Also known as pipe clamp or key clamp, AusClamp fittings are made from Malleable Cast Iron. All are finished with a Hot Dipped Galvanised coating and the Set Screw is machined from Stainless Steel. Sizes are based on the diameter of pipe being used, for example, a 20 Nominal Bore fitting is used to suit 20 Nominal Bore pipe (or any circular section up to 27mm across). The Clamp-on Tee is useful in applications where sliding the fitting onto the end of the pipe section is unachievable. This Tee can be installed mid-span.
