I would like to know the tensile strength of my Hampton 1500lb bar that is approximately 8 to 10 years old. It is a black oxide bar with brass bushings and measures approximately 29mm. It doesn't appear that Hampton makes a black oxide bar anymore, but the newer chromed 1500lb Hampton bars have a Tensile strength of 165k(bushing bar) to 185k(needle bearing bar). The current bushing bar has a diameter of 32mm and the needle bearing bar has a diameter of 28mm.
Does anyone know anything about the tensile strength of he older Hampton bars?

Sounds like this bar. Does it have rubber end caps? Or, do you think this one is 32 mm?

Mine doesn't have rubber end caps. There is a metal end piece that you can twist. When you twist it neither the sleeve or bar twists. Thanks for that link, I must have overlooked that bar on the Hampton site. I used that model number and it turns out that bar is a 32mm bar. It is on the lower part of the page in the following link.

I believe my bar is actually 28.5mm and it weighs 44lbs rather than the 41lbs that the bar in that link weighs. I'm just hoping that my bar is at least 165k psi.

That is an odd endcap design.
Are you wanting to do some olympic lifts with the bar? You probably heard the rule of not dropping a bar from overhead that is under 150,000 psi.
The fact that it is 28.5 mm and 44 lbs should indicate a quality bar.

I'm actually selling it to a friend and I'd like to know exactly what I'm selling him. As of now, he doesn't plan on doing any overhead lifts. Mainly benching and deadlifting and possibly some power cleans. However, he could change his mind and I just wanted to let him know if it would be ok to do olympic lifts with it. He plans on purchasing a second bar, and the quality of this bar dictates how much money he will put in the other bar. It has been my main bar since I bought it and I've always thought it was a high quality bar. Nice bushings and feels really solid yet has some flex (not stiff like my 32mm power bar). Problem is, I purchased it as part of a 300lb set. I don't recall what I paid for the set, but the guy either charged me an extra $100 or $150 to include this bar rather than what normally comes in a set. I was under the impression that it retailed for about $200 to $250 10 years ago. I've never had any problems with it, but then I haven't dropped it from overhead. He is 58 years old and just really getting into lifting. It is unlikely that he will ever test the limits of this bar with the exception of Olympic lifting (which may or may not ever happen - even if it did, I can't see him cleaning and jerking more than 135lbs). Nevertheless, I'd like to know what I'm selling him. The only negative I see with this bar is the the rings. I think these might be the suicide rings that Tom Lincir discusses in one of his Ivanko bar articles.

At least they are U shaped cuts and not squared.

I don't think they would give him a problem. I've dropped 200+ lbs on the crash bars in my rack and never had an issue.
