this is definitely is not hot rodding, but I always come here for help.

I bought an inline ac filter for my chevy van. I thought it would bolt directly on,
but I have to cut the high pressure line and splice it in. I'm definitely nervous
about cutting up my ac line. I'm also nervous about leaks.

Any one have any experience with this?
Thanks
Brian

pressures can go as high as 200 pounds on the high side.what made you decide to get a filter and what does it say in the instructions? You will need to recharge the system and maybe evacuate the system and change the drier receiver if the system is open for a while

It must go in the low pressure line, if you're cutting in. Or, do they include instructions for putting in fittings?

Most lines are aluminum and dont seal well, or tend to crumble when you attemp to use a fitting like a compression fitting on them. Flaring it is out.
Using an AC filter is kind of a patch job. If barrier hoses are deteriorating and plugging up the system they need replaced. If there is other debris like dessicant from a rupture bag in a drier, it too needs replaced, and the system flushed.
The filter is probably designed for install in the liquid line(small diameter line ) .
What kind of issue are you having that makes you want a filter?

The only thing the directions say is "install after the condenser in the liquid line". I'm adding the filter because the system has been open for a while during engine work. I flushed the system as best I could, put in a new orifice tube, and have a new accumulator ready to install. Also, this is a van with rear ac (expansion valve & evaporator), and gm recommends adding a filter after doing any work to the system. There is a LOT more to flush with lines running the entire length of the van. My hope is that the filter will catch debris before heading down the lines, especially if/when the compressor fails. future flushing and repair will be much easier and cheaper, or at least that's the plan. Trying to make a sound decision here.
and yes , it definitely seems like a patch job. If it doesnt work, I'll have to track down a line that is very specific to my van-probably in a junk yard.
I cut the line today. I got a good clean cut, and the line is in good shape. we'll see...

The system was working fine when it was discharged, and I expect it to work again when filled back up. This is a 2001 van.

Thanks for the input.

Your system sounds like it was fine to start with. No contamination. Just moisture possibly. It would be OK with a deep vacuum.
If you had a compressor failure, or hose decomposition , a filter would be a good Idea.Its OK to put one in anyhow. Best of luck.

Thanks again. we'll see. The manufacturer says the filter is designed to
seal very tight.
