Introducing the Posi-Stop™
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 does the installer know if the seal is tight enough? It stops spinning. No guesswork, perfect compression every time.
Watch for Posi-Stop in the 573 AutoFill™ Combo, a best-seller across the globe. The union connection between the backflow and pre-adjustable automatic filling valve will have a Posi-Stop seal on both sides. Look for the Posi-Stop sticker on the carton package. Full instructions are also included in the product box for installer instruction notes.
