Milton 717 barbed coupler body is an air line fitting in the Kwik Change M Style family, so it serves as a quick-connect point in compressed air systems where M Style couplers are standard. The coupler body is made from brass, which resists corrosion in normal shop air environments and helps threads and sealing surfaces stay workable over repeated connects and disconnects. Its sleeve is also brass, so the sliding action that connects the line stays smooth in regular use. This air line component is classified as an air coupler body, so it plays the central role of controlling connection between a barbed hose end and mating M Style plug fittings. The fitting is part of Milton Industries air line components, giving installers a consistent part number to specify in shop layouts and compressed air drops.
The Milton 717 barbed coupler body is identified as a 1/4 inch barbed coupler body, so it is set up for use where 1/4 inch barbed hose connections are required on an air line. As part of the Kwik Change M Style system, the coupler body is used where M Style quick-change air connections are already specified in the shop or at workstations. The barbed design lets the coupler body serve as the transition between flexible hose and the M Style quick-connect side, supporting layouts that run hose out from a fixed air supply. With its air line components classification, this coupler body fits into compressed air distribution work where installers are balancing hose size, pressure rating, and connection style for tools and stations.
The SAP description defines this product as BARBED COUPLER BODY,1/4', so it is intended for air line runs that are built around 1/4 inch barbed hose interfaces. In applications using Kwik Change M Style connections, this Milton Industries coupler body provides the fixed-side component that mates with matching plugs from air tools or extension hoses. Because the body and sleeve are brass, the coupler suits shop environments where metal fittings might be exposed to moisture in compressed air lines, helping the connection resist corrosion in normal service. The case hardened steel drag guard is especially relevant in busy woodworking or industrial spaces, since the hardened guard helps shield working surfaces of the coupler when hoses are dragged across floors, under benches, or around machinery.
The 300 PSI maximum inlet pressure rating defines the upper pressure limit this air line coupler body is intended to handle, giving designers a clear specification when tying into compressed air systems that operate within that range. With a maximum temperature of 250 F, the coupler body is specified for compressed air applications where air may be hot yet still within this limit, helping maintain seal performance and material stability. The 40 SCFM air flow rating gives a benchmark for how much air volume the coupler body is designed to pass, which matters when sizing air lines to serve tools or circuits needing that airflow. Buna-N seals inside the coupler body provide the sealing interface, so internal sealing behavior is tied to Buna-N characteristics in compressed air usage. The combination of brass body, brass sleeve, hardened steel drag guard, and these pressure, temperature, and flow ratings lets installers select this Milton Industries air coupler body with a clear view of how it will perform as part of a planned air distribution layout.
The Milton 717 is a Kwik Change M Style barbed coupler body, so it works as the M Style quick-connect component in compressed air systems using that connection standard.
The product is described as BARBED COUPLER BODY,1/4', indicating it is intended for use with 1/4 inch barbed hose connections on air lines.
The coupler bodies are brass with brass sleeves, so both the main body and the moving sleeve use brass to support corrosion resistance and consistent sliding action.
The coupler body has a case hardened steel drag guard, giving a hardened surface that helps protect the fitting from wear or impact when hoses are pulled across work areas.
This Milton Industries coupler body has a maximum inlet pressure of 300 PSI and a maximum temperature of 250 F, defining its working envelope in compressed air systems.
The air flow rating is 40 SCFM, so the coupler body is specified to pass 40 standard cubic feet per minute in suitable air line layouts.
The Milton 717 barbed coupler body combines brass construction, a case hardened steel drag guard, Buna-N seals, and Kwik Change M Style configuration, giving installers a clearly specified air line fitting. With 300 PSI, 250 F, and 40 SCFM ratings, this Milton Industries air coupler body offers defined limits for pressure, temperature, and flow. For air line projects needing a 1/4 inch barbed coupler body with these characteristics, Wurth Baer Supply provides this Milton air line component as a part-numbered option for planned compressed air layouts.
