Value Collection ZMSCS70141 Silicone O-ring Dash 141

Product Description

The VALUE COLLECTION ZMSCS70141 is a Dash 141 silicone O-ring designed for static and dynamic sealing applications across HVAC, plumbing, and industrial systems. It measures 2.313 inches inside diameter, 2.500 inches outside diameter, and 0.094 inches (3/32 inches) thick, with a round cross section and a Shore A hardness of 70. The silicone compound supports a working temperature range of -80 degrees F to 450 degrees F, making it suitable for applications that demand wide thermal tolerance and dry heat resistance. Each package contains 10 rings. Plumbers, HVAC technicians, and mechanical contractors install these rings where a reliable, repeatable seal is required.

This O-ring is used in residential and commercial systems where the sealing surface is exposed to moderate oil contact, chemicals, solvents, weather, or ozone. Typical applications include pump housings, valve bodies, manifold connections, and equipment access covers in HVAC equipment, plumbing assemblies, and general mechanical systems. The white silicone color aids visual inspection during service. Its broad temperature range makes it a common choice for outdoor or high-heat enclosures where standard EPDM or Buna-N compounds fall short.

Compatibility

Designed as an OEM-style replacement or service spare for any application requiring a Dash 141 silicone O-ring with a 2.313 inches inside diameter and 2.500 inches outside diameter. Compatible with oils, chemicals, and solvents as noted by the manufacturer; verify chemical compatibility with specific media before installation.

Installation Notes

Installation is typically performed by licensed plumbers, HVAC technicians, or mechanical contractors. De-energize or shut off the system and relieve all pressure before removing or replacing any O-ring. Inspect the mating groove and sealing surface for nicks, corrosion, or debris before seating the new ring. Avoid twisting or rolling the O-ring during installation, and use only lubricants known to be compatible with silicone compounds.
