I have my first peterson and the stem has me confused.

System spigot, factory box, i bought it brand new.

The stem is vulcanite according to the gods of paperwork at Peterson, but the odd things is..

1. it sounds and feels like acrylic pipe stem on my teeth and fingernail
2. it has no smell when rubbed
3. it does NOT pass light through from led flashlight from narrow or wide sides.
NEITHER does a DR Grabow I own that was sold in box with "acrylic stem" printed on it.

4. The stem is highly polished and does reflect light very well. But the portion in the tennon, under the silver is a brownish color. Phone sucks..

I've never known of vulcanite that did and I've never seen a System spigot that didn't have a vulcanite stem.
explain why the acrylic stem of the grabow blocked all light through it?

And can you explain why its so plasticy and not well, softer then the grabow stem

You don't say whether you have experience of vulcanite stems with which to compare. The difference in the mouth between vulcanite and acrylic is pretty subtle.

I have a few system spigots and I love them.
I think the vulcanite used must be of excellent quality, IMHO.
Anyhow, I don't think it's acrylic, but to me, a great combined feeling of the "old" vulcanite and modern feeling acrylic.
I'm also a fan of the button dimensions on the system spigot line.

Post 1980s Grabow's use plastic, not acrylic except for their Royalton line. Up until the 80s, they were vulcanite.

Vulcanite is more firm than the soft plastic used by Grabow.

What do you mean blocking light? Vulcanite isn't translucent and only some acrylic is.

I'm pretty sure all System Spigots are still vulcanite. And like @BingBong said, vulcanite is definitely not like biting an eraser. A better comparison (though completely inaccurate still) would be acrylic is like biting glass whereas vulcanite is like biting a really hard piece of wood.

You could put a rubber or silicon pipe bit on it if you want softer.
Like @romaso said, these should give you the feeling that you're looking for:

Nope, you just zeroed in on one source that was incorrect. I don’t know any group of pipe smokes that would have “everyone” saying vulcanite would be like a pension eraser or gasket material.
The whole “passing light” is a new one to me, I’ve not seen any black plastic, acrylic, not vulcanite stems that aren’t 100% opaque.

That’s probably a very nice spigot Peterson you’ve got there, too bad the only pic wasn’t very informative…

Sounds like this is your first vulcanite stem. Congratulations! The brown end of the tenon is a giveaway, assuming it's clean and not tar. Hard rubber, in the case of vulcanite, is harder than car tires, which is probably what you were expecting. They used to make bowling balls out of the same material. It shines up real good. It can also be brittle and break if dropped right.

In another year you'll be complaining about the Vulcanite oxidizing.
Once it starts, you will beg for Acrylic stems. :)
I prefer Vulcanite, but I'm plenty happy with my new Peterson with an Acrylic stem. Keeping Vulcanite looking good CAN be a chore.
