How can I install a quick disconnect into my HPA line?

[harrypoyntz]

I recently bought this used Mancraft SDIK VSR and it came with this white connector looking thing.

What would I have to buy in order to have a QD line attatched to it? What parts/tools. I assume I'd also need a high pressure capable line...

That is a push fit female to female like this:

(Measure the size and/or look for markings in the hose  - in the links below for simplicity I assume that your macro line is 1/4”)

To remove it just simply push the end inwards, tension on the hose line  is reduced and you pull out the hose line while maintaining inward pressure on the fitting 

Check that all the lines still have a clean flat cut.  If you need to cut any lines then don’t attempt to do so with a knife or razor blade, it will never be clean enough for a reliable push fit.  You would need a macro line cutter:

Choose your quick disconnect fittings, eg female with an auto check valve so that it seals the airsource avoiding air loss

To fit these you would need 1/8” NPT to push to fit, such as 

(assuming 1/8” push fit)

Assuming the macro line end cuts are good, then you could get away with swapping the existing female to female push fit with a replacement set of fittings and no more than some PTFE tape (unless the new fittings come pre-primed with PTFE

If they need cutting then the required tool is a macro line cutter 

………

But depending on the point in your line you end up with a dangly fitting, which isn’t elegant or ideal.

Trace back to the gun and find where that fits.  Ideally find a ‘solid’ point that you can fix your male quick disconnect.

You then need the appropriate tools for any modification there 

…….

For hose lines you need an appropriately specified line for the relevant air pressures.

Macro line is good for hundreds of PSI, but it can be good practice to go back one step along regulators - ensure the line can cope with the next highest stage before it’s current regulator 

Note that most links I have provided are with Palmers in the US

You don’t have to buy from there, but do ensure that you buy components designed for the air pressures involved

Thank you very much @Tommikka

Couldn't have asked for a better guide, I'll report back when it is complete ? ?
