Value Collection ZMSCS70FDA329 Silicone O-ring Dash 329 10-pack

Product Description

The VALUE COLLECTION ZMSCS70FDA329 is a Dash 329 silicone O-ring with a round cross section, sized at 1.975 inches inside diameter, 2.375 inches outside diameter, and 0.1875 inches thick. Rated at 70 Shore A hardness, this O-ring is manufactured from FDA-compliant silicone material in red, making it suitable for service in food processing, pharmaceutical, and sanitary fluid-handling systems. It is installed by plumbers, pipefitters, and maintenance technicians wherever a reliable static or dynamic face seal is required in applications demanding wide temperature range performance and good dry heat resistance. Sold in a package of 10.

This O-ring is intended for use in systems that encounter oils, chemicals, and solvents, and wherever good weather and ozone resistance is required. Its wide service temperature range of -80 degrees F to 450 degrees F makes it well suited for both low-temperature cold-side piping and high-temperature process or HVAC applications. FDA-compliant silicone construction qualifies it for use in food and beverage equipment, pump seals, valve bodies, and similar sanitary or industrial assemblies. Limited oil resistance should be considered when selecting for heavy petroleum-based fluid service.

Compatibility

Designed as an OEM-style replacement or maintenance stock O-ring for any application requiring a Dash 329 seal with 1.975 inches ID, 2.375 inches OD, and 0.1875 inches thickness in silicone material. Compatible with oils, chemicals, and solvents; verify fluid compatibility before installation in heavy petroleum-based systems due to limited oil resistance.

Installation Notes

O-rings of this type are installed by licensed plumbers, pipefitters, or qualified maintenance technicians. Always depressurize and isolate the system before removing existing seals. Inspect the mating groove for damage, burrs, or contamination prior to seating the new O-ring. Avoid twisting or stretching the O-ring during installation, and apply a compatible lubricant to ease seating and prevent rolling in dynamic applications.
