How to detect air leak and replace the o-ring on Volvo Vnl Kenworth Piterbilt Freightliner Mack 

Man I have thrown away thousands of dollars of those fittings over the years never knew you could rebuild it. Thank you.

Thank you driver. I am Owner of 2019 Cascadia. I didn't know before about O-RINGS. THANKS A LOT

Thank you. Didn't realize there was an oring in there. Great zoom in picture

Just what I was looking for great job 👍

Great video. Very important what you said about buying them rings at dealer. I tried online and auto parts store but they all leak.

Driver I believe a Cascadia has same fitters, just different position. But THANKS A LOT. I got at Home Depot an O-RINGS 1/4 of sizes.

Thank you sir for teach us, exactly I have same air leaks in my volvo trucks and know I know how fix it

Great job . Thank you

Thanks very helpful video.❤

Good work,enjoyed!

thank you 👍

Nice video Thank you brother.

You r the king broo I share you broo

Thank you

What did you used to cut off the air hose ?

Is the brass part you pull out replaceable I accidentally broke mine.

Hi good video do you have part number for 3/8 line O ring ?

Hey boss do you know the fitting part# thanks

What's up man ,so I jus need to change the rings huh

Hey I bought o rings by the part number on the video but they looks too big

Is there a any other part number?

Where is the part number?

Some of this fittings have a metal or plastic little fingers inside to grab the hose and i don’t know if it has a O ring pass the little fingers that will be difficult to do
