March 0155-0215-1000 Teflon Encapsulated Viton O-Ring

Product Overview

The March 0155-0215-1000 is a Teflon-encapsulated Viton O-ring offered as an alternative housing seal for compatible March SP-TE-7 self-priming magnetic drive pumps. It provides the designated sealing interface between adjoining liquid-containing components.

The encapsulated construction combines a fluoropolymer exterior with an elastomeric core. This part is a specific sealing option and should not be confused with standard Viton or EPDM alternatives.

Key Features and Benefits

• Teflon-Encapsulated Viton: Matches the manufacturer-designated optional seal construction.
• Housing Sealing: Supports the intended wet-end sealing arrangement.
• SP-TE-7 Application: Identified for compatible self-priming pump configurations.
• Individual Service Part: Allows replacement during housing maintenance.

Applications and Maintenance

This O-ring supports maintenance of compatible chemical circulation and transfer systems. A sealing component may require replacement after damage, flattening, incorrect installation or loss of sealing performance.

Clean the mating surfaces and inspect the sealing groove before assembly. Avoid twisting or pinching the encapsulated O-ring during installation. Confirm chemical compatibility for the complete pump and process liquid.

Compatibility and Selection Guidance

Listed as an option for compatible SP-TE-7K-MD and SP-TE-7P-MD configurations. Verify the exact sealing location and original part number before purchase; other O-rings in the same pump assembly have different dimensions and SKUs.
