3 o-rings for standard sized RO and RO/DI filter housings to replace cracked or torn o-rings that would allow water to leak
A 1 gram tube of silicone for lubricating the o-rings to ensure that they seal completely and don't rip or tear when tightening
It is recommended to change the o-rings once a year with each filter change to ensure that your housings are completely sealing to prevent costly and messy water leaks.
Perfect fit, super-fast service, and excellent customer servicel
The O rings seldom need replacement because they always look in good condition, so I just put the same ones back after wiping clean. I appreciate the silicon, though, and have saved the new rings.
In order to insure that your pre-filter housings fit snugly, it's a good idea to replace them occasionally in order to prevent leakage when replacing filters. The silicone will help to protect the rings. They're not expensive, and spare parts are worth having on hand.
Two attempts and still not the right o rings. Finally found correct ones else where. Why at least three sizes?
AWF support is responsive. Their packages include everything needed. An example is including the 1g of silicone for lubrication. O-Rings appear to be of the highest quality. Responsive, attention to detail. Great company.
