Screw Compressor Clamp

Used to regulate flow through a flexible tube. The screw driven jaw can be accurately adjusted in any position from closed to fully open to allow you to get just the rate of flow you want. The swing-away bottom jaw design lets you install over already connected tubing. The jaw opens to a maximum of 7/8" high and is 15/16" wide. Made of nickel plated steel, all edges are rounded to avoid cutting the tubing.

Rubber Stopper

Pat's been hanging around the medical supply house again. We now have a boatload of rubber stoppers, the kind you see on bottles of liquid medicine, crimped down with an aluminum collar. (Pat didn’t buy the aluminum collars.) The medicine is removed via a hypodermic needle through the stopper. The rubber stoppers come in blue, gray or orange. All three stoppers fit (13 mm) dia opening. The blue and gray are 3/4” across the top, 5/16” top to bottom. The orange are 9/16" across the top and 9/16" top to bottom. Why would you want them? Because they'll fit many of the small wide-mouth and slope-shouldered bottles in our Bottlemania listing. Pat's really good!

Hard Dentistry

Prick tiny bits of gunk from nasty places with these U.S. made hardened stainless steel dental tools. But please don't use them for dental work. They are slight seconds, and some may have been re-worked which only matters to teeth. Trim excess glue from models, place a barrel on the deck of the ship-in-a-bottle, clean a rasp. If you need the strength and durability in a tiny pick, you need these tools. We have an assortment of the sort you've seen laid out on your dentist's tray. We'll pick (3) different ones for you.
