Left handed thread on regulator

[CoreyD]

I need to convert all of my CO2 regulators to 1/8" NPT on the input and output. I am using smaller tanks that that will be remote from the regulator. My primary regs are all left handed thread on the high side and I cannot find any fittings other than plugs that are LH. My secondary regs are all RH thread on the high side. Is there a reason for the use of LH thread? Is there a fitting that converts 1/4" LH to 1/4" RH? Or can I switch the internal components of the primary and secondary regulators to make what I want?

Never convert a secondary regulator for primary use. The reason for the LH and RH is so that the secondaries cannot be used on high pressure applications. Your best bet would to find a fitting that will convert from LH to RH. Only LH threads I am aware of is bicycle pedals.

If you are using low pressure in your cylinders applicable for secondary regulators, then you may be in luck.

What fitting connects primary regs to the secondary regs in the inline assemblies, it should be 1/4" RH X 1/4" LH. Is there a part number available? The inlet pressure will be around 1800psi.

Thanks,

Primary regulators are never connected in-line with secondaries. With 1800 PSI, you will require a primary regulator to reduce the pressure down for use at a secondary. Whatever cylinder you are utilizing, you should possibly use a primary regulator built for this vessel's valve system which is specified for this 1800 PSIG.

The cylinder is a paintball tank and the regulators for these tanks are too small to handle the volume of co2 for a keg. What I did was take a LH pipe plug and drilled and tapped it to 1/8" NPT to act as a reducer.
