Product Description

The COILHOSE PNEUMATICS 159 is a brass pneumatic hose coupler designed for compressed air and pneumatic tool connections in industrial and commercial service environments. Built to the Industrial Interchange standard, it accepts a 1/8 inch MNPT thread and features a 1/4 inch body diameter. Rated for a maximum working pressure of 300 psi and a temperature range of -40 to 250 degrees F, this coupler is suited for demanding shop and field pneumatic systems. It is installed by HVAC technicians, industrial maintenance mechanics, and pneumatic equipment service professionals.

This coupler fits standard Industrial Interchange pneumatic fittings and is a common choice for air compressor outlet connections, pneumatic tool lines, and shop air distribution systems. The threaded MNPT connection makes installation straightforward on standard pipe-threaded ports. It is well suited for both permanent installations and service connections in maintenance shops, manufacturing facilities, and mechanical service bays.
