480-14 Generic 1/4 Inch Tee Fitting, 3 Way Water Line Splitter, Universal Water Filter and Fridge Water Line Part

Need to run two outlets off one water line? The 480-14 is a generic 1/4 inch tee fitting for 1/4 inch water tube, giving three connections so a single line can branch two ways. It is a handy part for under-sink filter setups, fridge and ice maker lines and other small water line jobs where one supply needs to feed two places.

Splitting a 1/4 inch water line

A tee lets one supply line feed two outlets at once. A common use is running filtered water to both a drinking water tap and a fridge dispenser, or teeing a fridge line off an existing filter system. It can also bring a bypass or flushing line into a setup. The water pressure is shared between the branches, so when both outlets run together each one may flow a little slower. Before buying, measure the outside diameter of your tube to confirm it really is 1/4 inch, as some metric tube looks almost the same.

Part details

• Generic part number 480-14
• Tee shape with three 1/4 inch connections
• Splits or joins 1/4 inch water lines
• Suits fridge, ice maker and water filter tubing

Fitting the tee

Shut the water off at the tap or isolation valve and open an outlet to release the pressure. Cut the tube square with a sharp tube cutter or blade, never with side cutters that squash it. Connect each tube fully into the tee following the fitting's design, then turn the water back on slowly and check every joint for weeping before closing up the cupboard.

Questions about this part

Is 1/4 inch tube the same as 6mm?

Not quite. 1/4 inch tube is about 6.35mm across, while 6mm tube is metric. They look alike but don't always seal in the same fittings, so check the size printed along your existing tube before connecting it.
