About This Item

OEM Seal Plate Bolt for Pentair WhisperFlo and IntelliFlo Pumps

The Pentair 070431Z is the OEM replacement stainless steel hex cap bolt for the seal plate on Pentair WhisperFlo and IntelliFlo pump models. Two bolts are required per pump for a complete seal plate service.

⚠️ IMPORTANT: QUANTITY REQUIRED
Two (2) bolts are required per pump for a full seal plate service. This listing is for a single bolt — order the quantity you need before beginning work.

The seal plate bolt secures the seal plate to the pump housing, maintaining the compression and alignment necessary for the mechanical shaft seal to function correctly. A loose or corroded bolt can compromise seal plate integrity, leading to leaks at the pump volute. Replacing these bolts at each seal service interval is standard practice.

Specifications

Pentair Part Number 070431Z
Description Hex Cap Bolt, Seal Plate
Thread Size 3/8-16
Length 2"
Material 18-8 Stainless Steel
Head Type Hex Cap
Quantity Included 1 bolt (2 required per pump)

Pro Tip

When servicing the seal plate on a WhisperFlo or IntelliFlo pump, replace both seal plate bolts at the same time — corrosion and fatigue affect both equally. Inspect threads on the pump housing before reinstalling; cross-threaded or damaged housing threads will cause ongoing leak issues regardless of bolt condition. Match the 3/8-16 x 2" specification and 18-8 stainless grade stamped or listed on your original hardware before ordering.
