Important Note 1: Does your filter housing use a square/flat gasket rather than a round o-ring?
Some of the older 3M AP801 models use a flat (squared-off) gasket rather than the round o-ring. These housings use the 68898-31 gasket rather than the newer 68898-32 o-ring. If you need the flat 68898-31 gasket, you can click here.
Important Note 2: Do you have one of the newer 3M AP801B, AP801T, AP802B, AP802T housings?
The newer 3M Aqua Pure AP801B/T and AP802B/T housings use the newer 3M 70-0203-5277-2 o-ring. It is slightly smaller in diameter than the older 3M 68898-32 o-ring. If you have one of the newer 3M AP801B, AP801T, AP802B, or AP802T filter housings, you can click here find your o-ring gasket.
