Copper Tubing Pinch Off Tool CT-204

I pinched off a 3/8 line and put 500 psi on it. It didn't leak one bit. Is better than I expected.

The handle is not strong enough to apply adequate force. I'm going to weld a nut on the end and use a wrench

I don’t leave reviews. Normally but I’ve always liked this style pinch form factories. So I decided to buy it. Today I gave it a shot. Tightened there was still refrigerant passing thru. I had to seriously torque it. As I’m sealing the end of the port was spitting the refrigerant out thru needle size hole. Had to use my old reliable pinch of clamp. So low side ok high side not. I wouldn let recommend it but maybe you are luckier than me. Pretty and clean pinch but that’s about it doesn’t seal the high side

works very well

It does make a nice crimp but no matter how hard I cranked it I could not get a completely gas-tight seal. That wasn't a big deal for my application but if you are trying to service a small refrigeration compressor it might be.

I haven't tried it on a pressurized line but it should do well.

they was at a good price

This is a great idea but a horrible execution!!!! It looks like my kid made it! The metal ball part is ok. But then they used the cheapest metal on the planet for the twister handle! If you buy this you MUST also buy vice grip pliers to get it to seal
