Grooved-End Iron Pipe Fittings
The grooved ends on these fittings connect to pipe with a clamp to easily install piping systems. Since there’s no heat or threading required, they provide quick access to a pipe line for routine maintenance. Fittings are also known as Victaulic fittings. They are for use in noncorrosive applications.
Clamps have a two-piece housing that can remain intact for installation.
Inline tees are also known as branch tees.
