5513 Crowns - AKA Triplock Crowns

 
 By: Bill : March 28th, 2010-08:43

This is a repost of mine that may help

This question has me stumped as I thought the "Triplock" always had an O-ring on the exposed part of the stem where this Triplock as the gasket on the inside.  Again I may be simply wrong in my reading of the Triplock diagram below but I don't see the O-ring in the doc.

 

Thanks

Now we've got 2 threads going!

This is exactly what the one I've been offered looks like, thick but no O ring!

Thanks again Bill,

Peter

Sorry about the double thread on the Triplock.  Hopefully you will get twice the response.  But I think you may already have what you need.

Only joking Bill!

Thank you for the insight. Invaluable advice and pics. The one I've been offered looks identical to the one you've shown.

...in the early 1970's did not have the external o-ring.

When were the crowns introduced?

Is it possible to say what year the triplock replaced the twinlock?

And when the 7030 triplock with external O-ring replaced the 7020 without?

Thanks for any additional information.

Andrew

Here we go...

1971: triplock without external o-ring

Need advice on O ring

 
 By: Democritus : April 1st, 2010-16:58


The O ring on my 16800 sort of tore at one part and I had it replaced at RSC (they replace the crown with the ring).  However, I noticed again that there is a small tear on the new O-ring. Should I be concerned and get ti fixed again or just leave it.  And I do not bring this baby swimming.

Thanks
