Value Collection ZMSCS70110 Silicone O-ring Dash 110

Product Description

The VALUE COLLECTION ZMSCS70110 is a silicone o-ring with a round cross section, designed for static and dynamic sealing applications across a wide operating temperature range. It measures 0.375 inches inside diameter, 0.563 inches outside diameter, and 0.094 inches thick, conforming to Dash 110 sizing. The silicone compound delivers good dry heat resistance and strong resistance to weathering and ozone, making it a reliable choice for HVAC, plumbing, and general mechanical sealing work. Licensed technicians and maintenance professionals reach for silicone o-rings when standard nitrile compounds fall short of temperature demands.

This o-ring suits residential and commercial applications where seals must perform across a broad temperature range from -80 degrees F to 450 degrees F. Typical uses include HVAC equipment sealing points, fluid system connections, and enclosure gasket applications where ozone and weather exposure are concerns. It carries a hard durometer rating of 70 Shore A. Note that oil resistance is limited, so verify compatibility before installing in high-oil-content fluid circuits. Sold in a package quantity of 100 units, this o-ring is suited for service shops and technicians maintaining inventory of common seal sizes.

Compatibility

Designed as an OEM-style replacement or service seal for any application requiring a Dash 110 silicone o-ring with a round cross section. Compatible with oils, chemicals, and solvents as noted; limited oil resistance should be verified against the specific fluid chemistry before installation.

Installation Notes

Silicone o-rings are installed by HVAC technicians, plumbers, and general mechanical service professionals. Always de-energize equipment and relieve system pressure before replacing any seal. Lubricate the o-ring with a compatible silicone-based lubricant to ease installation and prevent tearing during assembly. Avoid over-stretching the o-ring during placement, as silicone has lower tensile strength than nitrile compounds.
