Expert Insight on Pentair Parts

The O-ring in your vacuum head compresses each time you attach or remove the assembly, and over time it begins to flatten or crack. Furthermore, replacing it before it fully fails prevents suction loss and reduces strain on your pump. Specifically, the latch often wears at the same rate, which makes this combined kit a practical upgrade during routine maintenance.

How do I know if I need to replace the O-ring or latch on my Pentair #186 vacuum head?

You should replace these components when you notice suction loss, water bypassing the seal, or a loose housing connection during use. Moreover, visible cracks, flattening, or stiffness in the O-ring indicate it can no longer maintain a watertight seal. Furthermore, if the latch no longer secures firmly or shows stress marks, this kit restores proper function and prevents premature wear on other parts.

Pro Tip: Replace O-rings annually in high-use pools or harsh climates to maintain consistent vacuum performance.
