304 Stainless Steel Tubing, Length 12 Inch (30 cm), Tube Out Diameter OD 12 mm (15/32"), Pack of 2

Used it his SS tubing over a 5/16” bolt for an aesthetic look. Easy to cut with a hacksaw. Each piece individually wrapped to prevent nicks during handling and shipping. Clean interior of tube - new cleanup needed to insert a bolt or rod.

I'm using these in a 2,500 psi hydraulic system with 12mm steel compression fittings. The diametrical tolerance of these tubes seems to be pretty random, and it can be a little challenging getting into the fittings, but so far-so good. I gave five stars because this is the only place I could find 12mm tubing, otherwise three stars for quality control.

Quality and finish is great, however, the description claims 3/8 ID..nope, had to mill it.

I need one as a lever for my Allen wrench to undo recalcitrant screws and it's sturdy enough to handle the job.

If you need more precise round tubing with uniform wall thickness, look elsewhere. Checking on my calipers the outer diameter ranged from 19.95mm to 12.25mm. The packaging is fine, so it's as if was squashed on transit, but it's definitely not perfectly round, more like oval

Great value for the price.

tube worked great, use on hydraulic cylinder.

I agree with other reviews, this pipe is not precise. It seems to be for decoration, not precision. If you think you'll be able to put it into a 12mm bore, you cant. It's not perfectly round and it's not 12mm.
