Review on High Performance Four Seasons 38641 Orifice Tube for Enhanced Efficiency and Reliability by Enes Patiag

I bought this when I was rebuilding the air conditioning on my 1994 Jeep Grand Cherokee. Unless you are an air conditioning technician, do not buy this. For the 1994 model (and possibly similar ZJ models) you will need to purchase a complete fluid line that includes a hose with an orifice. You can't just line this up, you need special tools to take out the old bore tube and crimp this. Revain should not sell this part for this vehicle. At least it was only $3 wasted.
