Value Collection ZMSCS70229 Silicone O-ring Dash 229 10-pack

Product Description

The VALUE COLLECTION ZMSCS70229 is a round cross-section silicone O-ring designed for static and dynamic sealing applications across a broad temperature range. Sized at 2.375 inches inside diameter and 2.625 inches outside diameter with a 0.125-inch thickness, this is a standard Dash 229 O-ring. The silicone compound provides reliable performance from -80 degrees F to 450 degrees F, making it well-suited for systems that experience extreme thermal cycling or sustained dry heat. Each package contains 10 rings. Plumbers, HVAC technicians, and mechanical contractors install this type of seal in fluid and gas handling assemblies where consistent compression and weather resistance are required.

This O-ring is appropriate for residential and commercial applications where the sealed media includes oils, chemicals, or solvents at moderate concentrations. Its white silicone construction offers good ozone and weather resistance, which suits outdoor or exposed mechanical assemblies. It is rated hard at 70 Shore A hardness. Note that silicone has limited oil resistance compared to nitrile or Viton compounds, so verify media compatibility before installation in petroleum-heavy environments.

Installation Notes

Power down or depressurize the system fully before replacing any O-ring. Clean the gland seat of debris, old lubricant, and remnants of the previous ring before seating the new O-ring. Apply a compatible lubricant to the O-ring surface to ease installation and reduce the risk of tearing during assembly. Verify media and pressure compatibility against the silicone compound ratings before returning the system to service.
