The ultimate in pipe connection flexibility.Suitable for pipe with outside diameter from 1.06 in. to 1.34 in. (27 - 34mm).Coupling accepts following pipe:1 in. PEX1 in. CTS Polyethylene1 in. Copper3/4 in. and 1 in. PVC3/4 in. and 1 in. IPS OD PE3/4 in. Lead3/4 in. and 1 in. ABS3/4 in. and 1 in. Galvanized3/4 in. and 1 in. Stainless SteelFlexible connections - Designed to fit a wide range of different diameters on most materials.Easier and faster to install - Simply witness mark the pipe against the flange on the fitting and then insert the pipe to the correct depth.No special tools are needed. The nut can be tightened using a wrench.No scrap value unlike brass fittings.Lasts longer - Made from advanced thermoplastic materials. Corrosion-resistant, ensuring a long service life (50+ year design life*).Safety - Composite construction means there is no leaching of heavy metals. No cuts (no sharp edges).Applications - used extensively for repair work, new installations and upgrades.
