Swiftech® introduces new Lok-Seal™ brand of compression fittings - Page 2

post #11 of 94
These seem good in theory

but they are ugly looking and that nut at the bottom is disgusting


I've used BP for years and never had problems with them leaking


If you want security I think the monsoons are nicer looking

I like the idea of allowing for a wrench to be used without tearing up the finish, and the design allows to control what unscrews, fitting or fitting from block. I have used same bitspower compressions for years, and I always use a wrench with teeth to tighten mine, similar to tightness Swiftech described with theirs, no way would I run mine hand tightened regardless of what others do. But the finish on my BP chrome has taken a beating from wrench teeth after multiple rebuilds, at distance they look ok, up close not so much. Also when removing BP, I have little control over what gets unscrewed, fitting or fitting from block, irritating at times.

I like the looks of the Swiftech and definitely the design improvements.

Pge 4 of 9, paragraph 2 relates a similar experience.

Ok. will work on it.

That article is no joke when spelling out risks of leaks from fittings, what a grim reminder that every joint of the dozen I have has the potential for catastrophic failure at any moment.
I'm ordering more fittings soon, I want to hear more about these LOK-SEAL ASAP!

There really is nothing special in their engineering, these are just fittings, nothing too complicated. But they are designed in accordance with conventional mechanical engineering standards, to the exception I must say of the short (5mm) G1/4 thread length which remains an unfortunate necessity dictated by our space constrained application. So user education is important, reason why I added specific fastening instructions to each of the product pages, something that few -if any, of the other vendors do for whatever reason. Read them, and apply them to your own setup by any possible means; you can never be too safe!

Looks: individual tastes cannot be argued with

BP's: this comment says "experienced user". Meaning that you most likely install your fittings using protected pliers like I used to; read page 3 of 9 here , and let me know if you agree or disagree. In any case, my primary point is that the sheer number of people reporting issues required an improvement in the way we do things, at least in my book.

Moonsoon: They do look quite fancy don't them? but see Twit's post here

It appears that you tend to favor form over function, and this is certainly a choice one can make. BP fittings look cosmetically superb IMO, they are just not as safe as I'd like a critical component in my rig to be.

This exactly what I wanted to accomplish. I really got tired of using a wrench and destroying the beautiful finish of BP's. In fact, at one point I asked BP to make fittings for us, but they ignored me. So I decided to make them ourselves. I am glad it turned out that way because it forced me to rethink the issue in details, and in engineering, the devil is always in the details.

Hey you don't need that much force on BP, what is hard is to take of the tubing holding without removing the entire fitting, but that is the same to all of them. Just fingers are enough to remove them.
Still these tool specific design is a step forward. But i think using a tool to place fittings is to much, and you are going to damage it nomatter what, but yes, BP design is more prone to get scratches. I scratched mine trying to do that part that i already said, but after it i realized i could do it with my fingers, i wasn't being smart that's all. So no never no any tool on my painted fittings. no...
But i prefer the BP since its more plain looking. I mean that in the good way. Like pretty and not in your face fancy

I've been using a strap wrench (plastic and rubber) to tighten/remove my fittings ever since I damaged a couple with padded pliers. Works OK but due to the size of the wrench I need to assemble many components before fitting into the case. Although I've only used it on chrome finish fittings I know of a couple of people who now use the same tool on black finish fittings without marking them.

"Hey you don't need that much force on BP" : this is precisely where you are missing the point.

"what is hard is to take of the tubing holding without removing the entire fitting" this sentence precisely validates what I am writing below:

Excerpt from white paper:

"All fittings can be subject to a counter-clockwise force which tends to loosen them; in our liquid computer application, this force is usually transmitted by the tubing which when bent in a particular direction may result in a counter-clockwise force against the fitting [..] With compression fittings, the situation gets even worse: this counter-clockwise force is almost always present and is induced by the friction exerted by the collar against the tube when it is being tightened: in effect, as it is being rotated clockwise the collar may grab the tube and create a torsion in the tubing walls; the resulting spring effect in turn exerts the dreaded counter-clockwise force against the fitting, thus tending to loosen it. Let us clarify in all fairness that swivel types of fittings are either less or not subject to this issue, because the swivel relaxes any counter-clockwise force exerted on the fitting base."


I am sorry but I cannot in good conscience endorse your recommendations to tighten fittings by hand. 8 fittings in average x 2 joints each, = 16 joints tighten by hand?
Not for me, not in my rig.

I read those pages and after stewing over it, I do agree with them and what your saying. I just think the aesthetics of these are off from what I see in the pictures. Maybe the nut at the bottom could have be chromed or something?

Sorry about my previous post, I realize now after re-reading it was a bit harsh and lacked the constructive criticism I was going for.


Regarding using pliers on bitspower fittings, I only use the pliers to tighten down the actual barb to make sure the o-ring is compressed. As for the collar, I find hand tight is more then enough.


In relation to the Monsoons, I own them as well, I think their unique tool system works well, its not perfect but it works fine. However, the quality of them is average at best, you can just tell by holding them they feel a bit cheap.


I would gladly be willing to test these new Swiftech fittings if you could send me some. I would post a full review on here.
