March 0157-0011-1000 O-Ring

The March 0157-0011-1000 Viton O-Ring is an OEM replacement wet-end sealing component designed for compatible March Series 8 magnetic drive pump assemblies.

This O-Ring features a 0.157-inch cross section and a 7.244-inch inside diameter. It installs between mating wet-end components to help maintain proper fluid containment and a secure seal during pump operation.

Constructed from Viton, the 0157-0011-1000 provides strong resistance to many compatible chemicals, oils, and elevated temperatures, making it well suited for demanding chemical circulation and industrial process applications.

March Pump uses this exact O-Ring in several Series 8 configurations, including TE-8C-MD, TE-8K-MD, and TE-8S-MD pumps. It is positioned between the pump housing and adjoining wet-end assembly as part of the pump's primary sealing system.

The 0157-0011-1000 is suitable for preventive maintenance, wet-end rebuilding, or replacement of a worn, hardened, flattened, or damaged O-Ring. Using the correct OEM seal helps reduce leakage risk and supports dependable pump operation.

Always verify your exact March pump model, fluid compatibility, operating temperature, and required seal material before installation.
