Value Collection ZMSCS70015 Silicone O-ring Dash 015 100pk

Product Description

The VALUE COLLECTION ZMSCS70015 is a Dash 015 silicone O-ring designed for sealing applications that demand a wide operating temperature range and reliable resistance to dry heat, weather, and ozone. The ring measures 0.563 inches inside diameter, 0.688 inches outside diameter, and 0.0625 inches (1/16 inch) thick, with a round cross section and a Shore A hardness rating of 70. White silicone construction gives this O-ring strong performance across a temperature range of -80 degrees F to 450 degrees F. It is sold in packages of 100 and is suited for installation by licensed plumbers, HVAC technicians, and mechanical contractors.

This O-ring is used in fluid and gas sealing applications where exposure to wide temperature swings, dry heat, ozone, and certain chemicals or solvents is expected. Typical use cases include pump seals, valve seats, pipe unions, and equipment fittings in residential and light commercial mechanical systems. Its limited oil resistance should be noted when selecting for petroleum-fluid service. The 100-piece pack suits service vans and shop stock for ongoing maintenance and repair work.

Installation Notes

Installation is typically performed by licensed plumbers, HVAC technicians, or mechanical contractors. Shut off and depressurize the system completely before removing the old O-ring and seating the replacement. Inspect the groove for burrs or damage that could compromise the seal. Do not overstretch the O-ring during installation, and avoid using petroleum-based lubricants given the limited oil resistance of silicone material.
