Midland Metal 28528s Interchange Male Coupler 1/4 in Mip

Product Description

The MIDLAND METAL 28552s is an industrial interchange male coupler designed for use in compressed air and pneumatic tool systems. Featuring a 1/4-inch body and a 1/4-inch male NPT (MIP) thread, this coupler provides a reliable quick-connect interface between air hoses, fittings, and pneumatic equipment. Constructed from steel, it is built to withstand the mechanical stress and pressure cycles common in shop and field environments. Licensed HVAC technicians, plumbers, and general contractors rely on couplers like this for tool hookups, blow-off guns, and pneumatic controls.

This coupler fits standard industrial interchange series pneumatic systems and is suited for both residential and light commercial shop applications. The industrial interchange profile is one of the most widely used quick-connect standards in North American trades, making it compatible with a broad range of air tools, compressors, and manifold assemblies. It is appropriate for any compressed air distribution setup requiring a 1/4-inch NPT male inlet connection.

Key Features

• 1/4-inch body size for standard industrial interchange compatibility
• 1/4-inch male NPT thread for secure, leak-resistant connection
• Steel construction for durability under repeated connect-disconnect cycles
• Industrial interchange series profile — widely accepted across trade applications
• Compact form factor suited for tight pneumatic plumbing layouts

Compatibility

Designed as an OEM-style replacement or new-installation coupler for industrial interchange series pneumatic systems using 1/4-inch male NPT connections.

Installation Notes

Installation is typically performed by HVAC technicians, plumbers, or general mechanics working on compressed air systems. Always depressurize the air line and bleed residual pressure before disconnecting or installing any coupler. Apply thread sealant tape to the male NPT threads in accordance with standard practice and applicable plumbing or mechanical codes. Do not overtighten — hand-tighten plus wrench snug is sufficient to seat the NPT threads without cracking the fitting body.
