NOT compatible with other DB-series models (DB10, DB20, DB10P) or PurePlus blue housings. Please verify your model before purchasing. Includes 2 Different O-Rings – Thick & Thin for Proper Installation – The DB10C and PP-WFM10B canisters require two different seals: the thicker O-ring fits into the groove around the outer circumference of the canister (just above the threads), and the thinner O-ring seats in the groove at the top of the canister sump. This kit includes both sizes so you're covered in one purchase. Food-Grade Silicone – Safe for Drinking Water Systems – Made from BPA-free, food-grade silicone that meets NSF/ANSI standards for water contact. Resists cracking, hardening, and deformation under constant water pressure and temperature fluctuations — far more durable than standard rubber O-rings that dry out and leak over time.

Eliminates common leakage issues caused by worn, flattened, or degraded factory O-rings. Tool-Free, Drop-In Replacement – Quick 5-Minute Install – Simply remove the old O-rings, press the new silicone seals into the correct grooves (thick ring on the outer circumference, thin ring on the sump top), and reassemble. No tools, lubricants, or special skills needed. Ideal for routine filter maintenance without professional help or system downtime.
