Value Collection ZMSCS70116 Silicone O-ring Dash 116 100pk

Product Description

The VALUE COLLECTION ZMSCS70116 is a silicone O-ring with a round cross section, designed for static and dynamic sealing applications across a wide temperature range. With a 0.75 inch inside diameter, 0.938 inch outside diameter, and 0.094 inch thickness, this is a standard Dash 116 size. The 70 durometer hardness rating places it in the hard category, giving it good dimensional stability under compression. Silicone construction provides reliable performance from -80 degrees F to 450 degrees F, making it a strong choice where dry heat resistance or outdoor exposure is a factor. Each package contains 100 pieces.

This O-ring is suited for use in HVAC, plumbing, pool equipment, and general industrial applications where sealing against oils, chemicals, and solvents is required at extended temperature ranges. The silicone compound offers good resistance to weathering and ozone degradation, making it appropriate for outdoor or exposed mechanical assemblies. It is not recommended for applications requiring high oil immersion resistance. Licensed tradespeople and maintenance technicians commonly use Dash 116 O-rings as replacements in valve stems, pump housings, fittings, and fluid connectors.

Installation Notes

O-ring replacement should be performed by a qualified technician after depressurizing and isolating the affected system. Inspect the groove for burrs, corrosion, or damage before seating the new O-ring. Lubricate the O-ring with a compatible lubricant prior to installation to prevent tearing during assembly. Do not stretch the O-ring beyond the groove diameter or use tools that may nick or cut the sealing surface.
