Value Collection ZMSCS70105 Silicone O-ring Dash 105 Pack 100

Product Description

The VALUE COLLECTION ZMSCS70105 is a Dash 105 silicone O-ring designed for static and dynamic sealing applications across a broad range of operating conditions. The ring measures 0.156 inches inside diameter, 0.344 inches outside diameter, and 0.094 inches thick, with a round cross section. Rated at 70 Shore A hardness, it handles temperatures from -80 degrees F to 450 degrees F, making it well suited for systems that cycle through extreme heat or cold. Plumbers, HVAC technicians, and industrial maintenance professionals use this O-ring where standard rubber compounds fall short on temperature range or ozone exposure.

This O-ring fits sealing applications that demand good dry heat resistance and reliable performance against weather and ozone degradation. It is commonly installed in fluid line fittings, valve stems, pump housings, and equipment exposed to outdoor or high-temperature environments. Note that silicone carries limited resistance to petroleum-based oils, so confirm fluid compatibility before installation. This listing is sold as a package of 100 rings, making it appropriate for service technicians who stock consumables in bulk.

Compatibility

Designed as a standard Dash 105 O-ring replacement for any application calling for a silicone compound seal at those dimensions. Verify fluid and pressure compatibility with silicone material properties before installation.

Installation Notes

Licensed plumbers and HVAC technicians typically install O-rings of this type during valve, fitting, or pump service. Shut off system pressure and drain the line before removing the old seal. Lightly lubricate the O-ring with a compatible, silicone-safe grease to ease seating and reduce risk of pinching or rolling during assembly. Avoid petroleum-based lubricants, which can degrade silicone over time.
