Answer This Question

Thank you for your interest in Danco products and for your inquiry. Kohler part number 78132 appears to be used on a toilet handle. Unfortunately, Danco model number 80990 will not work for your application. It is used to secure a faucet to the counter.

            Is the thread 1/2" NPT?
            ByMar 30, 2020
            1 Answer | 
            Answer This Question

            Thank you for contacting Danco. This locknut has a thread of 1/2 in. IPS. IPS is Iron Pipe Straight thread. It's meant to seal on a washer (like the threads the hose for your toilet or faucets it attaches to). NPT is a tapered thread, designed to seal on the threads, which is why you put pipe tape on them - to lubricate them and help the threads deform and create a seal.

                      These Work GOOD!
                      Used these on a well-made brass bathroom faucet that should've had brass shank lock washers. Well wouldn't you know it didn't and the old ones literally disintegrated. These are near universal and they fit well and snug up tight. The old ones lasted over 5 years. I suspect that these will last at least that long.
