Hose fittings leaking

[twojaythomo]

We I thought I would lash out and get some nice brass clip on hose fittings going to join my 2 condensers well how I was wrong they both leak and my cheap plastic SAMs wearhouse ones do not, why did I both, don't know

tjt ..try a different O-ring .
You can buy sets of these and often a slightly fatter one will help .....so will a smear of Inox grease

I did the same as you, they really leaked once they warmed up a bit.
I went back to plastic as well.

Try wrapin a few turns of thread tape in the o-ring groove ,then replace the o-ring ,I found this tightens and stops leakin fittings .my thought is on some fittings the o-ring groove is cut slightly to deep,cheers hillzabilly

Or you could try air fittings, that's what I use and have never ever lost one drop of cooling water. :handgestures-thumbupleft:

Once all is running smoothly will definitely give the thread tape a try, didnt even think of that thanks.

As a landscaper I have found the Holman brand of brass fittings to be fine ,some others have plastic parts inside .cheers hillzabilly

Old thread, but in my latest build I forked out for a set of Gardenia brand plastic hose fittings (the more expensive ones from the big green box).

They leaked at the O-Ring when under pressure, despite the advertisement.

Ended up wrapping the spot with 3-4 rounds of Pink Tape and then placed a Holman brand O-Ring over the top. A little more stiff to clip on, but no sign of leaking yet (One complete run done).

Someone recommended a set of various size O-rings from the plumbing section, so possibly using a slightly bigger/thicker one. Did not pursue due to finding a solution for now.

I would also rec a little saliva or water or o-ring grease on the o-rings when ever you set up the fittings this helps them ta seal properly,otherwise the o-ring can be damaged,cheers hillzabilly

I've never had a garden hose fitting that worked for very long. In the end I used controller air fittings which are much more reliable:

:text-+1: :text-imwithstupid: Perfect IMO, never had a leak. :handgestures-thumbupleft:

If you've got a beer interest then keg lube and decent O rings fix all the leaks I've ever had.

The Holman whilst looking robust in brass aren't much better imho.

These air fitting sound ok ... guess time will tell

Are you going to try them bt1?

Time has told. ;-)

1 2,

I don't have a leak issue but it sounds like you've been using these for a while, in which case when needed seems like a good idea to progressively change over.

btw What are they worth, do you have a brand/retailer preference?

cheers

I just ordered of Ebay and so it will be a Chinese job, but you will pay about $2 to $ 10 per elbow, from no brand to something like Festo, Norgren, or John Guest.

But I did pay for the hose that was about $5 a meter, and is thick walled so internal diameter is only 9 mm, the good thing is it stands up to the heat so the tube doesn't get floppy and sag, it stays quit rigid. :handgestures-thumbupleft:

I've used SMC and Festo on the job, great stuff.

There's quite a few tube material options, you must have the nylon bt1? There's also poly which is quite a bit softer but easy when bends are required.

I've got heaps of 6mm if anyone needs any. You guys using 10mm?

12 mm outer 9 mm inner diameter, I just asked for high temp hose :handgestures-thumbupleft:
