So you want to install tube fittings. In this article, I will explain to you how to connect tube fittings otherwise known as; compression fittings accurately and securely.

Every time to make sure it’s safe for you and your workers before we install a tube fitting. We want to make sure that the tube is properly prepared. So we want to make sure it’s clear; that it’s deburred and that the tubing harness matches the tube fitting specifications. Always check with your manufacturer; to make sure your tubing is certified to work with the tube fitting that you happen to be using. There is one big myth that is common in the industry and that’s when we’re tightening the tube fitting; that a two fitting can be tightened and it’s a matter of torque.

So, Did we get the torque right?

Did we tighten it up? and Can we feel when the torque is right and know that a fitting is tightened correctly?

Big myth and big misunderstanding. In reality, a tube fitting nut is tightened on the stainless steel tubing; by the depth that the nut is tightened to; or a number of turns from hand tight. Today I want to tell you how to tighten a tube fitting properly on the tubing.

So we make sure to have a leak-free safe connection every time there are standard guidelines. For installing virtually every tube fitting on the market and they’re all the same no matter what brand. Of all the major brands in the market; a piece of tubing is inserted into a tube fitting until it bottoms out; there’s a shouldering the back of it that we’re going to bottom this tube fitting out on. It’s very important that we’re going to take the nut, and we’re going to hand tighten the nut; until we can’t hand tighten anymore at that point a marker is needed. We will mark the nut at the six o’clock position; along with the body with your marks at the six o’clock position. We will continue to rotate this nut; with a wrench one and one quarter turns from hand tight six o’clock position.

One and one quarter turns brings it to the nine o’clock position and that’s it that’s as easy as installing a tube fitting is but there’s one other thing that we have to do which I see in the market that not many people do every manufacturer has in their instructions that after a two-fitting is installed we must then use the gap gauge to check the gap between the nut and the body.

So there may be a gap when we finish tightening this nut correctly there’s only one spot that will give us the maximum sealing potential for a safe and sure connection under-tightening causes the ferrules inside not to bite which can at pressure releases tubing making it become a project leaver tightening can crush and damage the ferrule sit can crush the nut and cause leakage.

So, We want to make sure that this nut is tightened to the precise spot every time so what can happen if we install a fitting that’s over-tightened or under tight first of all you may have to throw away the fitting a tubing run might have to be replaced which causes a lot of time and expense also more concerning is the potential for safety issues so the media running through our tubing may be at high pressure it may be at high temperature and it might be caustic chemicals which could be harmful so anytime we increase the potential fora leak we’re looking at serious consequences.

Now, I want to tell you an amazing new patent which limits the potential of human error which is what we’re dealing with today is installing this correctly is the human error factor this is a new patented tube fitting from Realfind. What Realfind has done is put built-in gap gauges on every fitting because most installers are not using the gap gauge to check a fitting and make sure it’s done correctly.

So I’m going to remove these ferrules and give you a demonstration of what a gap gauge fitting does with Real Find Trading you take the tubing you insert it into the fitting fully and you start tightening the nut you tighten with a wrench until these red rings pop away these red rings are amazing new built-in gap gauge what this does is eliminate the need to carry a gap gauge and most people in the industry are not using a gap gauge to install fittings anyway.

So they’re really not following the manufacturer’s instructions now we’ve eliminated the need for a gap gauge by having a built-in gap gauge on every fitting so the distance is always correct it’s not over tightened and it’s not under tighten it’s tightened at the exact right spot every time for maximum seal and safety this simple patent is rocking the industry.
