Product Review

Don't be fooled by o-rings made of inferior compounds, this Pool Ruler o-ring is made from OEM spec Viton (FKM) which is chlorine resistant and will last up to 4 times as long as generic o-rings. We back our product with a full season guarntee. If your o-ring fails, swells, or has a problem, contact us and we will refund or replace (your choice) for a full year.
