Parker 364PTC-4 Push-to-connect Union Tee 1/4 Inch Od

Product Description

The PARKER 364PTC-4 is a push-to-connect union tee tube fitting designed for joining three tube runs at a single junction without tools or ferrules. Built from composite material with a nitrile O-ring seal, it accepts 1/4-inch OD tubing on all three ports. The fitting is rated to 250 psi, making it suitable for a range of fluid and pneumatic line applications in HVAC, refrigeration, and plumbing support systems. Installation requires no wrenches — tubing inserts directly and locks in place, reducing labor time during rough-in or service work.

This fitting is used in residential and light commercial applications wherever a three-way tube junction is needed on 1/4-inch OD tubing runs. Typical scenarios include condensate drain line splits, pneumatic control tubing branches, and fluid transfer lines in equipment utility areas. The composite body resists corrosion and is well suited for indoor environments where metal fittings may be unnecessary. HVAC technicians and plumbers commonly use this type of fitting when routing small-diameter tubing through tight equipment compartments.

Key Features

• Push-to-connect design — no tools, ferrules, or thread sealant required for installation
• Composite body construction resists corrosion in indoor service environments
• Nitrile O-ring seal provides reliable fluid and air containment
• Rated to 250 psi for use in moderate-pressure pneumatic and fluid lines
• Accepts 1/4-inch OD tubing on all three ports for a true union tee configuration

Compatibility

Designed as an OEM-style push-to-connect replacement or new-installation fitting for systems using 1/4-inch OD tubing in pneumatic, fluid transfer, or HVAC auxiliary line applications.

Installation Notes

Shut off system pressure and depressurize the line before removing or installing any push-to-connect fitting. Ensure tubing ends are cut cleanly and squarely — deformed or burred tube ends will compromise the O-ring seal and can cause leaks under pressure. To disconnect, depress the release collar evenly around the tubing before pulling the tube free. This fitting is typically installed by licensed HVAC technicians or plumbers; follow applicable local mechanical codes for small-bore tubing connections.
