Value Collection ZMSCS70017 Silicone O-ring Dash 017 50 Pack

Product Description

The VALUE COLLECTION ZMSCS70017 is a Dash 017 silicone O-ring designed for static and dynamic sealing applications across HVAC, plumbing, and industrial systems. It measures 0.688 inches inside diameter, 0.813 inches outside diameter, and 0.0625 inches thick, with a round cross section and a Shore A hardness of 70. The silicone compound delivers reliable performance across an exceptional temperature range of -80 degrees F to 450 degrees F, making it suitable for high-heat and cold-climate installations. Licensed trades and maintenance technicians install this O-ring wherever a standard Dash 017 seal is required.

This O-ring is well suited for applications demanding wide temperature tolerance and dry heat resistance. Common install scenarios include HVAC equipment connections, plumbing fittings, fluid handling assemblies, and equipment subject to weather or ozone exposure. The silicone material offers good weather and ozone resistance and limited compatibility with oils, chemicals, and solvents. It is sold in a 50-piece package, making it practical for service techs stocking a van or completing multiple repairs on a single job.

Installation Notes

Plumbers, HVAC technicians, and industrial maintenance trades install O-rings as part of routine fitting and valve service. Always depressurize and drain the system section before removing an existing seal. Inspect the seating groove for nicks or corrosion that could compromise the new seal. Avoid using petroleum-based lubricants with silicone O-rings; use a silicone-compatible lubricant only.
