Product details

The Pentair 86006900 is the bulkhead o-ring used in both the upper and the lower bulkhead positions. It is the genuine Pentair part.

Where it goes

It appears in the parts listings for the Pentair Clean and Clear Plus cartridge filter and for the American Products Titan RPM DE and Quantum RPM cartridge filters. The bulkhead is the port fitting through the tank wall, and this o-ring is what keeps water on the inside of it.

When to change it

O-rings harden, flatten and take a set. Once one has, it will pass a slow weep no matter how carefully the fitting is tightened, and overtightening to chase the leak only cracks the plastic around it. Change the o-ring any time the bulkhead is disturbed, and lubricate the new one with a silicone based o-ring grease rather than anything petroleum based.

Questions and answers

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

Is this the upper or the lower o-ring?
Both. Pentair 86006900 is used in the upper and the lower bulkhead positions.
Which filters is it listed for?
It appears in the parts listings for the Pentair Clean and Clear Plus cartridge filter and the American Products Titan RPM DE and Quantum RPM cartridge filters.
How many come in the listing?
The facts do not state a quantity. If you are replacing both the upper and the lower position, check the count before ordering.
Should I lubricate it?
A silicone based o-ring lubricant helps a new o-ring seat and makes the next teardown easier. Avoid petroleum products, which attack the rubber.
