Do I get the wrong fill hose ?

[tommyt53]

My new Coltri MCH-6 arrived today and I can’t figure out how this fill hose attaches to my tank. Is it the wrong one and if so which one do I need to remove the fill hose on the tank and screw on the one from the compressor when I want to fill. When I placed the order I asked for the DIN300 hose.

Yes you got the wrong fitting-that's a scuba tank yoke. I don't have a compressor myself so I let the dive shop folks figure it out when I get my CF tank filled. I'm sure someone who knows what you need will chime in-if not, get in touch with these folks-https://experthpa.com/cart/cart.php

DIN300 is the fill adapter you need, so you asked for the correct type. They just sent you the incorrect part. As JohmL57 already stated, that is a scuba yoke.

This is the end they should have sent you based on your DIN300 request: https://www.nuvair.com/1-4-fnpt-300-bar-din-filler-bleed-block.html

Thanks for the replies. Nuvair sent the wrong hose and are sending the DIN300 out pronto with a return label for the scuba hose. Just a minor PINTA.

For reference purposes, in case others need it-

this is the valve-

this connects the valve to the fill whip

Your saying that the DIN200-300 is the one and others have said it’s the DIN300. I ordered the DIN300...what’s the difference because Nuvair carries both.

The DIN200 valve and connector are shorter in the threads then DIN300.

DIN200 valve is 15.5mm~.61" deep.

The DIN300 valve is 22.5mm~.881"deep

That means you can connect a DIN300 breathing system to a DIN200 bottle and all is good (it can handle 50%more pressure).

But the DIN200 breathing system with the to short connector cant reach the bottom of a DIN300 valve and wont function and can't be damaged by over pressure.



So you're good with the DIN300 and can fill all types of DIN bottles.

After speaking with Nuvair you are correct with your part number...thanks

Glad to be of help. The people at Nuvair know what they are doing and I trust them. I hope you get your compressor up and running soon!.

I prefer the twist bleed valve, however, the push button valve never leaks when you forget to tighten it.

I tend to agree with you. The twist bleed is reliable. It does seem that there are many changes going on in the valves, though. The DIN 200-300 and DIN 300 valves have all changed to push valve type. I only found out when I ordered a new DIN 200-300 valve this past summer.
