Harbor freight orings

[The Hobbit]

In need of some orings, primarily for macro fittings. I had read somewhere about people having decent luck with HF orings, so since I loathe buying things like this online, figured I’d pick a pack up. Now my questions which material should I grab(Viton, nitrile, HNBR?).

thanks

I've had bad experiences with chinesium o rings. In my case they had a seam running around the exterior, you know, that surface that's the most critical for sealing.

I had bad luck with them even being the actual size. They always seemed to be slightly smaller/thinner than actual spec. In many cases they worked fine and other cases they didn’t.

I've used the orings that came in a clear container with partitions and had the same experience as Trbo. The oring cross section was also oblong instead of round.

I bought another kit that came in a coloured box where small orings sit on pins on the lid and nestle into the centres of the big orings on the bottom and those orings were good. I bought this kit from a hydraulic store but HF/PA sell a kit in the same box so those orings might be good. Just be aware if you only plan to use this for paintball that you'll get a bunch of orings that you'll never use.

Nitrile is a good all round material because it's cheap and solvent resistant. I personally wouldn't bother with the other materials unless they're called for specifically.

That's funny because mine came in the same box but were absolute garbage.

I order everything through theoringstore.com these days. Great guys with a paintball background who really know their stuff. Their rings are great quality, I've never had a problem with anything QC related. They even helped me track down some rings that were a weird European spec

I also can say cheap oring kits can be more hassle than they’re worth. Check a local hydraulic or hose shop for a decent kit, or from theoringstore.com. Prices are good, get what you need instead of buying waste, helpful and they toss in some salt water taffy. I don’t know any brick and mortar stores that sell orings individually based off size.

I didn't get any taffy with my last order

Inflation is why we can’t have nice things. Times are tough if they quit supplying taffy. It’s been a year since I’ve ordered from them
