Value Collection ZMSCS70124 Silicone O-ring Dash 124 25-pack

Product Description

The VALUE COLLECTION ZMSCS70124 is a Dash 124 silicone o-ring with a round cross section, rated at 70 durometer hardness. It measures 1.25 inches inside diameter, 1.438 inches outside diameter, and 0.0937 inches thick. Silicone construction provides a wide operating temperature range of -80 degrees F to 450 degrees F, along with good dry heat resistance and ozone resistance. This o-ring is installed by licensed plumbers, HVAC technicians, and mechanical contractors in sealing applications where temperature extremes are a primary concern. Each package contains 25 pieces.

This o-ring is suited for static and low-dynamic sealing applications in plumbing, HVAC, and general mechanical systems where silicone is specified. The Dash 124 designation makes it a standard cross-reference size recognized across trade catalogs. It performs well in environments exposed to ozone, weathering, and dry heat cycles. Note that silicone offers limited oil resistance; it is not the preferred choice for direct petroleum oil immersion service. Verify that silicone material is compatible with the fluid or media in the application before installation.

Installation Notes

Shut off fluid supply and relieve system pressure before removing or replacing any o-ring. Inspect the groove and mating surfaces for nicks, corrosion, or debris that could compromise the seal. Do not stretch the o-ring beyond the required installation size, and avoid using sharp tools that could nick the sealing surface. Silicone o-rings are not recommended for petroleum oil immersion service; confirm fluid compatibility before installation.
