The threads are molded just big enough that they don’t screw on properly. Out of four of them only 1 fit right, 1 just barely fit, and 2 had threads so bad they wouldn’t work. Ended up having to buy some from Napa.

Listed as a 21-36 replacement. It is not. Bought a 21-36 to compare it to from another company and is not even close thread wise. Do not buy!
