The Posi-Stop Union Seal Technology

What is Posi-Stop™? Caleffi is rolling out a union seal design for a consistent and superior seal over the broad range of connections encountered in plumbing and hydronic applications. This versatile system uses an EPDM O-ring, in place of a fiber gasket.

When the installer tightens the union nut, an O-ring seal compresses to a controlled value by way of a positive metal-to-metal stop. How do you know if it is tight enough? It stops spinning. No guesswork, enjoy perfect compression every time!
