You got it. When you are looking at service kits, the latest (46201370) will have the poppet (the T shaped piece that seals against the high pressure seat). You have to buy it separately with the earlier kits.
Here's the current kit which is for both DIN and yoke (INT) (from Maintenance spare parts kit for Mares regulator first stages )
The poppet is at top right. This is the current version of the poppet. It was called the ACT valve when they first released it, but they have very confusingly changed the name to Trimaterial 2K18. Trimaterial was the name of the version that immediately preceded this one. I need to write a separate post on that when I have a bit more time.
The only thing I'm not sure will work is the top hat filter. The stage (and the kits) originally came with a simple disc filter. I think this will fit, but don't have first hand knowledge.
No. You want to install the poppet that comes in the current service kit. Most older factory kits and aftermarket kits don't include any poppet. It has to be purchased separately.
Mares has made at least 4 versions of the T-shaped poppet over the years. All of them will work, as will an aftermarket part from Trident and one used in many Aqualung regs. The difference is in how long they are expected to last. Mares states that the current version, which is labeled either "ACT" or "Trimaterial 2K18", is good for 2 full years, while earlier versions required either inspection or replacement annually.
Sorry for the confusion.

Hi lowwall ....
Not to hijack your thread but I have a question about the MR22 series regs serial nnumbers. I have read your articles and called no joy. What gives with the serial number sequence of these? Some have an "E" prefix, some an "EE" prefix. Some with no prefix at all. Is there any correlation between serial numbers and year of manufacture or place of origin?
Any assistance Is appreciated.
Thanks .... JP

The letter prefix indicates the item. Note that the prefix refers to the whole package. For example, according to a tech bulletin from 2012, an Abyss that came with the Navy set has an NV prefix, while an Abyss Octo has an OY. The number part is sequential for each prefix, so you can't tell which of two stages was made first unless they have the same prefix.
Except for the dozen or so prefixes mentioned in tech bulletins, I don't know what any particular prefix means. Nor do I have any idea what range correlates with what year or if the letter prefixes also indicate the factory.
Mares certainly has this info somewhere, but they don't share it with the public. I should note that I'm not a Mares authorized technician (I have taken rsingler's reg tech course) and do not have direct access to their technical documentation. Everything I reference is stuff I've found online.
