Value Collection ZMSCS70209 Silicone O-ring Dash 209 50pk

Product Description

The VALUE COLLECTION ZMSCS70209 is a Dash 209 silicone O-ring with a round cross section, designed for static and dynamic sealing in fluid and pneumatic systems. It measures 0.688 inches inside diameter, 0.938 inches outside diameter, and 0.125 inches thick. The white silicone compound is rated for continuous service from -80 degrees F to 450 degrees F, making it well suited for applications that demand a wide operating temperature range and good dry heat resistance. Licensed plumbers, HVAC technicians, and industrial maintenance trades install this O-ring wherever a reliable, temperature-stable seal is required.

This O-ring is used in residential and commercial plumbing, HVAC refrigerant and fluid lines, pool and spa equipment, and general industrial assemblies where exposure to ozone, weathering, and moderate chemical contact is expected. The silicone material offers good resistance to oils, certain chemicals, and solvents, making it a practical choice for multi-service environments. It is sold in a package of 50, which suits service technicians who carry standard dash-size inventory on their trucks.

Installation Notes

Power down or de-energize the associated system and relieve all fluid or pneumatic pressure before removing the old O-ring. Inspect the groove for burrs, scoring, or contamination and clean thoroughly before seating the new O-ring. Lubricate the O-ring with a compatible, silicone-safe lubricant to ease installation and reduce the risk of tearing. Follow applicable trade codes and manufacturer service procedures when reinstalling fittings or closures.
