Dual regs - are they beneficial?

[Fatbob 59]

Looking for some help from anyone who machines up parts..

The reg has an output thread of G1/2-14 but the block is m18x1.5, I need an adapter that can also actuate the pin valve on the reg, any takers?

How much thread length do you have in the block , is the block recessed for an O ring like a bottle neck or does it have an O ring that seals in a bore ? I always remove the valve pin and seal the reg to adapter with an O ring at the back of the thread , much easier than a valve actuator , if I need to remove the bottle I loosen one of the burst discs to dump the air

I’ve marked up a few photos, as I’m crap at sketches..


it has an oring on the small valve face (pic3), which seals into recess (pic 2). The oring in the 1st pic is to ensure alignment of the gauge & foster fitting..

The threads on the valve are M18x1.5 and 13.5mm in length. What I‘m looking for is an adapter that replicates the male end of the existing bottle valve and has a female thread that accepts G1/2 thread for a paintball regulator.

Any ideas?

Well I have the answer…. Dual regs made a very consistent rifle far less consistent.

Used the same tin of pellets and had the chrono results witnessed. 5 shots with original bottle and ‘onboard’ reg gave an amazing 1fps spread, swapped out the bottle for the one fitted with the paintball reg @130bar and did not touch the ‘onboard’ reg which gave a spread of 35fps.

an epic fail

Hi, I'm sorry but I have an old fashioned approach to machining, a 14mm diameter thread for me would need 14mm of thread, and so on. I do know of people who measure nuts and consider that as sufficient, but it makes no sense on softer metal like brass or alloy. Pressure also matters if on 300 bar more thread is important so the adaptor is not in fact a bomb!! Stay safe, and watch out from where you take your advise. Blessings. C S W

Dual regulators should be by far the best! 300bar to 90 bar regulator 1, 90 bar to your set pressure regulator 2.
Perhaps you have a stuck or faulty regulator? I use an HW100k with single regulator it has worked well but been rebuilt many times!
One only needs a leaking 'O' ring and a regulator in not a regulator. My rifle has two vent ports on each end of the regulator piston, so if the piston is out of normal position due to a seal defect, it dumps the air. Frustrating but safe! Best of luck. C S W

In theory, practice proved otherwise.

No, both working perfectly in solo.

Yep, same for them all
