Product Description

The COILHOSE PNEUMATICS 587 is a male NPT pneumatic coupler designed for connecting and disconnecting air lines in compressed air systems. Built from nickel-plated steel, it features a 1/2 inch MNPT thread and a 3/8 inch body diameter. It is rated for a maximum working pressure of 300 psi and operates across a temperature range of -40 degrees F to 250 degrees F. This coupler follows the Industrial Interchange standard, making it compatible with the most widely used quick-connect pneumatic fittings in the field. It is installed by HVAC technicians, pipefitters, and maintenance professionals who work with shop air and pneumatic tool systems.

This coupler is suited for use in industrial, commercial, and shop environments where reliable, repeatable air line connections are required. It fits threaded ports on compressors, air distribution manifolds, hose assemblies, and pneumatic tool drops. The Industrial Interchange design is the most common quick-connect standard in North American shops and production facilities, making this coupler a practical stock item for field service kits and maintenance carts.
