The VALUE COLLECTION ZMSCS70317 is a silicone O-ring with a round cross section, rated at 70 durometer hardness, and sized to Dash 317 dimensions. The inside diameter measures 0.912 inches, the outside diameter measures 1.313 inches, and the cross-section thickness is 0.1875 inches (3/16 inches). Built from white silicone compound, this O-ring handles extreme temperature swings, rated from -80 degrees F to 450 degrees F. It delivers good dry heat resistance, weather resistance, and ozone resistance. This part is sold in packages of 10 and weighs 0.02 pounds per package. Plumbers, HVAC technicians, and industrial maintenance professionals commonly install this type of sealing component.
This O-ring is suited for static and dynamic sealing applications that demand a wide operating temperature range. Silicone compound makes it a reliable choice for exposure to certain chemicals, solvents, and light oil contact, though oil resistance is limited. Typical applications include HVAC equipment seals, fluid system connections, pump housings, and general mechanical assemblies where thermal cycling is a concern. The Dash 317 designation follows AS568 standard sizing, making this a recognized dimension in sealing specifications across residential and light commercial systems.
Designed as a standard Dash 317 silicone O-ring for use in HVAC, plumbing, and general industrial sealing applications requiring AS568 Dash 317 dimensional fitment.
Installation should be performed by a licensed technician or qualified maintenance professional. Always depressurize and de-energize the system before replacing any sealing component. Inspect the mating groove and seating surface for damage, burrs, or contamination before installing the new O-ring. Avoid twisting or overstretching the O-ring during installation, and use only a compatible lubricant if lubrication is required.
