Value Collection ZMSCS70102 Silicone O-ring Dash 102 25 Pack

Product Description

The VALUE COLLECTION ZMSCS70102 is a Dash 102 silicone o-ring with a round cross section, packaged in quantities of 25. It measures 0.0625 inches inside diameter, 0.2500 inches outside diameter, and 0.0937 inches thick. The silicone compound is rated for a wide service temperature range of -80 degrees F to 450 degrees F, making it suitable for applications that demand good dry heat resistance and weather and ozone resistance. Shore hardness is 70, placing it in the hard range. Plumbers, HVAC technicians, and maintenance professionals use this o-ring where a reliable, compact face or radial seal is required in high-temperature or outdoor-exposed environments.

This o-ring is used in residential and light commercial applications where silicone elastomers outperform standard nitrile or EPDM compounds. Typical install scenarios include sealing ports on HVAC components, fluid fittings, and pneumatic or hydraulic connections that cycle through wide temperature swings. Its limited oil resistance means it is best suited for dry heat, water, steam, and ozone-exposed service rather than petroleum-fluid environments. The 25-piece package supports bench stock and service van inventory for techs who encounter this size frequently.

• Good weather and ozone resistance for outdoor or exposed installations
• White silicone material suitable for non-oil, non-petroleum service environments
• Packaged 25 pieces per unit for bench stock and service van replenishment

Compatibility

Designed as a standard Dash 102 o-ring replacement for any application specifying a 0.0625 inch ID by 0.2500 inch OD by 0.0937 inch thick round cross section silicone seal.

Installation Notes

Installation is typically performed by licensed HVAC technicians, plumbers, or qualified maintenance personnel. Always depressurize and isolate the system before removing or installing o-rings to prevent injury and ensure a proper seal. Inspect the groove and mating surfaces for nicks or contamination before seating the new o-ring. Because this compound has limited oil resistance, confirm the service fluid is compatible with silicone elastomers before installation.
