            Isn't this essentially an extension line? I'm installing a tub filler, but the 32-in supply lines are a bit short for what I'm needing, and it seems like this would work as an extension.

            Yes this works perfectly as a supply line extension. I got a bunch of them so short supply lines won’t be an issue for me anymore. It’s 3/8 male on one end and 3/8 female on the other. No leaks and a fast solution to a common problem!

                An extension is exactly what I need, too. By all appearances this should work. I don't understand why the manufacturer says they need "more information".

                    Can this be used as a simple 3/8 in extension. The hot and cold water pipes on the new sink I am installing are about 4 inches too short.

                          You just remove the compression nut on the one end and 3/8 male is underneath. So you now have a supply line extension, 3/8 male on one end, and 3/8 female on the other.

                              “Just remove the compression nut on one end”. Yes, but how do you remove it?

                                This faucet supply line arrived exactly when I needed it. The construction is solid, with cleanly machined threaded fittings and well-finished braided hose. Like some reviewers, I would have preferred a shorter hose, but the 20-inch was what was available on install day. I simply zip-tied the extra length neatly, and within minutes had a leak-free, fully operational faucet. These supply lines don’t last forever and are typically replaced during faucet repairs or upgrades, so reliability matters. This one checked all the boxes. Works .

                                This BrassCraft supply line worked exactly as expected for my plumbing project. The braided polymer feels very durable and flexible enough to route easily under the sink. The compression fittings threaded on smoothly with no leaks at all. Great quality and a very straightforward installation!

                                  Used to extend from the angle stops to the faucet supply lines in a laundry sink. Worked and didn’t leak. Could have used half this length but was not available in store any shorter.

                                  This item works perfectly as a supply line extension. I bought a bunch of them for all those times when you just need a few inches more length. No leaks! A fast and easy solution to a common problem. You just remove the compression nut and you have 3/8 male on one end, and 3/8 female on the other. These are a real time saver!

                                    Using no tools at all, these hoses were used as extensions to my faucet connections. No leaking on first try! I only needed about 4 inches but the 12 inch was the shortest available. Twisted them around to use up the length and there was no kinking at all.
