Measure the outside diameter (OD) of your tube. 1/4" is the most common size for under-sink filters, fridge lines and RO systems.

Full product details

Read the full description

DMfit's straight union joins two lengths of water filter tubing in a straight line, for extending a run or repairing a damaged section. Choose AUC0404W for ¼" tube or AUC0606W for ⅜", or a reducer: AUC0504W (5/16" to ¼") or AUC0604W (⅜" to ¼").

DMfit makes its push-in fittings from acetal copolymer (POM) and lists FDA, WRAS and ANSI/NSF-51 and 61 approvals. Tube pushes in to connect and releases by holding back the collet, and fittings and tube can be reused.
