Description

Product Overview

The Captain O‑Ring OR‑250 Filter O‑Ring 3‑Pack is engineered to deliver a dependable seal for a wide range of under‑sink water filtration systems. Each O‑Ring is molded from NSF‑61 certified buna‑N rubber, a material recognized for its resistance to chemicals, durability, and safety for potable water applications. The dimensions of each ring are approximately 5‑1/2 inches inside diameter by 5‑7/8 inches outside diameter, providing a precise fit for filter housings that require a robust, leak‑free seal. Manufactured in the United States by Captain O‑Ring LLC, the product adheres to strict quality standards and includes a warranty that underscores confidence in its performance. The three‑pack configuration ensures that users have spare seals on hand for future maintenance, reducing downtime and the need for additional purchases. With a price point of $14.29, the set offers an economical solution without compromising on material quality or fitment accuracy.

Usage

These O‑Rings are designed for straightforward installation in a variety of water filtration housings, including but not limited to Culligan WH‑HD200‑C, 3M Filtrete 3WH‑HD‑S01, 3M Aqua Pure AP801B/T and AP802B/T, DuPont WFAO100, and Hydronix HF45 models. Homeowners and professional installers alike can replace a leaking seal by first turning off the water supply, relieving pressure, and removing the filter housing. After cleaning the housing interior, the new O‑Ring is placed into the groove, ensuring that it sits evenly without twists or folds. The filter can then be reassembled, and the water supply restored, typically resulting in an immediate cessation of leaks. This product is especially valuable for households that rely on filtered water for drinking, cooking, and bathing, as it helps maintain the integrity of the filtration system and prevents contamination from external sources. The O‑Rings also perform well in commercial settings where continuous filtration is required, such as small offices, cafés, and health‑care facilities.
