Product details

This is the Waterway 519-7431 pressure gauge adapter, the fitting that carries the pressure gauge on Clearwater II cartridge and DE filters.

Why it matters

Filter pressure is the number that tells you when the cartridge needs cleaning or the DE grids need service. That reading only means something if the gauge is mounted square and the joint is dry. A cracked or cross threaded adapter weeps, drops the reading and leads to a filter that is left dirty far too long.

Fitting it

The gauge is a separate part, so order it as well if the old one is fogged, stuck or reading high at rest. Use a thread sealant suited to plastic and tighten by hand, since a plastic gauge fitting splits easily under a wrench.

Questions and answers

What people ask about this product, answered by our pool techs.

Does a pressure gauge come with it?
No. This is the adapter alone. The gauge is bought separately.
Which filters use this adapter?
It is listed in the Waterway Clearwater II cartridge filter and Clearwater II DE filter parts.
Why replace an adapter that looks fine?
Threads pull and hairline cracks open up when a gauge is overtightened. If the joint weeps, or the gauge sits crooked and reads low, the adapter is usually the reason.
Do I need thread sealant?
Use a sealant suited to plastic threads and tighten by hand plus a small turn. Overtightening a plastic gauge fitting is the fastest way to split it.
