🔧 Efficient GM Transmission Cooling Line Die and Adapter Set: MASTERCOOL (71099-TC Silver 3/8") Review

Arrived on time. Described as new, obviously used. The box is oiled, the bag with its contents is dirty, the tools are worn and used. Very disappointed

I bought this set as my newest Mastercool crimping tool set and it works just as well as the rest of the set! Just make sure you put a light coat of lube on the inside of the die to keep the pipe from sticking. Another great tool from Mastercool.

I haven't used these particular adapters but the others that were in the set I used work great. I just ordered them to complete the set. The reason for the 4 stars is the storage box, not the adapters. They do not fit in the space provided in the case.

Excellent quality tool! This set is included in my black Mastercool Universal Hydraulic Flaring Tool Set (71475-PRC). There is room for it in the case but not included, probably to keep the price down and because a lot of people will need it. I believe in having a complete kit in a case and not waiting for tools when you need to get the job done.

I've used this on stainless steel tubing and it works. Be sure to apply enough pressure or you will deform it and the barb OD will be greater than approximately 0.010 inch which may result in the end of the hose not fitting into the fitting. Practice on some pipe scraps before using it. It depends on the pipe. Compare the result with the original sample to see how much pressure provides the right shape. If you form an oversize, it can be neatly filed down a few thousandths if you need to use…
