490-14 Generic 7/16 Inch Female x 1/4 Inch Adaptor Fitting, Universal Water Filter and Fridge Water Line Part

Joining a 7/16 inch connection to 1/4 inch plumbing comes up a lot when fitting under-sink filters and fridge water lines. The 490-14 is a generic adaptor fitting with a 7/16 inch female end on one side and a 1/4 inch connection on the other. It is a universal part rather than one made for a particular appliance brand, so fit comes down to matching the sizes and connection styles on your existing system.

Using a 7/16 to 1/4 inch water line adaptor

Small water lines for filters, ice makers and drink dispensers use a mix of thread and tube sizes, and the parts don't always line up. An adaptor like this bridges the gap between a 7/16 inch male thread on a filter head, valve or housing and the 1/4 inch line or fitting that runs on from it. Replacing a cracked or stripped adaptor is often all it takes to stop a slow drip at a joint. A fitting that has been overtightened, cross threaded or left under strain from a stretched line is a common source of leaks and weeping connections.

Checking the sizes before you fit it

Turn off the water supply and relieve the pressure by opening a dispenser or tap before undoing any joint. Measure or compare the old fitting so you know both ends match, including whether the 1/4 inch side is a tube or thread connection. Start the female thread by hand to avoid cross threading, snug it up without forcing it, then restore the water slowly and watch the joint for weeping.

Questions about this part

Does this fit a particular fridge brand?

No, it is a generic size-based fitting rather than a brand-specific part. It suits any setup where you need a 7/16 inch female connection joined to a 1/4 inch line or fitting. Compare it with your old adaptor before ordering.
