Having a hell of a time finding 4 stainless steel fender washers in 5/8 size... Any recommendations? Seems like this is a common issue.. Just trying to get an idea.
I hear ya. I bought 1/2" SS fender washers at Home Depot and had a guy at my company's machine shop bore them for 5/8. You should be able to find them online at Fastenal. Hope that helps.
Lowes has them, hard to find sometimes...but, when I priced it out it was cheaper to just buy the whole setup from http://www.bargainfittings.com/ along with some silicon tubing...
