Coupler won't fit Accord high side port

shermanreed on Wed October 03, 2007 7:08 PM User is offline

Year: 1995
Make: Honda
Model: Accord
Engine Size: 2.2
Refrigerant Type: R134

Trying to evacuate my system; when I tried to connect my manifold gauges to the ac system ports I could not get the coupler for the high side to go on. It seems as if the port is a different size than my coupler. I am very knew at this - does this make sense?

Are the couplers not universal in size?

Some people do have problems with the cheaper connectors, but also have problems trying to cionnect to the wrong port. Are you sure you're hooking up to the high side? does the low side snap on OK.?? Do you have the connectors that have the thumb wheel or just snap on.. Also be sure you have two sizes, wouldn't surprise me to see the same size couplers...

My gauges have three ports on the bottom of the manifold for the three colored hoses. On the side, instead of having valve wheels to turn off and on, it has a nipple for a coupler. My car's ac ports are also for couplers. Funny thing is, the nipple on the high side of my car's ac is slightly different than the nipple on my gauges' high side. The couplers (blue and red) are different sizes - for high and low sizes. The couplers will work fine on the nipples of my manifold, but the high side will not fit the high side of my car. As I look at the nipple on my car I can see that the lip that the coupler goes over is wider on my car that the one on my manifold. It will not snap into a lock position. Do I need a special Honda coupler?

Here is another thing: I have a set of Yellow Jacket gauges that say they are for R12. Can they be used for R134?

One more thing: Because my car has ports designed for a coupler along with my manifold, should I change out the coupler nipple on my manifold for wheels or should I use couplers on my manifold and car ports?

BTW, my connector couplers have a thumb wheel.

If the fitting looks something like this...it is the correct fitting for your system.....try turning the thumb screw counter clockwise to retract the core depressor...this may facilitie installation

The "nipples" on the manifold are just for connecting an uunused hose to keep them from hitting the ground when not in use. nothing more. Your connectors sound like good ones (Thumb wheels) and they should fit. Turn the thumb wheel as Iceman was indicating, counter clockwise so the depressos are all the way retracted, then connect to the fitting on the car, and once it snaps on, turn the thumb wheel to depress the shrader..BTW One connector os blue and one red like the below pic, right..?? Same as the car, thin is low, and fatter fitting is high with R134a..
