Hello,
after the MTI hose we just made a new product. A high quality clamp for resin and vacuum lines. It is a very solid clamp that does not need much power to close the lines. You can also regulate the flow very easy and precise.
If you are interested you can buy it at the same distributors who sell the MTI hose, just look at www.dd-compound.com and choose your distributor.
Maybee they do not have them on their homepage, but if you ask you will get them.
We made these product because I always had problems with the cheap clamps and the welding tonth.
And the clamps are made in America by a small welding company, so each one is hand build and tested.
