Featuring patented design that helps minimize kinking or crimping, Speedi Plumb® PLUS Polymer Braid Connector resists corrosion from most household cleaning products. ProCoat® Coated Stainless Steel Connector, providing ¾ in. full flow internal diameter, resists most harsh chemicals that can cause pinhole leaks. Both push connect units have pre-inserted tube stiffener that aligns with connector tubing to produce watertight seal, and are compatible with copper, PEX, and CPVC connections.
