thanks very much jokester should have released that all cpu blocks might have a standed size

also dont suppose you can tell me please if the swiftech microres comes with any barbs at all and the mounting brackets and what nots i no that you get them in the swiftech kits but not sure if you do buying items seperate thanks for the help

Sorry got no idea.

Yes, the Microres comes with plastic barbs and plastic clamps and should come with the L plate mounting hardware.

The old versions didn't used to have the L plate, but all the ones out in retail (new units) should.

uumm plastic barbs so it might be worth it getting some metal ones then i take it the thread size on the res is the same ie G1/4

Here's the pic from swiftechs website

I'm not sure if 1/4 NPSM is the same as G1/4 or 1/4 BSPP, which is usually what other items have

G and BSPP threads are the same, not sure on NPSM though.

steveo · 3 Feb 2008 at 14:42

the 4 letters at the end of the threads is the depth of the thread is that correct :confused:

From swiftechs website http://www.swiftnets.com/products/mcw30.asp

Fittings compatibility note:

G ¼, or BSPP, fittings will fit, but may not seal; each must be checked prior to assuming that it will not leak just because they fit together.

Both NPSM and G ¼ (BSPP) are parallel thread and nominally the same size, the principal difference being 18 threads per inch for NPSM and 19 threads per inch for G ¼ (BSPP). Since most male end G ¼ fittings have a short thread length they can generally be engaged in the NPSM threads without difficulty.

The joint seal is effected with an o-ring which for the NPSM barb is in a groove on the waterblock top and compressed by the flange nut barb.
G ¼ fittings have the o-ring captured in a groove under the fitting nut.

G ¼ fittings will seal so long as there is a straight portion under the nut flats sufficient to bring the G ¼ fitting’s o-ring into contact with the bottom of the o-ring groove, a depth of 0.080”.

Going by this you should by a barb with a short thread, 0.08" is only 2.3mm
