Value Collection ZMSCS70028 Silicone O-ring Dash 028 50pk

Product Description

The VALUE COLLECTION ZMSCS70028 is a silicone O-ring with a round cross section, sized at 1.375 inches inside diameter, 1.5 inches outside diameter, and 0.0625 inches thick, corresponding to Dash 028. It is sold in a pack of 50. This O-ring is designed for static and dynamic sealing applications across HVAC, plumbing, and general mechanical systems. Silicone compound gives it a wide serviceable temperature range of -80 degrees F to 450 degrees F, along with good dry heat resistance and weather and ozone resistance. Installation is performed by HVAC technicians, plumbers, and maintenance mechanics as part of routine seal replacement or new assembly work.

This O-ring suits applications that demand wide temperature tolerance and exposure to outdoor or high-heat environments. It is appropriate for use with oils, chemicals, and solvents within its rated compatibility range, though oil resistance is limited. Typical install scenarios include shaft seals, port seals, face seals, and fitting connections in residential and light commercial HVAC equipment, fluid handling assemblies, and general industrial machinery. The pack-of-50 quantity supports service technicians who replace O-rings in volume during scheduled maintenance.

Installation Notes

De-energize and depressurize any system before replacing O-rings. Inspect the groove and mating surfaces for damage or contamination before seating the new seal. Avoid stretching the O-ring beyond its elasticity limits during installation, and do not use sharp tools that may nick or cut the seal. Follow applicable codes such as IFGC or IPC for gas and plumbing system seals where required.
