Product details
The Hayward ECX12866 is the gauge adapter for Perflex extended cycle DE filters. It is the genuine Hayward part, molded in plastic.
What it does
The adapter threads into the filter head and does two jobs. It gives the pressure gauge somewhere to mount, and it doubles as the inspection port. Because it is the one fitting on the filter that gets unscrewed and re-tightened routinely, it is also the one that takes the most abuse.
Which filters it covers
Hayward lists the adapter for the Perflex EC50, EC50C, EC50A and EC50AC filters, and for the EC65, EC65A, EC75 and EC75A. If you are not sure which one you have, the model is on the label on the tank.
Fitting it
The o-ring that seals the adapter is a separate Hayward part. A new adapter on an old, flattened seal will still weep, so plan on changing both while the filter is open.
