Reduced barrier vs: regular

JR911 on Mon May 19, 2008 4:27 PM User is offline

Year: 1986
Make: Porsche
Model: 911
Refrigerant Type: to be 134a
Country of Origin: United States


I'm replacing all my hoses but need more info to make my decision wether to use the reduced dia. or reg. barrier hose. Remember on my car there will be about 40 feet of hose, mostly exposed to the road below or in the engine compartment, so I'm questioning the durability etc. on the reduced dia. hose. Pros/cons??

I will be ordering a new receiver/dryer but the standard replacement typically would have been used w/R12 and I'm going to 134a. Is this an issue or not?

Thank you,

Only benefit of reduced barrier is space. Reduced is mostly used on busses and such where they what to feed the lines through frame rails and so on. If you have the space standard hose would be my choice.


When considering your next auto A/C purchase, please consider the site that supports you:

Reduced is easier to work with. I just replaced all my hoses on my 1987 911. Tight spots that you will appreciate with reduced include running the lines into the engine compartment by the shock towers along the engine pad. Had to cut one of the orig hoses to get it out - new hose pulled through easier. Addl tight spots: (1) drier to front condenser behind the washer bottle (2) evap connections and the front fender particularly if you add a ProCooler as you will have two addl lines to route neatly and tie down.
