Victaulic Shouldered Systems benefits: Installation-Ready™ Couplings will improve installation productivity – up to 10 times faster! System design flexibility Allows for expansion, contraction & deflection of the piping system Ideal for abrasive applications Zero leak path for compressed air systems Shouldered couplings mechanically lock shouldered pipe ends together in a safe and secure manner. They cannot blow off under pressure or pull off under vibration because the couplings' shoulder sections engage the whole circumference of the pipe shoulders. These shouldered joining systems are ideal for use in mining, cement, and concrete industries.
