This is weird. Need the TXV for 1995 Chevy G-20 3/4 ton Conversion Van with rear air. But the ones I find that are supposed to fit are too large for the lines. The company that made the unit are out of business. I'll upload what pics I can, hopefully somebody will have the key to this one!

The photos are so small I can barely make them out..
I actually have the Parker - Hannifan one sitting here on my desk
Looks like the upfitter used whatever parts they liked.-- Who was the Upfitters
The number one A/C diagnostic tool there is- is to know how much refrigerant is in the system- this can only be done by recovering and weighing the refrigerant!!
Just a thought.... 65% of A/C failures in my 3200 car diagnostic database (GM vehicles) are due to loss of refrigerant due to a leak......
Sorry...first time uploading a picture...the replacement is the Parker....the SE 2301 is the original....the casing has "Advance Air" on it...that company is long gone.
Dang....sure glad I finally got that new 72" monitor to work....wow....and I thought I was the only one with a photo resize problem.....sorry...had to get that 'gig' in.
Understand the photo thing...happens to me all the time.
The TXV issue is not a major problem. Simply measure and determine the correct size inlet and outlet....get in touch with site sponsor and I bet they have one that will work.
I not, post the size requirements and let's see what we can come up with.
The strongest reason for the people to retain the right to keep and bear arms is, as a last resort, to protect themselves against tyranny in government.
Sorry it took me so long to post but I got lost in this thread. This will use a standard TXV our part# 31-10912. Most aftermarket systems will use this type of valve. The one you took off looks like a reverse flow but as long as you have the room you can use either one. Hope this helps and good luck!
Boy !!!....It's a rough crowd today!!...actually, I'm laughing at the huge photos myself, next time you can bet I'll preview this first.
I just came back from Lowes to try and find something to help measure the inlet and outlet on the original TXV.
I must admit, I've never given a lot of thought to the type of fittings these interchange with, its always been "bolt the new in place and reconnect".
What does AC lines/hoses interchange with?...thread and fitting wise ..Gas?...Air?...the closest I could find was a 1/2 inch FIP Brass Pipe Cap and a 3/8 inch FIP Brass Pipe Cap ...both thread on fine...just not "snug" like I feel they're supposed to. I dont know if this answers your question, but, give me a chance, and I'll get the answer for you!
Here are the specs on the part# 31-10912 that I showed you in the previous post
EXP VALVE 3/8 X 1/2MO 12in CAP INT EQ 1.5T
Hope this helps.
Start by identifying the thread pitch, and whether it is inch or metric. You can hold the two valves next to each other and see if the thread pitch matches, then you know at least they're the same standard (inch or metric).
The way you described the valve you took off, sounded like a standard valve like what we use in most of our kits. Glad to help and good luck!!
I can't believe you all picking on a few large images. Fixed by a moderator!
