The VALUE COLLECTION ZMSCS70012 is a round cross-section silicone O-ring conforming to Dash 012 dimensions. It measures 0.375 inches inside diameter, 0.500 inches outside diameter, and 0.0625 inches thick. Rated at 70 Shore A hardness, this O-ring is engineered for applications that demand a wide operating temperature range, spanning -80 degrees F to 450 degrees F. It offers good dry heat resistance along with solid weather and ozone resistance. Plumbers, HVAC technicians, and industrial maintenance professionals install these seals in fluid and gas connection points where standard rubber compounds would degrade under thermal or environmental stress.
This O-ring is suited for static and dynamic sealing applications in residential and commercial systems, including plumbing fittings, HVAC equipment, pneumatic assemblies, and chemical handling lines. The silicone compound tolerates exposure to oils, chemicals, and solvents within its rated limits, though users should note that oil resistance is limited compared to nitrile alternatives. Sold in a package quantity of 100, this SKU is practical for service shops and technicians maintaining an O-ring inventory across multiple call types.
Designed as an OEM-style replacement silicone O-ring for plumbing, HVAC, pneumatic, and chemical handling assemblies requiring a Dash 012 dimension seal in silicone compound.
Installation is typically performed by licensed plumbers, HVAC technicians, or industrial maintenance mechanics. Shut off fluid or gas supply and relieve system pressure before replacing any O-ring. Clean the seating groove and mating surfaces thoroughly before installation to prevent leaks or premature seal failure. Do not roll or twist the O-ring during installation, and avoid using sharp tools that could nick the sealing surface.
