I have seen these valves on the bay. Is the statement below true:
Theoben Rapid compatible, Valve and Stem for 12ft/lb or FAC rifles
Beware of cheaper imitation home made valves listed
fitted with an up rated firing pin with two seals which give a lot better seal and more consistent shot
fits all models of rapid and complete with all o rings
It says oxo on some bus adverts but it does not mean the bus sell them.
Some adds on ebay may be true some may be misleading in order to gain a sale.
When it comes to rapid parts I use a handful of people who have stood the test of time producing them to very high standards.
They are the only people I will ever use for my spares or let them work on my rapids.
And those trusted suppliers are?
IMHO if you fit two O rings on the stem all you will do is increase the drag. The first grove on the original Rapid valve stems was I believe to try and absorb some of the air before the O ring.
Good idea in theory but I do a stem with only one groove that has an O ring in it and it dosnt seem to make a difference.

I have always trusted Dr Bob and KevG as I have used them both for parts for many years.
They both have gained vast amounts of knowledge and trust from many rapid owners worldwide over a long time.
There aftersales is exceptional and they will always give trustworthy advise in your hour of need.
Hope this is of use to you fellow member.
Thanks for the info.
Exactly what Dr Bob said!!
The Titanium Valves I turn have slightly tapered profile with
1 O-ring groove....

But my latest prototype..
Short metal valve body.
Sealing face and stem lined with Delrin
So Valve-stem doesn't have an O-ring groove!

hahaha, compatible with all models...firing pin ;D
what it does is help to seal up a knackered valve body
I had problems with my valve sealing. Bought a Dr Bob valve and stem from Ebay, Sorted my issue.
I noticed the twin O-ring listings, but it seemed like everywhere I read it wasn't a great idea.
Double orings on stem only realy cause a problem on a tight fitting valve and stem.then you can get air lock between the stem orings.
