67 Dehydrator/Drier Sight Glass Cap

[Kirk M.]

Have a question for you. I have a 67 drier mounted in my car. As you can see from the picture (picture 1) it has a hex shaped sight window. Recently found one of the "rare as hens teeth" sight glass covers (pictures 2-4). As you can see it is round. Tried to put the cap in the window and it didn't fit (like a square peg in a round hole). Is this set-up correct, or do I have the wrong cap? Does it just "jam" in? Thanks.

Kirk -- have never seen a hex fitting on the widow. Here's a service unit I ordered early '80's; you can see the brass slots in the fitting. I've never unscrewed the cap/cover but will do and photograph if it helps.

P.S. I have what I think is the original drier in my car and another spare that was given to me. They all have the brass fitting with a slot on each side.

I'm with Wayne, never seen a hex on a midyear.

Unless I miss my guess that is made by/for Four Seasons and either sold under their brand or maybe another brand. The shape of the cannister gives it away.

Take home message is drier is wrong, plastic cap is good. Dang it.

In 63 I worked in the A/C repair dept for a Chevy dealer. I saw BOTH types of driers. The only plug used, back then, was a red tapered plug with a lip. On unmolested driers, it would have been painted flat black along with the drier.

I would agree with Ken - the 67 has a round glass with the red tapered plug painted flat black.

Ken - Very interesting on the '63 A/C drier sight plug being red and painted black. Unfortunately, the only example of an original A/C drier I have seen did not have the sight plug; but I've seen numerous post 1963 production A/C driers, used and NOS, with sight plugs in place and must admit I've never see a red one when I've removed them for the drier; but now I have something new to be looking for. What are the words in that song "paint it black, black as night." Pete
