Do Ineed to put zip ties at all of the robart air line connections &amp; T fittings? or can you just slide the line in and be good? Iput zip ties on some of theT fittingsand oneline started to leak, took the zip tie off and no leak. So what's the best way to make all the connections?</p>

<div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; padding-top: 0px; padding-right: 0px; padding-bottom: 0px; padding-left: 0px; background-image: initial; background-attachment: initial; background-origin: initial; background-clip: initial; background-color: rgb(255, 255, 255); font-family: Arial; font-size: 12px; ">I have many air retracts and all are just pushed on, and none leak (at the connections anyway).<div>
</div><div>Putting  a zip tie on will distort the plastic, pinching it where the zip tie head is, thus causing the leak.</div><div>
</div><div>I have never had a hose pull or blow off.</div><div>
</div></div>

I agree Zip ties will not give uniform pressure, Right at the head the plastic will always have a small 90 degree bend, That bend will be looser than the rest of the zip tie.

Now I've used these [link=http://www3.towerhobbies.com/cgi-bin/wti0001p?&I=LXET33&P=SM] Little guys[/link] for a little piece of mind, but I've also has systems not leak for years with out them.

good luck

That's kind of what Iwas thinking but wasn't for sure. Thanks guys Iwill take the few ties off.
