That is correct. The refill kits you can buy at walmart only fit the smaller port.

 

Also make sure you keep turning the bottle upside down/ right side up while doing it. Buy one with a gauge on the hose so you can see when it's time to stop filling it. Make sure you read the directions as well. don;t want anything adverse happening to you while refilling it.

 

Don't turn the bottle upside down. You always want the valve at the top. It can be at an angle, but not upside down. You want gas, not liquid going into the system. Upside down you risk a slug of liquid cavitating. If you're in a hurry, put the bottom of the bottle in how water. I've only seena slug of liquid crack a fitting once, but it can happen.

 

Yes and one other thing I can tell you is that some R134A cans are now self-sealing now require an adaptor DVA-1 if you are used to using the piercing type gauge and hose set. (Thanks to California regulations it ended up on our shelves here in Florida). At least the adaptor is not very expensive.


Self Sealing R134A cans may require this adaptor if you are used to the needle type piercing gauge set

 

Leave it to California to screw the rest of us over.

 

Exactly.

 

Kalifornia is more worried about being SEEN to do something than really accomplishing anything. Rather than let wear and tear take care of things, they are now outlawing older large trucks. Trucks I drove in the early 70's are either off the road, scrapped and made into Chinese refrigerators or in truck shows. That's not good enough for the bureaucrats who have to justify their jobs.

That's for Semi's, not pickups. Still and all, I bet you see a lot of trucking companies moving their headquarters OUT of commiefornia....... 10 years is nothing for one of those trucks, and buying a new one, or repowering your old one, just ain't cheap. End up spending less relocating the company......
