Was a little bummed last night when the O-Ring on my small powder rotor started cracking and causing an occasional hangup resulting in an empty case. Of course it's a weekend and had planned to put out alot of reloads this weekend.

I figured someone here on THR might know if it's a standard o-ring that I might find local before I attempt scrounging the local hardware stores.
 
Not likely since it has a small cross section vs it's OD. You may try the plumbing section of a good hardware store and might find one close enough to work.

If you have the other size rotor(rile-pistol), swap it out till you get a replacement.

Call Hornady in the morning and they will send you a replacement free.

Why I did not even think about swapping the o-rings with the large rotor is just plain embarrassing:(. Thanks for the help!

Short term, it sounds like the problem is solved.

First, I doubt you would find the o-ring available at a local hardware store but you never know. You need the cross section of the elastomer and the inner diameter of the o-ring. You would not need any fancy elastomer.

But, it is probably a standard size. I doubt Hornady would design the measure to use an o-ring that is not available off the shelf. It is just not cost effect unless you need billions and billions of them or have a super special application. (It is amazing how many different size o-rings are available "off the shelf")

A local industrial supply house might have the right size but they are usually closed on the weekends.

Certainly, one of the o-ring suppliers would have them such as O-rings and More (https://www.oringsandmore.com) but you may have to buy a lifetime supply for just one.

Hornady is probably your best source. Get a couple so that you have one on hand incase there is a future failure.

P.S. my post #4, there are o-ring kits that come with long lengths of o-ring material and of several diameters, a cutting and glueing gauge, a tube of "super glue".

With the appropriate diameter elastomer, a new o-ring can be made on the spot. Also, larger diameter o-rings made with the desired diameter elastomer can be made smaller with the kits.

The kits are not terribly expensive, $30-$50 for a basic one, but again more than you would need for just one or two o-rings.
 
I will call Hornady tomorrow, they have been really good taking care of any issues. I actually keep quite a few spare parts in case of weekend issues. I will now pick up a half a dozen o-rings for the future.

The best fix I ever got from Hornady were shims for the power measure. The best and final fix for a nagging problem.

Yup the shims stop any movement what so ever. I tried larger o-ring but didn’t work very good.
 
Ace hardware story alway had a large supply of screws and stuff for guns, in case you have one where you live.
 
A tip for you all. Get some super glue and something for a cleaner. I always have a can of Carb Cleaner around and use that. Clean both sides of the joint and let dry. Then put a small bit of super glue on one side and glue back together. Keep your fingers back from the joint so no gluing fingers is involved.;) Should hold until replacement is procured .
 
An industrial gasket/o-ring supply house for hydraulic cylinder and control valve rebuilding is your best bet. I’ve had the same happen and went straight to one. I buy my LNL bushing gaskets there as well. Cheaper too. Some folks on this forum are replacing their shell plate springs with o-rings too.
