Barry : Welcome to the HellermannTyton ACADEMY, the workshop for the professionals.
I´m Barry.
Mark : And I´m Mark.
Barry : Today’s question is around fluid-resistant tubing.
We’ve been asked to demonstrate our fluid-resistant tubing SE28.
Mark : So Barry, I will do this demonstration, for this video.
Barry : OK.
Mark : Right, so we’ve got some cable here, …
Barry : OK.
Mark : … so what we need to do is to get rid of all the grease off the cable, ...
... off people´s hands, and things like that.
So if you could pass me an alcohol wipe please Barry.
Barry : We did that on our previous video on HMTA , didn’t we?
Mark : We did that on our previous video on HMT200A.
It´s really important to get rid of all the grease, it’s a very important part of the process.
Barry : And if you haven’t seen that video click on the link below.
How do we know it´s the right size tubing Mark?
Mark : We know it´s the right size tubing Barry, because ...
... we´ll actually measure the ID (internal diameter) of the cable …
Mark : … and then we´ll get the tubing. This tubing actually shrinks, it´s got a shrink ratio of 2:1, our SE28.
Barry : So this falls into our 80/20 rule?
Mark: It does fall into the 80/20 rule.
So the 80/20 rules means that we have a tubing that will shrink just slightly more than the ID you want.
So if you’ve got a tube... a cable, that is 10 mm, really you want a tubing that will shrink down to about 8 mm …
… so it forms a nice grip on the cable.
Right Barry, could you get me a stand please?
Barry : Yes.
Mark : For this demonstration we do need a stand.
Barry : So we don’t talk, we do.
Mark : Alright, so if you put that in there.
Barry : Captured.
Take your time Mark.
Mark : Thank you Barry.
So it´s securely in there. Now what I actually need is some protective wear, ...
... so I have some goggles.
Barry : Why do you need protective wear Mark?
Mark : Barry, we going to use a hot gun.
The hot gun operates at about 250° Celsius so it does get rather, rather hot ...
... and it can be a little bit dangerous if you don’t know what you´re doing.
So we have our hot gun , our HellermannTyton hot gun, ...
... we have a nozzle, a deflector nozzle, ...
Barry : Top tip. Mark : ... that we also use.
Barry : When you shrink tubing, use a deflector nozzle.
Mark : The reason we use a deflector nozzle, …
... I´ll just demonstrate it without the deflector nozzle,
we´d be trying to shrink around like that.
With the deflector nozzle we can put it on and then we can start to shrink.
Barry : So it radiates the heat all the way round the tubing?
Mark : It does radiate the heat all around the tubing, Barry.
Barry : Do we have these in our range?
Mark : We have these in our range, yes.
And you can also buy them separately.
Now I am starting in the middle Barry.
Have you noticed I´m starting in the middle?
Barry : I have noticed Mark, yes.
Mark : So this is a way of making sure that your tubing is positioned very well on the cable …
Having the deflector nozzle also means that you can actually a lot quicker onto your cable.
Barry : So what wall thickness is this tubing Mark?
Mark : This wall thickness Barry, it’s a medium wall thickness.
A thin wall thickness tubing would shrink even quicker.
Barry : So this is a specified tubing? Diesel resistant? Fluid resistant?
Mark : This is a VG-specified tubing.
So it is a specified tubing.
Barry : So there’s a top tip: VG tubing always has markings on it every 25 mm.
You’ve done a very good job of that Mark.
Mark : Thank you Barry.
Barry : So how are we going to demonstrate ...
... the fluid resistance for the customers and the people watching the video?
Mark : Well Barry, if we get rid of the stand, I´ll let you know how we´re going to demonstrate this.
Barry : I can’t wait
Mark : Right Barry. I have, over on the bench there, a tub full of diesel , …
Barry : Excellent, …
Mark : … straight out of your car, ...
... so if you would like to get that please. Barry : … I´m walking home tonight then.
Mark : You´re walking home today. Barry : OK.
Barry : What are we going to do with this Mark?
Mark : We´re going to prove our tubing Barry.
So this is our cable with our diesel-resistant tubing on it …
... so we don’t promise, we prove.
Barry : So what does that prove?
Mark : That proves Barry that our tubing is diesel-resistant.
It can stay in there. There will be no deterioration of the tubing in there.
It won’t swell it won’t come off, and it can stay there, it’s impervious to diesel.
Barry : So tubing that isn’t fluid-resistant would swell.
Mark : Tubing that isn’t fluid-resistant would swell. So this is our SE28 Tubing.
Barry : Excellent, well done.
Mark : Thank you Barry.
Barry : So if you liked our little demonstration today, please like us and subscribe to our channel. I'm Barry, …
Mark : … and I’m Mark.
Barry : … and we´ll see you again soon.
Mark : Bye.
