Value Collection ZMSCS70016 Silicone O-ring Dash 016 100-pack

Product Description

The VALUE COLLECTION ZMSCS70016 is a silicone O-ring with a round cross section, sized to Dash 016 specifications. It measures 0.625 inches inside diameter, 0.750 inches outside diameter, and 0.0625 inches thick. With a Shore hardness of 70 and a working temperature range of -80 degrees F to 450 degrees F, this O-ring is built for applications that demand wide thermal tolerance and reliable dry heat resistance. It also offers good resistance to weather and ozone. Plumbers, HVAC technicians, and industrial maintenance trades install this type of seal in fluid and gas system connections where a durable, flexible seal is required. Sold in a package of 100.

This O-ring is suited for residential and commercial applications where sealing against oils, chemicals, and solvents is needed. Its silicone compound performs consistently across a broad temperature range, making it a practical choice for HVAC refrigerant line fittings, plumbing connections, and mechanical assemblies exposed to outdoor elements or high-heat environments. Note that oil resistance is limited compared to nitrile compounds, so verify compatibility with the specific fluid or gas present in the system before installation.

Key Features

• Compatible with oils, chemicals, and solvents; limited oil resistance — verify suitability

Compatibility

Designed as a standard Dash 016 silicone O-ring for use in fluid and gas sealing applications across HVAC, plumbing, and industrial mechanical systems where silicone elastomer is the specified material.

Installation Notes

Licensed plumbers, HVAC technicians, and mechanical tradespeople typically install O-rings of this type during assembly or service of valves, fittings, and manifold connections. Always depressurize and isolate the system before removing or installing any O-ring seal. Inspect the seating surface for nicks, scoring, or debris before installation to ensure a leak-free seal. Do not use petroleum-based lubricants with silicone O-rings unless confirmed compatible with the system fluid.
