yeh clippard are good needle valves

i got myself a MNV-4K2.

and it works just fine...

Dave Gomberg's Fabco's are very nice and for the small extra cost, are worth it.
6 for 100$= 16.66 ea vs 11.10 for the clippards.

Shiping is less with Dave but I pay nothing since he's local.

Next step up goes to the Nupro which are 38-39$ before shipping.

Get a few barbed-barbed ends on some to use right at each tank after you steo down, this makes dosing easier.

Works well for me, I didnt get the one with the large knob on it as it might get knocked
