Perfect fit for our 25-year-old Aquapure AP11T. Had a slow drip, was instantly fixed.

Works well so far. Was easy to change. Came well wrapped and on time

They were a little on the big side, I had to squish the o ring in to make it fit. But otherwise very long lasting o rings

Good quality, seamless O-ring. Perfect fit for AMF Cuno Accu-Pure Model AP11S dirt/rust filter. These last for years, so a decent price for 3.
