MacDev tank regulator?

[Siress]

I've had this in my parts box for so long I've nearly forgotten what it is...

Anyone have some info they can provide on how to rebuild this thing, what/where to acquire parts, specifications, etc?

Thanks

MacDev may still have some spares. Here are the 2 manuals I have:

Yours looks like an 02 which is supposedly quite different internally from the 03/04, but those manuals may help. (I've never seen an 02. Have 2 or 3 of the 03/04 here though.) Otherwise try emailing MacDev Australia. They should still at least have a manual for the old stuff.

Edit: Not sure why the link text is "Youtube Video". Each of those links points to a PDF.

Thanks for the info! How does it stack up against other adjustable tank regulators available these days?

Those regs are okay on the low end, like 0-400. But after that the on/off lever gets really tough to move. The higher you go, the harder it gets.

What rawbutter said.

In addition, the 03/04 can use the "008 mod", dunno if the 02 can. The mod, (a kit from MacDev,) allows the use of standard urethane 008 o-rings for the reg seat, so you should be able to rebuild it forever. I love adjustable tank regs, but there are hard/impossible to get parts for some of them. Haven't found replacement seats for Air America Apocalypse/Armageddon, or pins for Centerflag Dynaflow. The latter is my favorite one for light weight. It's tiny, and has a venting on-off.

I have a MacDev on an Etek and a Cocker, (for low pressure,) Dynaflow on an X-valve Mag and waiting to go on another Cocker, and an Apocalypse on a classic Mag.

Good tips, Delta5! Thank you.

That's a shame.
