I don't know much about Diff Breathers but I do know they're pretty much essential. I've been looking around for kits, trying to avoid using garden hose.

Have come across this kit, just wondering if the hose in it is the right diameter, as i have no idea..

Thanks in advance. :)

dont use garden house. use fuel line. bought from your local super cheap or repco etc,

look at Jason's (want33's) build or Rushos or mine.

few pipe clamps, some fuel line, and some fuel filters, easy and really effective

as for your question about diameter... I dont know, tape measure or wait for someone on here to respond

There is nothin wrong with good quality garden hose, works fantastic on mine and is the perfect size for all the breather nipples. Plus you can get plastic angles, etc... for it.

Im using garden hose... rather save my money for other shit.
Oh if you want to remind me to post here in another 5 yrs time when the garden hose fails (supposedly). I can then whip another bit off the end of the hose.

Like rebuilding the diff that failed because of the broken breather.

PVC breathers do fail. I've seen it. It takes less than 5 years. Garden hose is for gardens. That's because gardens aren't oily. OR hot and oily, and in any case, how many times have you had to cut back and shorten a garden hose because the end at the nozzle went stiff and the coupling fell off, and that's only in a garden, not under your car.

Whatever. The OP knows what to use.

bit of a high jack but what fitting is needed to be screwed into the diff to attatch the hose to

Post subject:  Re: Diff Breather Query..
It's normal to just pop the cap off and slip the hose over the stub that remains attached to the diff - that's why people use garden hose - the approx. 1/2" bore slips over the stub pretty well.

If you want to get bling, you can cut the stub down a bit and tap it with a 1/8" BSP tap and then use a proper brass fitting and smaller diameter hose. This is more work and raises the possible issue of steel shavings making their way through the diff.

Hutch - I don't need to "prove it"- It's science. PVC is not oil resistant. Ify ou want to do the experiment, pop some garden hose in a jar with some gear oil. You'll be surprised how quickly it goes all funny.

ok Ill prove it
brand new nylex premium hose on my diffs has cracked in less than 18 mths.And the rest in the garden is still nice and soft.
oh yeah it was new when I fitted it as I chopped it off a new coil I bought for the house.
your diffs do what you like, but I can assure you there is no pvc hoses on your car from factory.

OK I will try that experiment. I will take photos along the way to. :P

My point about tyhe garden hose was it is cheap and easy to fit and that commercial diff breather Kit for $100 would buy a shit load of gaden hose.
Just a side question... why does ARB use PVC hose on their airlockers? I have ARB lockers both front and rear and both aree blue PVC hose. I spoke to the ARB head mechanic and he stated the Hose idea was bloody great. He stated it was a muche better option than rubber hose which perish.

hutch I dont think that blue air line is pvc.
it a nylon type thing I think.
my cherry pickers use a very similar product to my air lockers and its definately nylon on the pickers.

TMP II by this link is what you need

looking forward to gmans explanation as to why this PVC hose is widely listed as fuel and oil safe, its Science afterall

Post subject:  Re: Diff Breather Query..
The composition of the clear inner tube isn't specified. It may well be "pvc" but it might not be too, even though it's referred to as PVC hose.

Your point is a fair one Royce - but you've read an application guide and chosen a suitable product. That's not going to bunnings and grabbing a reel of garden hose and then claiming it's the best thing to use because it's cheap.


Steve.

PS I've seen clear PVC of that type used and I'm not crazy about it's flexibility. Id be using a barb and 6 or 8mm diameter hose if I was using that type of PVC from my experience- it's easier to fit and holds tighter radii without crimping.

Post subject:  Re: Diff Breather Query..
there is no inner liner on that stuff, thats why its not listed, I dont think its oil that kills garden hose, its the heat cycling

if you go to teh right place this stuff is $1 a meter so cheaper than garden hose, it will stay put on teh factory diff 'tail' really well too, the hose doesnt really deform and it doesnt soften with heat

Not picking an argument Royce, but from the app guide, Coldflex, TMPII and Garden hose all have the same temperature range. 0? to 60?

I think it's quite reasonable for a diff to exceed 60? - I know my shaved vitara rear diff gets way to hot to hold your hand on after cruising.

I agree the heat cycling is an issue, but there must be a difference in composition for the TMPII to be rated for oil. Note the outer and inner are both listed as "clear" for the TMP II, that doesn't mean they aren't different compositions though.
