Anyone know the dimensions of the o-ring found under the cast control knob on a BX-2 400? I'm guessing the same o-ring is used on the 500s and 600s as well.
i bought some o-rings at the local hardware store. i just pulled the tag and i hope this is the right one. it's a #35 o-ring from danco, part 96749. the dimensions are 11/16" OD x 9/16" ID x 1/16th". they are slightly oversized and make the pre-set knob very tight, but the next size down is way too loose.
Thanks Alan!
