The MIDLAND INDUSTRIES 20776P is an acetal plastic 2-way divider fitting designed to split a single pneumatic or fluid line into two branches using push-in connections on all three ports. Each port accepts 5/16-inch OD tubing and is rated for up to 170 psi at temperatures ranging from 34 degrees F to 150 degrees F. The acetal construction resists moisture and common shop fluids while keeping weight minimal at 0.025 pounds. This fitting is installed by HVAC technicians, plumbers, and pneumatic system mechanics who need a compact, tool-free branch connection in low-pressure tubing circuits.
This divider fitting is suited for residential and light commercial applications where a single supply line must feed two downstream devices or zones. Typical uses include pneumatic control tubing, low-pressure fluid distribution, and condensate or drainage routing. The push-in design allows fast field installation without ferrules, compression sleeves, or thread sealant. All three ports share the same 5/16-inch push-in connection size, making the fitting symmetrical and orientation-independent during installation.
Designed as an OEM-style replacement or new-installation fitting for pneumatic control circuits and low-pressure fluid tubing systems using 5/16-inch OD push-in tubing.
Depressurize and isolate the tubing circuit fully before removing or installing any push-in fitting. Ensure tubing ends are cut square and free of burrs before inserting into push-in ports to achieve a proper seal. This fitting is a no-tool connection but requires that tube OD matches the stated 5/16-inch specification exactly. Consult applicable mechanical or HVAC codes for pressure system work in your jurisdiction.
