Hi all, I’ve developed a new air leak, where rear left bag is deflating in about 12 hours. I’ve soaped everything and found a slight leak where the pipe enters a push fit connector (previous repair) near to the valve block. This is after a full valve block and compressor refurb so a bit annoying!!!

so far I’ve trimmed it back a bit and used a new connector but still getting a slight leak. Any tips to get these old pipes to seal please? Short of replacing the whole run with brand new I’m stumped.

Thanks

It is 6mm od and 4mm id nylon tubing. Not that dear from a main dealer. They just cut it off a roll.
Don't use polythene or polyurethane tubing. It is too soft. Use nylon.

It is high pressure air line as used by spray painters...a tools shop should have it, and the connectors. Your o-rings may have been damaged by the previous repair...chamfer cut ends (clear any swarf) with a pencil sharpener and lube with detergent liquid. No need to replace entire lines...any number of cut-and-shuts can be done if quality connectors as linked by Richard are used.

I used the brass T-connectors. They're available in a line joiner version too. They require a fair bit of torque to tighten onto the little olive but once fitted they're absolutely air tight - set and forget.

+1 on the brass connectors. I use Wade connectors that have a central spigot that the tube goes over. A brass olive tightens down on it.
Some of mine have been in 10 years plus.
