Hello,

Car: 2001 Honda Accord 3.0 coupe 10S17C compressor.

I have one of the supposedly "all inclusive" o-ring kits from 4seasons kit # 26744. While I have the system open, I want to replace all the o ring connections under the hood including whatever seal is under the block off plate with the two allen screws. Is this a standard size o ring or something special that seals this? I don't want to take it apart unless I have a replacement on hand.

PS: Thanks to the knowledge on this forum I have successfully repaired my last car, the first time ever working on an A/C system, and since I did it "right" without short cuts-under this fourms advice- the a/c system worked great for 4+ years since without a hiccup! So thank you all for your help.

Just as an update to my own thread-The block off plate pictured has a standard sized o ring sandwiched underneath it, I forgot the size but the all inclusive kit has many that size already included. Its not a special seal or anything so replace it without hesitation!
