Re: Low side hose pinches when pulling a vacuum

Further research online tells me it's nylon inner hose with fiber braided on the outside.

thanks for all the help...

Re: Low side hose pinches when pulling a vacuum

I pulled the ac hose off and did find hose info which is not that legible but am able to make out it says the following: R134A/R123yf other info is faded. Looking at the hose material it's a nylon based covering or not the typical hard rubber I see on other ac hoses, or whatever the outer material i...

Low side hose pinches when pulling a vacuum

Just received a new low side suction hose (GM GENUINE 1522310). When installing it I noticed it felt soft and very flexible. When pulling a vacuum it pinched the two hoses on both sides of the muffler. This is very odd, never seen this before. In looking at the picture of the hose online, it shows l...

Re: 2014 Silverado 1500 AC Trouble

It held a vacuum for well over an hour. Vac pump off. I'm pretty sure there was no leak. How I filled it with R134A: With it under vacuum psi, engine off, I turned a 12oz can upside down and let it in the high side. until the gauge needles went above 0 and low side was up to 20psi or so. then I turn...
