrial compressed air systems. It features a 1/4 inch body diameter and a 3/8 inch male NPT (MNPT) threaded connection, making it a straightforward threaded-on fitting for air lines and pneumatic tool circuits. Rated to 300 psi maximum working pressure and suitable for temperatures ranging from -40 degrees F to 250 degrees F, this coupler handles demanding shop and field environments. It follows the Industrial Interchange standard, the most widely used quick-disconnect profile in North American industrial settings. Installation requires no special tools beyond a wrench and appropriate thread sealant.

This coupler is used in residential shops, commercial facilities, and light industrial environments wherever Industrial Interchange-standard quick-disconnect fittings are specified. Typical applications include connecting pneumatic hand tools, air hoses, and accessory lines to manifolds or compressor outlets. The brass construction provides corrosion resistance suitable for dry compressed air service. Mechanical contractors, industrial maintenance technicians, and HVAC service professionals commonly stock this fitting as a standard replacement or expansion component in pneumatic supply systems.

Installation Notes

Installation should be performed by a qualified mechanical technician or HVAC/plumbing professional. Depressurize and lock out the compressed air supply completely before removing or installing any pneumatic fittings. Apply thread sealant tape or compound to the MNPT threads per the fitting manufacturer's guidance and applicable shop practices. Do not exceed the 300 psi maximum working pressure rating of this coupler.
