Description
Formed Stainless Steel D Cell Freeze Plug
These 304 stainless steel, 34.3mm freeze plugs (expansion plugs) have been formed to a ~50 degree cone to better guide solvent down into the trap while catching patches. Center marked. Weigh ~.6 oz each. ~3/8″ tall, ~1.350″ max diameter Ready for you to use in your D cell Solvent Trap. Expect D cell plugs to be tight in aluminum flash light tubes. Recommend reducing the OD if you have to use the cheap aluminum tube (and the plugs are tight). Better solution is to buy a tube made for these plugs.
Center marked by a spinning drill bit.
WE ALSO SELL UNFORMED FREEZE PLUGS!
Sold as gun cleaning equipment only. ALL NFA RULES APPLY. WE WILL NOT ACCEPT RETURNS OF ANY DRILLED/MODIFIED FREEZE PLUG. We will not ship these internationally (ie to Canada).

This product was designed to near perfection. The material was great, the dimensions are consistent. The price was right. Thanks Badger!

Awesome, exactly as described, very fast shipping, I definitely recommend Badger Ridge👍

Concentric and easy to true-up in the lathe. .060 thick to
take high solvent pressures.

Parts fit my parts application beautifully. Not to mention they were actually cheaper than buying these same sizes locally.

These only get a 3 because not one single formed freeze plug had the center mark, on center. Every one of them were off center. Would need to use a lathe to get the holes drilled perfectly centered, but after I drilled, I had to drill larger than I wanted to make clearences tolerable when using a concentric rod for alignment. Even at that, I still needed to use a Dremel with carbide bit to make even more clearences work. Had to get crafty because I don’t have a lathe. I made them work with a bit of finesse. So just beware as a buyer, none of these are center punched or center marked as they claim.

I’m sorry you aren’t satisfied. However I don’t believe you have reasonable expectations. We try to educate potential customers by posting lots of information about our products. We also suggest in the listing that you read the FAQ: https://badger-ridge.com/faq/ From the FAQ:
Getting centered holes: When you start with stamped parts, then run them through a die and use a spinning bit to mark the center, the tolerances all stack (plugs aren’t perfect, dies have clearances built in between the components and the spinning drill bit, etc). So nothing is exact. But I (and many many happy customers) found our plugs to be well within usable tolerances. Factor in that the nose of the die wears at the tip… so the bottom of the cone is imperfect and makes an optical illusion: they are probably more centered than you believe! With stainless typically you can turn them over and look at the pin prick of metal made by the tip of the bit and rotate the plug around it like its an axis… you’ll be surprised at how much “more” centered it appears. You can also do the same with the drill mark: use it as an axis, rotate the outer rim around and it will look really good but the cone will appear to wobble: the cone isn’t perfect, and the rim will wobble because it isn’t perfect either, and the rim is tapered, all of which compound to make an optical illusion. Again use the mark as the axis of rotation and look at everything when you rotate it.
But even if you don’t like what you see, and your application requires you to put a hole in and enlarge it, typically folks use long drill bits and jigs to put the last enlargement through all the plugs in the tube at the same time, and drill rod to check for a wide (over bore) straight path through that final enlargement: it makes up for all variations in the drilling process.
For those still on the not perfect centered path here: Like all things in manufacturing there are tolerances. How centered is centered? How do you measure it? What is good enough? The answer to this gets into GD&T theory, and what one uses as clearances in their end use (aka over bore), and their techniques when drilling and enlarging holes. You need a GD&T definition of what center tolerances are, an optical comparator/CMM machine to measure this properly….
Bottom line: The part is stamped, its rim has a few thou taper to it, and the OD tends to wobble a few thou before we even pressed it into a cone, and the drill bit has to clear the centering hole in the die… in the end we produce a good part that works well if the user does their part.

The product is what I need. The plug is a little flared as they described so I have to apply some machining for my purposes, but fitting works well with approved interventions. No qualms in their works or product provided
