Value Collection ZMSCS70282 Silicone O-ring Dash 282

Product Description

The VALUE COLLECTION ZMSCS70282 is a silicone O-ring with a round cross section, designed for static and dynamic sealing applications across HVAC, plumbing, and industrial fluid systems. It measures 16 inches inside diameter, 16.25 inches outside diameter, and 0.125 inches thick, conforming to Dash 282 sizing. The silicone compound delivers a working temperature range of -80 degrees F to 450 degrees F, making it suitable for applications that demand wide thermal tolerance and reliable dry heat resistance. Hardness is rated at 70 Shore A. This O-ring is installed by licensed plumbers, HVAC technicians, and mechanical contractors in sealing assemblies where high-temperature performance is required.

This O-ring is suited for residential and commercial systems where the sealing point contacts oils, chemicals, or solvents at elevated or depressed temperatures. Typical applications include large-diameter pipe flanges, heat exchanger connections, pump housings, and equipment access covers. Its silicone material provides good weather and ozone resistance, which makes it appropriate for outdoor or exposed mechanical equipment. Note that this compound has limited oil resistance and is not intended for continuous immersion in petroleum-based fluids. Each package contains one O-ring.

Compatibility

Designed as a Dash 282 standard-size replacement O-ring for large-diameter sealing applications in HVAC, plumbing, and industrial mechanical systems requiring silicone elastomer material.

Installation Notes

Installation is typically performed by licensed plumbers or HVAC technicians following applicable IPC or IFGC service procedures. Shut down and depressurize the system fully before removing the existing O-ring. Inspect the groove and mating surfaces for nicks, corrosion, or debris before seating the new O-ring. Do not use petroleum-based lubricants with silicone O-rings; use a silicone-compatible assembly lubricant if needed.
