PEX cinch clamps are perfect for connecting PEX tubing to brass or poly fittings, especially in hard-to-reach spaces. Stainless steel cinch clamps feature an easy-to-use tab design, so there is no need to get a tool around the entire fitting. Simply press the tab closed with a cinch tool and the connection is complete. The cinch clamp design provides a positive mechanical connection, ensuring the PEX tubing is evenly compressed against the full circumference of the fitting.
