The MIDLAND INDUSTRIES MHY-CIA-18-A is a push-in tee fitting designed for quick, tool-free connections in tubing systems. This fitting accepts 3/8 inch OD tubing on all three ports, allowing a single supply line to branch into two directions without threading, soldering, or compression hardware. It is well-suited for use in HVAC, refrigeration, pneumatic, and fluid-handling applications where fast, reliable connections are required. Licensed technicians and experienced installers rely on push-in fittings like this one to speed up assembly and service work in tight spaces.
This tee fitting is appropriate for residential and light commercial applications involving 3/8 inch OD tubing runs. Common install scenarios include condensate drain branching, pneumatic control lines, and similar low-pressure tubing systems. The push-in design allows tubing to seat and lock with a single straight insertion, making it practical for new installations and field repairs alike.
Designed as an OEM-style replacement or add-on fitting compatible with standard 3/8 inch OD tubing used in HVAC, pneumatic, and fluid-handling systems.
Installation is typically performed by licensed HVAC technicians or plumbers depending on the system type. Before servicing any connected line, shut off supply pressure and depressurize the system completely. Ensure tubing ends are cut cleanly and squarely with a proper tube cutter for a secure seat and leak-free connection. Verify tubing OD matches the fitting specification before insertion.
