Koolance QD3 Quick Disconnect question

[Marquez93]

I am planning on using XSPC HighFlex Hose 7/16" - 5/8" tubing for my loop and I wanted to use the Koolance QD3 Quick Disconnect for my drain. However I don't seem to be able to see any Koolance QD3 fittings in 7/16" - 5/8". I'd have thought it would be one of the most common sizes. The closest I can see are the Koolance QD3 Female 3/8 - 5/8 and the Koolance QD3 Male 3/8 - 5/8 fittings. Will they work without leaks with the 7/16 - 5/8 tubing or what fittings do I need to make them fit correctly?

You'll need the 1/2 barb versions for 7/16 tubing

Are these the correct ones? Male & Female.

They may but I'm not sure how well the OD's would match, they are both 5/8 OD but it may change with the 7/16-5/8 tubing having to stretch around the compression barb. So I couldn't recommend those as I've never used them...

I have how ever used (and am currently using) a couple of sets like this with another 2 sets still to fit:

YOUR BASKET
1 x Koolance QD3 Female Quick Disconnect No-Spill Coupling, Barb for ID 13mm (1/2in) £11.99
1 x Koolance QD3 Male Quick Disconnect No-Spill Coupling, Barb for ID 13mm (1/2in) £10.99
Total : £25.26 (includes shipping : £1.90).



This is 7/16-5/8 over the 1/2 barb version above, using a 5/8 OD hose clip just to be safe though I have used them without before too.

Thanks for the help. I'll add those to my order. It's a pity they don't come in black though.

Koolance do make the black versions

They do have loads of black fittings but the ones I require seem to only be available in silver.

Yeah they're a bit funny with certain fittings. They also don't make angled 1/2" 3/4" fittings.
