Barbed brass air nipple!

[mitch1983]

HI GUYS

I'm am installing a fixed air system to the ceiling of my fish room. Made from 20mm conduit and i need some brass nipples to screw into it so i can attach the airline, need about fifteen! Does anyone know where i can buy them???

Thanks, Mitch.

I know you can get threaded plastic nipples from any irrigation place. I have used them in my room

Can you screw or glue them into conduit???? If so i think i will use plastic!

[Josh]

I drilled and tapped the conduit then screwed in the barb. I also put a bit of silcone onto the thread to ensure it sealed

You probably dont need to tap a thread into the conduit.

I'm not quite sure how "professional" you wish to make this because it sounded as though you want to mix plastic-type conduit (my guess here) with brass air/gas attachments.

Are the items in this catalogue what you want (see pages 13-17) or are you after a less costly solution?

Cheers

Mitch,

I use these, drilled into PVC, works well, no rusting. I use pillers to remove from gang valve.

The only place I could get brass nipples that small was a model shop that sells nitro cars.

They use for fuel line connections, I used mine with nuts for diy co2 setup and it works great.
