I bought two different flaring tools in the last month and had problems with both. The first tool was the Ridgid 377
I already own one that is at least 8 years old. I bought this one for the installers. I tried to flare 5/8" tubing but the block would not hold the tube securely. Since we were an hour from the shop I didn't want to drive to get the older one. I finally had to wrap emery cloth around the tube in the block so it would not slide. Ridgid wanted me to send it in so they could check it, but rather I returned it to the supply house instead.
I then bought a YJ 60278. When it arrived I made a couple flares at the shop before giving it to the installers. They looked fine. Yesterday the installers were putting together a 3/8" coupling for a ductless lineset and the joint would not hold pressure. They were using Nylog on the flare and threads. They cut and flared the tubing 3 times without success. Then they got a new 3/8" coupling and new refrigeration flare nuts. Same problem. Monday we'll braze the joint.
I buy high quality tools to avoid problems such as these.
Has anyone else had problems with these tools?
