Threading Adapter for QD4 Threaded

Postby Nano » Fri May 31, 2013 7:48 pm


Well, i want to know if this ... 3-8-female is the correct adapter for this ... aded-g-3-8 or is this ... 1-4-female.

Building new watercooling system with 1/2 ID 3/4 OD, Waterblock (CPU, GPU, RAM, 2x Radiators) all with quick disconnects.

Thanks for your time.

I'd recommend just going with QD3 fittings for 1/2 x 3/4 tubing since they're the intended size for computer cooling. Flow restriction between QD3 and QD4 for most systems isn't significant (particularly one with components based on G 1/4 threads), but QD4 is a lot larger and threaded for G 3/8 BSPP. If you'd still like to use QD4, you will need ADT-G4MG8F to adapt them for a G 1/4 BSPP female socket.
