Have to politely disagree with bugman - used to be true.
Summit is buying so many parts from the Chinese importers like Wysco, Super Sunny, & Proform now that a lot of their house brand stuff is Chinese.
Can't assume that the stuff is private label Earl's or Russell anymore.
I've used some of the Chinese stuff without any problems, just have to be cautious. More chances for mfg. defects. The guys making the parts don't know what they are. If it doesn't look or feel right, don't use it(like everything else in life, right?)
BTW - The "Made in the USA" laws are total crap. As long as there is an operation performed on the parts in the USA (including repackaging) you can say it's made here. I bitch because I'm a USA MANUFACTURER.
My personal preferences for hose ends or fittings are XRP & Goodridge. Goodridge stuff is pricy but XRP stuff is reasonable. Check around for pricing. A bunch of the Roundy Pounders (circle track guys) use XRP stuff, and use way more of it than we ever will.
