Value Collection ZMSCS70013 Silicone O-ring Dash 013

Product Description

The VALUE COLLECTION ZMSCS70013 is a silicone O-ring with a round cross section, engineered for sealing applications that demand wide temperature tolerance and reliable dry heat resistance. Rated at 70 Shore A hardness, this ring fits Dash 013 groove dimensions with a 0.438-inch inside diameter, 0.563-inch outside diameter, and a 0.0625-inch (1/16 inch) cross-section thickness. The white silicone compound handles continuous service from -80 degrees F to 450 degrees F, making it well suited for HVAC, plumbing, pool, and general mechanical assemblies where standard rubber compounds fall short. Licensed HVAC technicians, plumbers, and pool service professionals routinely specify silicone rings in high-temperature or ozone-exposed environments.

This O-ring is appropriate for residential and light commercial systems where sealing integrity must hold across broad thermal cycles. It performs well in dry heat, outdoor weathering, and ozone exposure. Compatibility extends to oils, certain chemicals, and solvents, though the formulation carries limited oil resistance — a factor to weigh in heavy petroleum or hydraulic applications. Sold in a package quantity of 100, the ZMSCS70013 suits shop-stock replenishment, fleet service kits, and maintenance accounts that require consistent dimensional availability.

Compatibility

Designed for Dash 013 O-ring groove applications across HVAC, plumbing, pool, and general mechanical equipment requiring a silicone compound with broad temperature range capability.

Installation Notes

O-ring installation should be performed by a qualified technician following the equipment manufacturer's assembly procedures. Shut off and relieve system pressure before removing or replacing any sealing component. Inspect the groove and mating surfaces for nicks, burrs, or debris before seating the ring. Avoid twisting or rolling the O-ring during installation, as spiral distortion leads to premature seal failure.
