Product details

The Pentair 154001 is the 3 in. adapter flange, the genuine factory replacement listed under the Triton C-3 side mount sand filter parts.

What it does

The adapter flange is the piece that carries the transition between the filter port and the plumbing bolted to it. It takes the mechanical load of the connection and it has to stay flat and true for the o-ring behind it to seal.

Why it is replaced

Flanges crack, warp with heat, or get pulled out of shape by someone chasing a leak with a wrench. Once the sealing face is no longer flat, the joint weeps and tightening it further only makes the distortion worse. The o-rings that go with it, the flange adapter o-ring and the pair of spacer o-rings, are separate parts and worth replacing at the same time.

Which filter does this flange fit?
It is listed under the Pentair Triton C-3 side mount sand filter parts.
What size is it?
3 in.
Do the o-rings come with it?
No. The flange adapter o-ring and the spacer o-rings are separate parts, and the spacer o-ring is used in pairs.
Why would the flange need replacing?
A flange that has cracked, warped from heat or been over tightened will not seal against its o-ring, and the joint weeps no matter how hard it is drawn up.
