Value Collection ZMSCS70031 Silicone O-ring Dash 031

Product Description

The VALUE COLLECTION ZMSCS70031 is a silicone O-ring designed for static and dynamic sealing applications across HVAC, plumbing, and industrial systems. With a 1.75-inch inside diameter, 1.875-inch outside diameter, and a 0.0625-inch round cross section, this Dash 031 O-ring provides a consistent seal in assemblies where dimensional precision matters. The silicone compound gives it a wide usable temperature range of -80 degrees F to 450 degrees F, making it suitable for both low-temperature exposure and sustained dry heat conditions. Hardness is rated at 70 Shore A. Installers and technicians working in environments with temperature swings, ozone exposure, or weathering demand will find this compound appropriate for the task.

This O-ring is used in residential and light commercial HVAC equipment, plumbing fittings, pump housings, valve bodies, and chemical handling assemblies where a reliable face or groove seal is required. The silicone material offers good compatibility with oils, certain chemicals, and solvents, though oil resistance is limited and should be evaluated against the specific application. Each order package contains 25 O-rings, allowing technicians to stock a useful quantity for service calls or production line use.

Installation Notes

Installation of O-rings should be performed by a qualified technician familiar with the sealing assembly. De-energize, depressurize, and drain the system before replacing any O-ring. Inspect the groove and mating surfaces for nicks or burrs that could damage the new seal. Avoid using petroleum-based lubricants with silicone O-rings unless confirmed compatible with the compound and the media being sealed.
