So, you bought a cool old clawfoot tub with an exposed Standing Waste drain on it, and you went to hook it up to modern plumbing only to find that the threads on the outlet of the drain aren’t standard. This used to be a major headache. Not anymore! This slip joint nut has an internal thread that 14 threads per inch, not the Standard 11 1/2 threads of today. This nut is commonly found on drains made by Mott and Standard. Supplied with washer, sold by the each. Nut is 2″ across the outside, thread on drain NEEDS to be 1 13/16″ OD
Have a Standing Waste drain with a different thread pitch (but not 14 TPI) on the outlet? Shoot us an e-mail! We can help!
