I got a NX bottle off of someone the other day and picked up bottle nut adaptor off ebay and realized nx uses a 2 piece design. I need to get the plastic washer for it anyone one the size and also does NX use something else instead of it since its a 2 piece design (like rubber or something). Thanks in adfance

 

Do you have a picture of the valve? One style uses a teflon washer that rests against the flat face of the threads and the other is a nut & nipple that seals with a pressure fit. If it's just a plastic washer that you need you can go to a welding supply place and pick one up there.

 

this is the set up it uses on the nx bottle



nipple fits into the bottle nut

 

this is what i show on nx's site under instructions
Insert the bottle nipple (3) into bottle nut (4) and securely
tighten on the bottle valve. (See Illustration A.)

So maybe no washer?

No washer needed

 

Correct, no washer. Just crank it down pretty tight and you should be oK!

 

The nipple will seal by compressing into the valve when you tighten the nut..
