Quick overview
- Measured size 3/16 inch cross section by 2 5/8 inch, so it can be checked against the one coming out.
- White O-ring Supplied in white.
- Triton commercial filters Listed as a Pentair Triton commercial side mount sand filter part for the TR100C and TR140C.
- Genuine Pentair Factory part 274495 rather than a hardware store O-ring in a similar size.
- Seals matter An O-ring that has flattened or hardened is a slow leak waiting to show up on the pad.
- Cheap insurance Worth having on hand before opening a filter, since a used seal rarely goes back as well as it came out.

Product details
Pentair 274495 is a white O-ring measuring 3/16 inch by 2 5/8 inch. It is the genuine Pentair part, listed as a Triton commercial side mount sand filter part for the TR100C and TR140C.
Check the size
O-rings look alike and do not behave alike. The 3/16 inch cross section and the 2 5/8 inch dimension are what to measure against the seal being removed, since a near match will either roll out of its groove or refuse to seat.
Fitting
Clean the groove before the new O-ring goes in and check that the mating face is free of grit. An old seal that has flattened or gone hard is the usual cause of a slow weep after a filter has been opened and closed, and replacing it while everything is apart avoids a second trip to the pad.
