Housing Seal Function

The O-ring provides an elastomeric sealing interface between the applicable housing components. Correct sizing and installation help maintain the intended fluid containment arrangement.

FKM Material

FKM is used in many industrial sealing applications, but chemical compatibility must be verified for the exact liquid, concentration, temperature and operating conditions.

Series 320 Compatibility

Distributor parts documentation identifies 0320-0006-1000 as a Series 320 metric O-ring. A related EPDM O-ring is listed under a different part number and should not be substituted without checking fluid compatibility and the original pump configuration.

Maintenance and Replacement

Replace the O-ring if it shows flattening, cracking, swelling, cuts or loss of elasticity. Inspect the housing groove and mating surfaces before installation, and avoid twisting or pinching the new seal.

Selection Guidance

Confirm the original elastomer and metric dimensions before ordering. 0320-0006-1000 is the FKM version for compatible March Series 320 applications.
