| voss vs aftermarket pushfit |
|
hi guys
hope this isn't too much of a daft question to ask 
got a new reservoir valve and air tank
am very tempted to instead of using the voss connectors but fit some aftermarket pushfit into the reservoir valve instead
basically for
ease of fitting and not having to mess around with the olives
far easier to remove the pipes for future if required
know that when the pipes are pushed in they won't come out
not having to mess around underneath the landy,
ref the voss, are they 1/4 inch bsp to 6mm please
thks guys and hopefully u don't think i'm barking , oh hang on , i am already arnt i cause i own a disco

Plenty on ebay.
We use pushfit all the time at work the plastic ones arent as reliable as the brass ones, in fact one truck maker went as far as saying any pushfit type is only a roadside get you home repair, everyone ignored them and carried on as normal!
Voss was pretty much std fit on all trucks for many years but even they seem to be going plastic now.
Iirc theres several different style of voss fittings.

thks for the help 
didn't realise that ref the voss connectors , would be ideal in getting brass with a pushfit fitting
can i be a pain and would u be so kind to tell me what size i need please
for the reservoir valve
trying to remember what connector is on the reservoir air tank
also got a new inlet and exhaust silencer
at least then when i had cut the old pipes to fit the new compressor , by fitting a new silencer will also be all new pipes
thks so much once again,

looking at these voss connectors
does this make sense
that the voss connectors , size wise are
6 mm x m10 x 1
6mm pipe, m10 thread diameter and 1 being the tread pitch
cheers guys

That how I would read it size wise

thks
this is what i found
what do u think
http://www.advancedfluidsolutions.co.uk/6m...2875-p.asp
so that i can take out the voss connectors from the reservoir valve i'm going to fit , saving me messing around with the olives etc
also cheaper too , easier to remove the pipes if required, plus can fit these connectors before fitting the valve, remove the old olives of the plastic pipes then push them all in,
without worrying about cross threading etc
will measure the depth of the fitting first to ensure when i push the pipes in they have indeed seated correctly

I always use some high tech lube on nylon pipe when inserting it into a quick fit union, spit

| Push fit -v- screwed connections |
|
Push fit versus compression fittings....These are commodities I have used for many years with compressed air & other gases.
Push fit....easy but not that robust
Compression Fit....tough & leak free....even on hydrogen
The very best are Festo....simply they don't leak, have a superior grip system & have the correct length tsoervifvthread to engage the internal port.
I've tried all of them:
Legris.....who innovated the push in
Norgren (used to be Enots.....actually Benton & Stone ....Enots is stone reversed)....good quality
SMC....daft make thread system that doesn't work that well
Swage-Lok......high priced compression
Guest.....rubbish
We tested Festo when we needed push in to work on reducing atmosphere soldering furnaces....which use vacuum (not all push fit "do" vacuum), nitrogen & a mix of of hydrogen & nitrogen...forming gas which is used to find leaks in important complex systems.....anaesthetic machines.
Festo passed all our tests....without fault.
If you need to buy - try Brammer or Eriks BREXIT - done properly.
Right now ...We need Government - not Politics

cheers for the great info
suppose i've been useto underfloor heating fittings and understand difference between cheaper made ones
also of course compression fittings , not many systems made hydrogen , not did i get involved with compressed air
will indeed check out the sites
going to make life easier in the long run, also going to ensure i install pipe inserts
will be the metal push fit ones, instead of the ordinary plastic ones
also ones that allow u to remove the pipe as i know some, u push the pipe in and that's it, no way of removing them , which is defeating the object of what i wish to achieve
know that other problems can occur when the pipe arnt pushed into the fitting correctly
looks like i've got some reading to do
always like to check things out before hand
yeh i know need to get out more
thks again

All these need is:
Pipe cut "square"....any out of squareness really affects things
Shouldn't need any lube..all it going to engage with is one or two "O" rings
The pipe is retained by a barbed fitting......most inducpstrial ones can release the pipe by pushing tha coloured ferrule..
Never use pipe sealants or silicone with push-fit fittings
Personally I'd always use a compression fitting if I wanted it to stay in & leak free...usually these come in brass or plated brass.....you can get stainless (Swage-Lok) these aren't cheap. BREXIT - done properly.

thks for the heads up
spent some 25 x years as a heating engineer and agree that if the pipe isn't squared off correctly can cause all sort of problems
have always used either silicone grease or washing up liquid, stops the risk of o rings being pushed in
but never used any sealent
have used the likes of upinor , but know thats for underfloor heating etc
there is a lot of pushfit that are complete rubbish , however done a few 40 x zone underfloor heating system with good quality fittings
all about as u day say making sure that fitings are installed correctly
trouble is with some compression fittings is they don't like movement much , inc the expansion and contraction , nightmare if the olive hasnt been seated correctly

Compression are fine if they have a support tube inside the pipe, if not avoid, the quality brass push fits have the support built in.

will be good to finally get this lot sorted out
with doing little bits here and there
having former experience of central heating and underfloor heating systems, get really good at finding leaks etc
will set up a small manifold and test each line
it won't beat me that's for sure and make sure it knows who's boss
well until i turn my back and have a surprise in order ,
it is a land rover after all

That's a wicked idea having just cross threaded my front valve this would of worked great. Ordered a new valve for rear which has voss connectors on already so I'm assuming they are push fit aswell if my one happens to Know fitting it in morning
