Pentair O-RING Clamp 4000 Series Lid 071439

Buying part 071439

This Amazon listing identifies Pentair model 071439 as a filter lid O-ring for the Purex SMBW 4000 series. Match that exact part number rather than relying only on a generic clamp description.

Before ordering

• Check your old lid seal and note whether it is the O-ring itself or a separate clamp component.
• Confirm the filter family matches the listed Purex SMBW 4000 application.

Because the title and feature text use slightly different wording, compare the failed part to the seller’s description before installation. If your filter documentation lists a different component name, use the seller’s part number as the tie-breaker.
