Product details

The Sta-Rite WC19-64 is the top clamp for filter models T-50TX, T-70TX, T-100TX, T-50TXR, T-70TXR and T-100TXR.

What the clamp does

The filter tank is built in two halves that meet at a seam sealed by an o-ring. The clamp is the band that pulls them together and holds that seal against system pressure. It is a structural part, so a clamp that has cracked, stretched or corroded through is not something to keep tightening.

Chasing a seam leak

When water weeps from the seam, most people replace the tank o-ring, which is right most of the time. If the leak comes straight back, look at the clamp itself. A band that has lost its shape, a bolt that has rusted and will no longer draw evenly, or a lug that has started to split will all leave one section of the seam under less pressure than the rest, and the o-ring cannot make that up.

Fitting

Always release system pressure and open the air relief before touching the clamp on a running filter. Draw the new clamp down evenly, and check that the tank halves are seated squarely before applying full torque.

Questions and answers

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

Which filters does this clamp fit?
Sta-Rite models T-50TX, T-70TX, T-100TX, T-50TXR, T-70TXR and T-100TXR.
My filter leaks at the seam. Is the clamp or the o-ring at fault?
Check both. A flattened or nicked tank o-ring is the usual cause, but a clamp that has stretched, cracked or seized at the bolt will not pull the halves together evenly and the leak returns with a new o-ring.
Does the tank o-ring come with the clamp?
No. The clamp is sold on its own, and the tank o-ring is a separate part.
Is it safe to reuse a rusty clamp?
Not if the corrosion has eaten into the band or the bolt. The clamp is holding a pressurized tank together, so a weakened one should be replaced rather than retightened.
