NEW radiant & hydronic PRODUCTS

the latest products to hit the Radiant & hydronic market so far in 2023.

Union connection

The Posi-Stop incorporates an embedded O-ring into a product's union connection. This advanced design results in a superior seal, period, the company says. When the union nut is tightened, an EPDM O-ring seal compresses to a precise value with a positive metal-to-metal stop. The result? A field-proven, reliable seal connection. Posi-Stop simplifies serviceability. Remove, service, and reinstall the valve with the SAME union connections. Pneumatically test systems with air to identify leaks before putting the system into operation. Look for the Posi-Stop logo on Caleffi products.
