german slider M or A coupler questions

[bdavanza]

Hello
I bought a "warsteiner" handled coupler made by micromatic and I figured it's an A coupler. Looking at the website, it has the sight glass section on the co2 side, which makes me think it's an "M", but Warsteiner is listed as an "A".
What I'd like to know is which coupler is it, and also I was looking for an exploded diagram to show what parts in what order go into the sight glass co2 side. There were 2 check valves, which seems odd, and when I thread the steel part onto the end of the coupler, it does not cinch down on those check valves very well. The A coupler has a diagram but the M does not.
Any help appreciated.

I'd go with the info from the Micro Matic site. They have been a major player in the coupler business for a long time and I've never purchased the wrong coupler when I've gone by their listing.

Just completed an 80 faucet system in Richmond, VA. The Capital Ale House is the major beer location in this region. 80 brands from around the world and all of their couplers are Micro Matic and all matched perfectly.

Thanks for the reply but what I'm looking for is not on the micromatic website. There is an exploded parts diagram for the "A" but not the "M" and they describe the M as being very similar to the A but do not offer much information about the differences in the probes themselves. The coupler I have appears to be a custom one made for warsteiner and not a standard off the shelf item.

Maybe I'm misunderstanding the question, but the main difference between the 2 couplers is the size and shape of the probe that actually taps the keg.

The M style appears to be about 1/2" rounded end probe, while the A style is about the size of a nickle and flat.

The probe shape and size must match the keg to safely tap it.

If this is not the question, sorry. Come to think of it, I've got several old couplers in the shop. I'll check to see if I have one. Then we can see what's up.

I bought a keg of Spaten Lager, and the coupler fit and does not leak. So it is an "A", german slider, but with a body like the "M" having the odd sight glass co2 double check valve.
Hoorah. With a keg of Anchor Porter and Coors original, with the Spaten, now I'm ready for the beer dispensing.
Thanks
