Access the branch pipe bolted mechanical pipe fittings, mechanical tee, Stone is an innovative pipe connection system. No soldering directly connected from the charge of the branch pipe.
The way to pick up the drilled hole on the head of the branch pipe, factory equipped with a drilling machine, and the smooth surface of export to the assembly ring fittings to enable the flow to ensure maximum, while reducing the pipeline of local resistance, assigned to the washer.
