Posi-Stop™ - A Superior Union Seal
Caleffi North America, Inc., a leader in state-of-the-art engineered solutions for hydronic and plumbing systems, is pleased to announce an advanced technology named Posi-Stop™ that incorporates an embedded O-ring into a product’s union connection. This advanced design results in a consistent and superior seal over the broad range of conditions encountered in plumbing and hydronic applications, streamlining installation and service.
When the contractor tightens the union nut, an EPDM O-ring seal compresses to a controlled value by way of a positive metal-to-metal stop. This controls the O-ring compression to a precise, repeatable value. The result? A field proven, reliable seal connection - valve, after valve, after valve, after valve.
Posi-Stop simplifies serviceability. The installer can remove, service, and reinstall the valve with the SAME union connections, optimizing service trips. The embedded O-ring provides a reliable seal to liquid and air, allowing contractors to pneumatically test systems with air in order to identify leaks before putting the system into operation.
To identify a product utilizing the Posi-Stop union connection, look for the Posi-Stop name on the product box. For more information, please call us at (414) 238-2360.
