Description
The Aladdin O-245 Union O-Ring is a multi-purpose sealing component that fits 2.5-inch union assemblies across a variety of pool and spa equipment. Serving as a drop-in match for Waterway Crystal Water filters and Pentair System 3 components, it delivers broad cross-brand utility from a single part. Molded from hardy, pool-grade material that withstands constant chemical contact and pressure cycling, the O-245 forms a secure, leak-proof bond that keeps your plumbing connections tight. Checking this O-ring periodically and replacing it when worn is one of the easiest steps you can take to keep your filtration system performing at full strength.
