Firstly, a good squirt of WD40 on them works wonders. Then make sure youâre square behind them so youâre not trying to get them on at an angle. Pull the collar back, push the connector in and release the collar.
once or twice i really struggled with one of the airlines (canât remember which one exactly). Someone has posted many moons ago that his guess was that one of them should go first then the other, again canât remember which one
Yes, I struggle with this sometimes, especially on trailer/unit combinations with limited access to the airline connections.
Some tips:
Switch the engine off before connecting. The lower the air pressure in the tanks, the easier it will be. If you like, press the foot brake a few times to dump some air. Unfortunately, this means that youâll need to build it back up again before you leave.
When connecting the lines, make sure that you have the collar fully pulled/pushed back. No point in trying to push in a connector that will never go in.
The easiest way is to get your body weight behind it, so youâre not just pushing it with your arm muscles. This isnât always possible, though.
Try to find something to brace yourself against - typically the back of the cab, but if thatâs too far away and you can stand on the unit catwalk, try bracing against your knee with your foot firmly planted well back. Then you can use the force of straightening your foot to provide extra force.
Thanks guys, I will try to put my body behind it as I have been standing next to it. I will take any advice you have Priest just so i donât look like a 2Y/O trying to put a square block into a circle hole , donât get me wrong I can get them in but I just look silly when doing it
I struggle Iâm like a racing snake, itâs one thing that did worry me about doing my class 1, but you will find the best way for yourself⌠I lean into it (put what weight you do have behind it) but they is some good advice above mate!
Itâs all about brain, not brawn. Use the bracing techniques described earlier and donât worry about physical strength.
âGive me a lever long enough and a fulcrum on which to place it, and I shall move the world.â
The fleet maintenance guys advise against using WD40 or other chemical lubricants as it damages the rubber o-rings inside the connectors. Also, be careful if you decide to try split coupling. Some sites are okay with it (particularly the refrigerator operators), but many regard it as dangerous and have banned it. Like anything in trucking, itâs only dangerous if you do it wrong.
Iâve heard the comment about damage to O rings but Iâve used it as many years as I can remember and donât remember any issues. I routinely walk round the fleet giving all the appropriate bits a good dousing of WD40 so I believe the benefits maybe outweigh the perceived negative. But thatâs just my experience.
Split coupling is banned on some sites. But, for driving test, its perfectly acceptable if done properly. And thatâs where the stress will really show itself!

very helpful post, isnât it?
From personal experience I have always found it easier to connect the yellow line first. Seems to less pressure on the second airline doing it this way round.
Our maintenance will spray WD40 on the connectors at service time so if they think itâs ok itâs ok by me. Theyâre the ones that have to fix stuff when it goes wrong. I carry a tin with me at all times. Oddly enough I used it for the first time last week having carried it for over a year. Red airline wouldnât snap back until I sprayed some WD on it, then it slipped in like a â â â â â into a â â â â â woman

Itâs not only Suzie Air lines & â â â â â Women, a but lubrication on the curtain ratchets, doors & ratchet straps helps as well, although WD40 is good for a quick fix, Spray Grease will last longer (especially if applied regularly)
Even Spit will help to push a dodgy Airline on (as long as youâre quick enough !)
I was trying to do it today as well (test on Monday) and they went in straight in, I think it was me trying to do it all with my arms and not putting my body behind it. Thanks for all the tips and tricks guy

Yeah donât use your arms as the primary source of pressure. If Iâm connecting to a trailer where the connectors are low down Iâll force them in using my thighs. If theyâre higher up Iâll use my hip area.

Put both Air Lines on first, then the Lecky & ABS line.
That way, youâve got more room to â â â â about, with the rest of the lines out of the way.
