Value Collection ZMSCS70142 Silicone O-ring Dash 142 10-pack

Product Description

The VALUE COLLECTION ZMSCS70142 is a round-cross-section silicone O-ring sized to the Dash 142 standard, with a 2.375-inch inside diameter, a 2.563-inch outside diameter, and a 0.094-inch thickness. Rated at 70 durometer (hard), this O-ring is formulated for applications that demand a wide service temperature range, spanning -80 degrees F to 450 degrees F. Its silicone compound provides good dry heat resistance and strong resistance to weathering and ozone. HVAC technicians, plumbers, and equipment maintenance professionals use this O-ring as a sealing element in fluid-handling and mechanical assemblies. Sold in a package of 10.

This O-ring is suited for residential and commercial applications where sealing against oils, certain chemicals, and solvents is required. The wide temperature tolerance makes it appropriate for use in HVAC equipment, pool and spa plumbing, and general mechanical systems exposed to outdoor conditions or elevated heat. It is not recommended for systems with sustained heavy oil exposure. Each unit in the package meets the Dash 142 dimensional standard, allowing straightforward drop-in use wherever that dash size is specified.

Installation Notes

Shut down and de-pressurize the system fully before replacing any O-ring seal. Inspect the seating groove for nicks, corrosion, or debris that could prevent a proper seal or damage the new ring. Lubricate the O-ring with a compatible lubricant before installation to ease seating and reduce the risk of tearing during assembly. Follow applicable plumbing or mechanical codes for the system type being serviced.
