My car has a tiny leak in the low side hose for the AC system. Is there a safe way to seal this tiny leak?

Question

The leak is easily accessible under the hood, it is on the low side hose and is very tiny. Does anyone know of any sealant that would be safe to use on it, or is it necessary to replace the entire hose?

Answer 1

put sum duck tape over the leak lol (dunno) take it to a garage and ask them

Answer 2

There is nothing you can use that wont wind up costing you more money in the long run. They do sell ac sealant but I dont suggest using it as it cloggs other parts of the system. As far as 300 dollars, that sounds like its a fair price. Most hoses are not cheap. Maybe you can buy the part yourself and have them install it with no warranty, that might save you a little.

Answer 3

it could just be a 0 ring. if it is, then a can of ac stop leak might stop it.

Answer 4

Replace the hose and recharge the system.  There is too much pressure on those lines to successfully repair them for the long term, even if it is the low side line.

Answer 5

I am not a mechanic, but $300 sounds outrageous.  Replacing an AC hose could not be that more difficult than replacing a radiator hose.  The hardest part I think would be finding enough room to get your hands in there to work around it.

Then  buy a recharge kit and a can or 2 of freon.  The freon and the AC hose probably won't set you back more than $50.  The shop you went to will probably give you some line about freon and saving the environment etc..... but you probably don't have any freon left in your system to lose anyhow.  

Try it yourself first and see what happens.

I imagine you can buy the AC hose at Autozone and you could probably get the freon there too.  I know you can get the freon at WalMart as well as the  freon installation kit you need as well.  A kit costs 20 bucks or so.  It is really easy to do, just hook the hose up to the insert valve usually in the back of the engine and watch    the gage and stop when you get to the red zone.  It is worth a try.

Filling your car with freon is as easy as filling your car with air.  Same principle, except the air is freon and it is in a can instead of a machine at the  7-11.

you did not mention the car you have, but I bet you could probably find  a video online illustrating how to change it.  This could help you determine whether it is something you want to tackle.

Answer 6

Are you sure that it is freon that is leaking from that hose and not just condensation from A/C use?
