Questions & Answers

Standard size of hose for toilet
ByAug 7, 2026

Answer This Question

Most areas use a 3/8" OD compression inlet toilet connector. A 3/8" OD compression X 7/8" ballcock nut would be considered the most common. That is our part number: B1-20DL F or Home Depot SKU#: 405663 Also available in 12" and 16" If you are having trouble finding the correct connector, contact technical support at 877-272-7755 Thanks

    The standard size for a toilet water supply hose is 3/8-inch compression connection (to the shut-off valve) and 7/8-inch ballcock connection (to the toilet tank). The length of the hose can vary.

      Answer This Question

      The 7/8" ballcock thread on the toilet will attach to our connector. The length will depend on your supply stop location and the 3/8" OD compression inlet is the most common connection, but you would need to verify that is the outlet size of your water stop. Thanks

                    I had to replace my current hose after my remodel. This matched the old one and looked pretty decent.

                    Reliable fitment and quality
                    Good quality toilet supply, have been using these for several years. The shorter length (12") allows for a clean installation without any loops or twists in the supply.

                      My old supply line was leaking so I replaced with this. Super easy fix and the leak is no longer there. Took a total of 5 minutes. Definitely suggest this for the supply line needs

                      Works great, is as of the do so we them they can’t believe they are not in the same room

                      They're easy to use and easy to make not leak. The braided exteriors resist kinking in tight spaces behind the toilet.

                      Great price and really well made. I'm very happy with it. I used it for a bidet in my guest bath. It was super easy to install and use, unlike the rigid pvc/plastic lines it replaced. I got a couple more for my other toilets. Recommended.

                      Definitely better than the existing plastic connection from the wall to the toilet. I should’ve went a little size shorter, but the size I purchased worked just by adding a loop in the hose.
