28826 is a Flair-It EcoPoly PEX tee fitting from Elkhart Supply, designed to create a branch connection in compatible fresh-water plumbing systems. The specified configuration is 3/4" x 3/4" x 1/2", allowing two larger lines to connect to a smaller branch. Its black plastic construction is intended for compatible PEX tubing installations, including recreational vehicles and trailers. Verify the part number and all three connection sizes before ordering, as retailer listings show conflicting size information for this reference.
