5 In ONE Universal Quick-Connect Coupler gives you a single pneumatic coupler that connects to all major interchanges, so one fitting can serve different tools and hoses in the shop. This Milton Industries S-743 coupler is a 1/4 inch body design with 1/4 inch female NPT threads, which lets it thread directly onto air lines or hose ends built around that common size. The universal industrial design accepts Industrial M-style, high flow V-style, automotive T-style, ARO A-style, and Lincoln L-style plugs, so mixed fleets of tools stay usable without changing fittings. Heavy-duty steel construction provides a robust coupler body that stands up to typical air line environments. Six ball bearings are used inside the coupler to support longer life, which helps reduce downtime from worn connections. The quick connect coupling action delivers safe and easy air hose connection during regular tool changeovers.
This Milton 5 In ONE universal industrial coupler uses 1/4 inch female NPT threads, which lets it screw onto 1/4 inch NPT male ends on hoses or manifolds for a direct connection into the air system. The 1/4 inch body size aligns the coupler flow path with standard air line sizing used around small and medium pneumatic tools. Its universal acceptance of M-style, V-style, T-style, A-style, and L-style plugs means those plug types can be plugged in without changing the coupler, which streamlines hookup when multiple plug standards are present on tools. Six internal ball bearings support the connection around the plug for longer life, which keeps the coupler engaging smoothly over repeated use.
The 5 In ONE Universal Quick-Connect Coupler is an air line fitting for pneumatic systems that need to connect tools with Industrial M-style, high flow V-style, automotive T-style, ARO A-style, or Lincoln L-style plugs at a single point. Its 1/4 inch female NPT interface allows the coupler to be integrated at hose ends, drop lines, or manifolds that are threaded with 1/4 inch NPT, keeping the flow path sized for typical shop air circuits. With a 1/4 inch body, the coupler is well suited to many hand-held air tools that run within the stated pressure and flow values, so tools using those plug styles can be tied into the same air source through one universal fitting.
The universal industrial design of this Milton S-743 coupler accepts Industrial M-style, V-style, T-style, A-style, and L-style plugs, which allows a single quick connect point to service different plug patterns without changing couplers between tools. Its heavy-duty steel construction provides a durable body that stands up to the repeated motion of connecting and disconnecting tools in pneumatic use. Six ball bearing construction inside the coupler is designed for longer life, which keeps the plug engagement stable and helps maintain sealing performance over time. Rated operation up to 120 PSI, with published air flow values at 80, 90, 100, and 120 PSI, shows how the coupler supports airflow across common shop pressures so tools receive consistent air supply when matched to those pressure and flow figures. The quick connect coupling design delivers a fast plug-in action for air hose connection, which streamlines workflow when tools are swapped frequently during the workday.
The 5 In ONE Universal Quick-Connect Coupler accepts Industrial M-style, high flow V-style, automotive T-style, ARO A-style, and Lincoln L-style plugs, so multiple plug patterns can connect at one air point.
The Milton S-743 coupler has 1/4 inch female NPT threads, allowing direct connection to 1/4 inch NPT male fittings on hoses, manifolds, or air tools set up with that thread.
The 5 In ONE Universal Quick-Connect Coupler is rated for a maximum of 120 PSI, aligning it with air systems operating within that pressure range.
The six ball bearing construction in the Milton S-743 supports longer life by stabilizing the plug connection, which helps the coupler engage smoothly over repeated cycles.
The coupler lists airflow at 80 PSI at 31 or 44 CFM, 90 PSI at 34, 35, or 50 CFM, 100 PSI at 36, 37, or 50 CFM, and 120 PSI at 44, 45, or 67 CFM.
This Milton Industries air line fitting is designed as a universal industrial pneumatic coupler for applications needing a durable, long lasting quick-connect point for varied plug styles.
The Milton Industries 5 In ONE Universal Quick-Connect Coupler S-743 brings Industrial M-style, high flow V-style, automotive T-style, ARO A-style, and Lincoln L-style compatibility into a single 1/4 inch female NPT fitting, simplifying mixed-plug air setups. Heavy-duty steel construction, six ball bearing internals, and a 120 PSI rating give this 1/4 inch body air line fitting the capability needed for regular pneumatic use. For air systems built around 1/4 inch NPT, this universal coupler offers a straightforward way to connect varied plug types through one quick connect point.
