Caleffi Posi-Stop Advanced Union Seal

June 15, 2023
Caleffi Posi-Stop Advanced Union Seal 2.jpg

Caleffi’s advanced technology named Posi-Stop incorporates an embedded O-ring into a product's union connection. The contractor tightens the union nut down until a positive, metal-to-metal stop is reached. 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. This results in reducing the number of costly callbacks while conserving company resources.
