Review: Fitsapic type A housing - These Rings fit Apex type A housing but $5 for the little squeeze of Grease is a joke you can buy the O-rings themselves for $7 but definitely use Grease
Review: Great Buy Always change O Rings W/Filters - This worked out fabulous! My son replaced the filters. He was glad I ordered the APEC O Rings for the filters. I went to Home Depot and Lowe's who both told me they had Apec Filters and O Rings. After driving 30 minutes to pick them up they tried selling me a GE set. I refused to get those and came home and was glad desertcart had them.This worked out fabulous! My son replaced the filters. He was glad I ordered the APEC O Rings for the filters.

### ⭐⭐⭐⭐⭐ It is larger, but solves the leaking problem
*by A***R on January 5, 2024*

It's hard to sit the ring in the socket - this is obviously larger than the original ones. But once installed it fixed the leak.
