if the drier is an old style which is one that is between the block style expansion valve and the low and high combination block style line then their isn't o-rings, if it's a newer style probably is then you will are likely to find O-rings where the drier is connected. Anyways becareful around 134a, though not harmful it is less dense then air so you can actually die of asphixation.
