Value Collection ZMSCS70011 Silicone O-ring Dash 011 100pk

Product Description

The VALUE COLLECTION ZMSCS70011 is a round cross-section silicone O-ring sized to Dash 011 standards, with a 0.313-inch inside diameter, 0.438-inch outside diameter, and 0.0625-inch (1/16 inch) wall thickness. Rated for service from -80 degrees F to 450 degrees F, this O-ring is built for applications that demand a wide temperature range and reliable dry heat resistance. The 70-durometer hardness provides a firm, stable seal under compression. HVAC technicians, plumbers, and mechanical contractors use O-rings of this type to seal fittings, valves, and fluid connections in both new construction and service work.

This O-ring is suited for residential and light commercial applications where good weather resistance and ozone resistance are required. The silicone compound also offers limited oil resistance and performs well in environments with exposure to certain chemicals and solvents. Typical install scenarios include sealing around valve stems, sensor ports, and threaded fittings in HVAC systems, plumbing assemblies, and fluid-handling equipment. Each package contains 100 O-rings, making this pack a practical shop or truck-stock option for technicians who replace seals during routine service calls.

Compatibility

Designed as a standard Dash 011 silicone O-ring for use in valves, fittings, and fluid-handling components that require a wide-temperature-range elastomeric seal in HVAC, plumbing, and mechanical systems.

Installation Notes

O-rings of this type are installed by licensed HVAC technicians, plumbers, or journeyman mechanics during valve, fitting, or component service. De-energize the system and relieve all pressure before removing any fitting or valve that contains an O-ring seal. Inspect the seating groove for nicks or debris before installing the replacement O-ring, and avoid twisting or stretching the O-ring during installation. Silicone O-rings are generally not compatible with petroleum-based lubricants; use a silicone-based assembly lubricant where a lubricant is required.
