Value Collection ZMSCS70FDA008 Silicone O-ring Dash 008 100 Pack

Product Description

The VALUE COLLECTION ZMSCS70FDA008 is a Dash 008 silicone O-ring with a 0.188-inch inside diameter, 0.312-inch outside diameter, and a 0.0625-inch (1/16 inch) round cross section. Molded from 70-durometer red silicone with FDA-compliant material, this O-ring is engineered for applications that demand a wide service temperature range, from -80 degrees F to 450 degrees F. The silicone compound provides good dry heat resistance and strong weather and ozone resistance, making it a reliable sealing solution across HVAC, plumbing, pool, and light chemical-handling systems. Licensed technicians and plumbers install these O-rings as sealing elements in fluid and gas connections, valve bodies, and fittings.

This O-ring is suited for use in residential and light commercial systems where elevated temperature exposure, outdoor weathering, or ozone contact is a factor. Common install scenarios include HVAC refrigerant-side fittings, potable-water plumbing components requiring FDA-compliant materials, pool and spa equipment, and industrial fluid-handling assemblies. Limited oil resistance should be factored into the application review before installation. Supplied in a package quantity of 100 pieces, making it practical for service technicians stocking a van or shop inventory.

• Wide temperature service range: -80 degrees F to 450 degrees F
• 70 Shore A hardness (Hard rating) for firm sealing under compression
• Round cross section for consistent seating in standard O-ring grooves
• Good weather and ozone resistance for outdoor or exposed-system use
• Packaged as 100-piece quantity — practical for multi-job van stock

Compatibility

Designed as a standard Dash 008 O-ring replacement for any groove or fitting requiring a 0.188-inch ID, 0.312-inch OD, and 0.0625-inch cross section in silicone material. Compatible with oils, chemicals, and solvents as noted; verify oil compatibility against specific fluid exposure before use.

Installation Notes

Installation is performed by licensed plumbers, HVAC technicians, or pool service professionals. Always depressurize and shut off fluid supply to the system before removing or installing O-rings. Inspect the groove for nicks, burrs, or debris that could compromise the seal. Do not stretch the O-ring beyond the manufacturer groove specification, and apply only a compatible lubricant to ease installation without degrading the silicone compound.
