Review: High quality, single o-ring design - Used on 3 builds - High quality build, durable design, good compression on rough ended tubes. Easy on the fingers. "You've purchased this item 3 times"
Review: This was my 2nd & 3rd set of these - I prefer using these over the original compression fittings for Thermaltake's PETG lines. They're easier to use. They allow for a slight variance in tube fitting to butt; meaning it doesn't have to be perfectly aligned to get a 100% no-leak seal on the line. This is due to these fittings have 3 o-rings over the 1 (I think it's one on the old ones) and 1 additional o-ring for the connector outer too that screws down into the rest of this. These are 3 piece compression fittings. You have a base (what I'm calling the butt) that screws into the socket (standard 1/4" fitting), then a 'fitted' center ring that has the 3-o-rings in it that fits over the end of the line, and then the screw on fitting that has an additional o-ring for the 'top' of the ring with the other o-rings inside it. So a 4 o-ring system not including the other standard seals too. The tool could use some reworking. Sometimes it works flawlessly, sometimes it's a struggle because it WILL slip out of the notching. Maybe Thermaltake can take a NOTE here and add some rubberized 'feet' that are on those notches to make it maybe not SLIP OUT of the notching when you're tightening the base down. Overall I'd buy more again. Sometimes I get them to replace where I've had to use pliers to take the fittings off after a year of pressure and other factors that won't let them loosen back up so they get a little stripped of color. Or, sometimes I need more because different loop idea requiring more turns, joints, etc. Recommended if you don't want to use the old ones or if you want a nearly 100% guarantee that these seals won't leak. Mine NEVER have unless it was user error and there was this one time I flooded my GPU...thankfully it did not damage that...whew. Pics attached of how the fittings look in a loop. Cheers!

### ⭐⭐⭐⭐⭐ Straight pipes in fittings and no leaks (to some who say they leak)
*by R***E on June 19, 2019*

Worked great and great quality! To people talking about these leaking, make sure everything is completely straight in the fitting while leak testing. It's not the fittings. It's more about your pipes being straight. I did a leak test(everything is unpowered but the pump), one fitting had a little leak. Turned it off, had paper towels out, so no issue. Noticed the pipe wasn't completely straight. Adjusted it a little bit and then not a drop out of it. So just make sure everything is straight and you'll be good to go.
