The 3/4 in. Tectite by Apollo Push-To-Connect x Push-To-Connect x Female Pipe Thread Tee is the fastest, cleanest and simplest way to join any combination of copper, CPVC, PE-RT and PEX pipe without the use of tools, solder, open flame or glue. The female threaded outlet is ideal for the installation of thermal expansion tanks. Simply insert the pipe to allow the high-strength stainless steel teeth to grip the pipe securely against the specially designed O-ring. Fitting removal and reuse is just as simple using a simple demount clip (sold separately). After assembly, fittings may be rotated for simpler installation in tight spaces. All Tectite by Apollo fittings are approved for use in both potable water and hydronic heating piping systems. Color: Brass.
