Just got my new bags today from Rovacraft. They're Britpart bags & have the same look & feel as the originals, unlike the arnotts. They both have contitech rubber but a different feel.
Question about the fitting, like a few posts before, they recommend cutting the line. So, is that it, cut the line & push the line in the bag?? How does it stay there? The arnotts you unscrew & screw the new one in. I just feel nervous cutting the lines without knowing how it works:p
Thanks, Dave.
The push in fitting have a circular drectional type collar which locks on to the outside of the tube providing retention. Imagine hose barb or fitting on your garden hose. An o-ring then nprovides the sealing.Quote:

The push in fittings recommend the trimming of the tube to remove the distorted part of the tube caused by the original compression of the olive. This then gives a smooth round area for the retention collar to lock onto and the o-ring to seal against.
Trim only what is needed.
cheers
So if it's all done right, once I push it through, I shouldn't be able to pull it back out? Does it matter if the bag is inflated or deflated?
Thanks strangy!
Ouch.. wish I'd had a bit more time.. I spent $590 at Airbagman on the dunlops. But i guess i couldn't have put up with riding on the stops too much longer *sigh* :(Quote:

I believe (please correct me if I'm wrong here) that if you push the silver socket in while pulling the air line out it will probably release it. I felt a bit apprehensive about the whole push-in connection.. but it seems to be sweet. :DQuote:

:Rolling::Rolling::Rolling::Rolling:
What i think i meant, was if it was deflated should I try not to pull it out. Something along those lines:eek::eek:
I dont have an outer collar release (i dont think) it looks the same as the Arnotts screw in type. Heres a pic.
Ok if the picture is what you have, then you seem to have screw in fittings. "Did these say they were push in"Quote:

Leave the small plastic plug in (so you dont lose the olive ) and unscrew and you will see the olive. Push the tube in and make sure the olive is over the tube and not sideways etc. It should sit about 5 to 10mm from the end. Tighten (not wrenched) leak test and you are away.
Well that's what I thought, I have done this about 6 times before because the arnotts kept on leaking.
Now my instructions say to cut the line, this is why I have been so apprehensive to cut the line. It looks no different to the other fittings. I would have thought it would have been a different fitting. They even have paint on the fitting so for warranty purposes they know if they have been unscrewed.
"the air connector in this part is a sealed unit & has been extensively leak tested. Removing or loosening the connector for any reason will destroy the integrity of the seal & the part will no longer be guaranteed against pressure loss or failure. Bla bla bla..
Anyone got a pic of their push in type?
Push in fittings are round and have no flats to fit a spanner on. The silver bit is the push collar and nd th brass bit is screwed into the top, sealed and marked not to remove. etc. Hope this helps. I am 99.99% sure you have screw in fittings.
cheers.
It looks like a push-in fitting to me. Looking inside the fitting you can see a seal rather than a nut and olive arrangement........I think:pQuote:
