The GRINNELL Mechanical Tees provide an additional threaded or grooved outlet in existing piping. For new construction, Mechanical Tees provide a way to bypass the use of a reducing tee. The Mechanical Tee can easily be converted to a cross.
Approvals
UL, FM, ULC, VdS,
LPCB (Cert. Nos. 669a and 673a)
Branch Outlet
Threaded (Female NPT or ISO 7-1)
Grooved
Max. Working Pressure
500 psi (34,5 Bar)
Note: Maximum pressure applies to
the Mechanical Tee. When connected
to a grooved coupling, the rating will
be the lesser of the Mechanical Tee or
Coupling rating. Maximum pressure is
a total from all loads, based on standard weight steel pipe. For further information on piping specifications contact GRINNELL Mechanical Services.
