O-Rings for the Check Valve on the Ondine Thermostatic Valve 25072

Our Item 10282 - Ondine Thermostatic Valve Replacement Cartridge and Rebuild Kit includes the thermostatic cartridge with o-rings pre-installed as well as the two o-rings that fit into the oval shaped grooves of the Ondine valve cover plate. We do not currently include the o-rings for the check-valves, but they are relatively easy to find at your local plumbing supply store.

The O-rings used on the Check/Stop Valves of the Ondine Thermostatic Valve Models 25072 (3/4 inch) and the 25071 (1/2 inch) are -113 HEAT RESISTANT (.549±.007 ID x .103±.003 CS inches) and -117 (.799±.010 ID x .103±.003 CS inches). VASELINE and other petroleum greases tend to attack rubber and reduce the life of o-rings. Use Silicone Grease instead.
