Converted my 93 seville to r134 but didn't flush the condenser as has been recommended. (read that after I completed the job) after 3 replacements of the orifice tube it seems to be mostly clean, but I would like to install a liquid line filter anyway. can get a flared connection type filter dryer from an industrial supplier for $10, but worried about being able to flare the aluminum tubing of the high side line. Auotacreapairs.com has a compression fitting filter for $60, but it is awfully small, yet cleanable.
any thoughts or suggestions?.
