Don’t forget the end fittings when you purchase an inline gas regulator

Recently I talked to a couple of customers who ordered an inline gas regulator, but didn’t order any end fittings, so when the regulator arrived, they weren’t able to connect it to their gas line.  As a result, I decided to write this post to remind our customers that they may need to purchase end fittings when ordering an inline gas regulator.

Because each of our inline regulators (catalog numbers 21666* or 22452*) has 1/4 inch FNPT (Female National Pipe Thread) ports on each end (input & output), you would need two fittings for each regulator.  Because we sell associated fittings in ten-packs, you will have spare fittings if you order just one of the following catalog numbers:

To connect to 1/4 inch copper tubing, choose 23134 if you prefer Swagelok® fittings or 21842 if you prefer Parker® fittings.

To connect to 1/8 inch copper tubing, choose 23136 if you prefer Swagelok® fittings or 21844 if you prefer Parker® fittings.

(Note:  You may also want to order some PTFE tape if needed.  ResTape PTFE Tape)

 

If you are reading this and realize you actually need a regulator with a CGA fitting (to connect to a tank/cylinder), I have a previous post which discusses these regulators (link below).

Need some help in choosing the correct gas regulator?

*The difference between 21666 and 22452 is the gauge; 21666 is designed for an outlet pressure up to 50psi and 22452 for an outlet pressure up to 100psi.  Maximum inlet pressure is 3000psi for both regulators.  Additional information is below.
