Replacement O-Ring for 4.5 Water Filter Housings

The 5.5-inch O-ring is compatible with all Whole House Filter Housings and Bluonics Well Water Triple System, although the diameter is larger than the 4.5-inch canisters. These O-rings have smooth surfaces, excellent oil and heat resistance, wear-resistant, and provide good sealing performance.

The replacement O-ring is designed for Bluonics Whole House and Well Water Filter 4.5"x 10" and 4.5"x 20" models, as well as Triple Well Filter units. Before purchasing, it is crucial to confirm the required size and material to ensure a proper fit.

Crafted with heavy-duty premium materials, this seal ring is made of high-quality rubber, lightweight, soft, and flexible, with a long service life. It can be used with all food-grade lubricants to help maintain a leak-free water filter system.

Replacing the Bluonics O-ring can solve issues such as leaks and restore your filter system to peak performance and efficiency. The O-ring color is white, making it easily identifiable.

These small rubber O-rings are widely compatible, suitable for a variety of applications beyond water filtration, including automotive, pressure washers, bathroom floor drains, filters, pumps, water hoses, plumbing pipes, engines, valves, and air conditioning maintenance.

The smooth surfaces, oil and heat resistance, and wear-resistant properties of the O-rings ensure reliable sealing performance, while the clear O-ring seal provides a visual indicator of the proper placement. Customers are advised to carefully confirm the size and material requirements before purchasing to ensure a perfect fit and optimal performance.
