Male Conn, 7/8 Comp x 3/4 MIPT

This Midland Metal male connector adapts 7/8-inch compression tubing to a 3/4-inch MIPT threaded connection, providing a robust transition from tubing to threaded plumbing in a single fitting. Built from durable brass, it joins larger-diameter tube runs to standard 3/4-inch female-threaded fittings, valves, control heads, or ports commonly found throughout water treatment and supply systems.

The fitting works in two parts. The compression end accepts 7/8-inch tubing and seals it using a nut and ferrule that clamp the tube as the assembly is tightened. The male NPT thread on the opposite end screws into a matching female fitting. Together, these let you tie a flexible or semi-rigid tube run directly into rigid threaded plumbing without stacking multiple adapters at the joint, which keeps the connection compact and reduces the number of potential leak points. Brass construction provides the strength, corrosion resistance, and longevity needed for continuous-duty service under pressure.

Installers reach for connectors like this one to bring larger tubing into water treatment manifolds, valves, and supply lines, where a clean tube-to-thread transition is needed and a bulky adapter chain would be impractical. The 7/8-inch to 3/4-inch combination is a useful match for routing larger tube runs into standard threaded equipment ports.

For a leak-free joint, apply thread sealant or PTFE tape to the NPT threads before assembly, and make sure the compression nut is tightened firmly over a properly seated, supported tube so the ferrule seals evenly. Durable, versatile, and built to last, this connector is a dependable choice for tube-to-thread transitions on installations and repairs alike, and a worthwhile addition to any installer's parts inventory. Larger tube-to-thread transitions like this one show up wherever bigger feed lines meet standard equipment ports, so having the correct 7/8-inch to 3/4-inch connector on hand avoids the awkward adapter stacks that invite leaks. When making the compression side, a square-cut tube end and a tube support where appropriate help the ferrule seal evenly around the larger 7/8-inch tubing, ensuring the transition is as reliable as the rest of your run.
