How difficult is it to exchange the barbs on the DD Maze 4 GPU block? Has anyone actually done this?

As I understood the block was tapped specifically for the barbs attached. Since you own one, I figure you would know better than I though.
Danger Den is in the process of switching from 9/16-18 threads to G1/4 and which barb your Maze takes is unknown (to me, at least).Captain Helghas said:
These are the new G 1/4 fittings and these are the older (and slowly being phased out) 9/16-18 barbs. Note the difference at the barb end where the tubing slips over. The G1/4 barbs have a very narrow/short lip where the older style has a long, tapered lip.
Once you have the correct threaded barb, swapping them on the block is simply a matter of screwing it in.

IF the block uses HiFlow or PerfectSeal fittings, Teflon Tape is NOT required... both HiFlow and PerfectSeal fittings use an O-Ring seal. You only need to use tape when using either incorrectly threaded fittings, or non o-ring fittings.

Since we're so close together we could combine our order, and share the shipping cost. Then mail in an envelope the barbs to the other person.scott d said:

the barb's thread type is what matters. looks like BSPT instead of NPT. looks like they just changed suppliers for the barbs but thread type/pitch is the same.

p/n 53415k213 - it's 1/2" x 3/8" bspt $4.52/pkg
you'll want to get some O-Rings for them then..HD should have them.

I knew I forgot something
I used silicone to seal the the space between the threads, so maybe thats just as good, since I have had no leaks yet.

my plain teflon tape on my maze4 works fine. never leaked there (though it has leaked when my clamps weren't tightened all the way.
