Title: Car air con parts , o-rings
Post by: danishdan on November 03, 2018, 09:36:50
Dump question.

gas is leaking from the compressor via the o-rings that connect the two pipes that come out the front.

What size are these o-rings

and are aircon o-rings different from o-rings you would use on the radiator, for example.

2009 1.6 crdi vehicle.

Thanks

Aircon seals are completely different to water seals, they need to withstand much higher pressures and the waring effects from refrigerant.

Best you take it to a qualified repairer as it's illegal to touch any part of the refrigerant system without a license under the Montreal Protocol, you'll be liable to huge fines if tampered with :eek:

I would have thought the repairer would stock them :undecided: though if they are an obscure size/shape they shouldn't be more than a few dollars/pounds each from Hyundai service parts unless they're the complete hose type with flared nut :undecided:

TW might be able to track what type they are :Good_luck:

Thinking along the same lines as craig you will need the services of a qualified person to evacuate the gas, disassemble the joints replace the o-rings and regas.

Yes the o-rings are application specific and if those are leaking I think it would be a good idea to service all other o-rings at the same time.

Looks like 1 is 3/4 inch 9769034330, the other is half inch 9769034350

I would expect a professional refrigerant tech would have a variety of o-rings on hand all the time and I very much doubt they are unique to Hyundai.

Thanks for the info.

So basically I'll try to find a complete set of o-rings.

for @tw2005 , next time you need to flaunt the convention and replace a damaged a/c component which will already be degassed, you can buy the 'o' rings over the counter in Rocklea.

$120 Vac and regas on Southside too.

I believe the only illegal aspect would be if you worked on the gasses (emptied or refilled the system) - talking UK law here.

You can actually work on the system without qualification but only after the system has been emptied (and later refilled) by a qualified person.

This is made a mockery of as you can buy refill kits from places such as Halfords and attempt to refill the system yourself. A dumb DIY idea IMO.

Anyways, as I'm not doing the job, it's not relevant.

The leak was found by a qualified person, the refrigerant is gone, garage will repair, another qualified person will replace the gas, job done. (regassing prices have seemingly gone through the roof as well)

The Montreal Protocol covers the whole of the EU, I'm quite surprised general public can buy refrigerant gas in a shop there as it's a highly restrictive gas that is Ozone depleting, hence the licensing usually required to sell or purchase.

Generally once refrigerant is removed general public can dismantle a system, though fitting new parts and hoses are supposed to be done by licensed personal as the system requires leak/pressure testing prior to re-gassing.

This stuff is so easy to buy here, but not the way to go.

That stuff doesn't even appear to be a true refrigerant :undecided: looks like a supplementary additive package that can work with refrigerent :confused:

You can get it by the tankful

Question:
Is the tank full of 134A?
Answer:
Yes
By Rund um Auto Seller on 16 July 2018

Some of the ads state "the gas is not R134a. Instead it is a compatible product that can be added directly to vehicles previously filled with R134a "

So who knows.

True, in which case you could easily undo the joint and remove the O-rings yourself , get them and replace or at help to ensure they are correct size.

Over here it's not possible to get those DIY refill kits  :Pout:

Not worth the bother at $100- $120. I pressure the system with air to check my work at my place then
a mechanical workshop gases it for me.
 Drive in early, BS with the lads, go read exciting conventions over breakfast, wander back, charm the office girl, job done, back to the asylum.
The problem with the DIY kit is that you cant vac out before you recharge.
