Value Collection ZMSCS70027 Silicone O-ring Dash 027 50pk

Product Description

The VALUE COLLECTION ZMSCS70027 is a silicone O-ring sold in a pack of 50, designed for static and dynamic sealing applications across HVAC, plumbing, and general industrial systems. With a 1.313-inch inside diameter, 1.438-inch outside diameter, and 0.0625-inch thickness, this Dash 027 O-ring features a round cross section and a Shore hardness of 70. Silicone construction gives it a wide service temperature range, from -80 degrees F to 450 degrees F, making it a practical choice for high-heat and cold-environment sealing tasks. Licensed tradespeople and maintenance technicians install these in equipment that sees thermal cycling, ozone exposure, or dry heat conditions.

This O-ring is suited for residential and commercial applications where wide temperature tolerance is required. Typical uses include sealing joints in HVAC equipment, plumbing fittings, and light industrial assemblies exposed to chemicals, solvents, or weathering. The silicone material offers good weather and ozone resistance, along with limited oil resistance. It is not recommended as a primary seal in high-oil-concentration environments. The 50-piece pack is appropriate for service technicians stocking common seal sizes for field repairs or scheduled maintenance.

Installation Notes

O-ring installation is performed by HVAC technicians, plumbers, and maintenance mechanics. Always depressurize the system and shut off fluid supply before replacing any seal. Inspect the groove for burrs or surface damage before seating the new O-ring. Avoid twisting the ring during installation, as a twisted O-ring will not seal correctly and may fail prematurely.
