This is for my 2000 Honda Civic Si. I need a new O-ring where the hose for the air conditioning condensor hose plugs into the top of the condensor. Its the part right in the front of the engine bay near the center right under a 10mm bolt that holds that high pressure condensor hose on. I don't have a good seal there cause that O-ring got pinched once. Anyways, just wanted to know what size that is so I can go get a new one that fits. thanks

 

It should be a 1/2 INCH O-Ring

 

well dang, i called the dealership told them what i wanted and he said they have it. my friend picked it up for me but it is way too small to fit on that fitting. so does anybody know what size or part number that is? thanks, maybe i'll just ask for a 1/2" O-ring instead of telling them exactly what part its for.

 

Go to the dealership and point out the one you want yourself. They have them.

 

Here's how it goes on the A/C lines connecting from the Compressor to (H) Condenser and Compressor to (L) SUCTION Hose:

(H) Pressure side Hose = O-RING (1/2 INCH)
(L) Pressure side Hose = O-RING (5/8 INCH)


............... If you still are unable to obtain the right O-Ring size here's the deal there's only three sizes: 8MM O-Ring, 1/2" O-Ring & 5/8" O-Ring. Of course 8MM being the smallest ring.
