Global Forum Users: Who Can Identify This Water Jacket?

[Meniscus]

OK, I know there are a lot of product gurus on this forum from around the world. Here is a challenge.

Does anyone know who makes this water-cooling jacket? Are they still available and are they available in longer lengths? Also, are replacement o-rings available? This particular water jacket uses thinner o-rings than I've seen on any others and is also a very tight fit for even Lehners. This particular one in my possession is for a 36mm diameter motor.

I greatly appreciate the help identifying the manufacturer and/or supplier!

Ben,
The O-rings should not be that hard to find. Pull one out from the shell measure the cross-section and look it up on McMaster. Manuel Wenny would likely know where that jacket came from. I believe he has a pair in a cat.

These jackets were originally made for Hopf, most of them with Tenshock sizes.
Hopf closed shop years ago, but the guy that used to fabricate some of the stuff for him had a shop on Ebay. The name was CMT, but is also now extinct...

Thanks guys. It is greatly appreciated. I'll have to measure the o-rings if I can get them out without damaging them. I regularly affix water jackets to motors using various adhesives to avoid water leaks at higher speeds and higher pressure.

As a side note, in my book, the loss of Hopf many years ago is one of the biggest tragedies to this hobby, especially for electrics. Some of those models had some of the best designs on the lower half that are still applicable today. Only minor modifications were required to the top for the increased speeds we see nowadays. The next is Schulze, but MGM has been stepping up their game to help fill that gap. Incidentally, many Hopf hulls and molds still exist today with other manufacturers around the world, so not all is lost.

You are so right...
Some of his hulls are still available here:

I have measured the o-rings. The outside diameter is 0.006" or 1.5mm. The size measures 35.6 to 35.8mm.

Hi

What length are you looking for ?
I should have some fitting for Lehner or Vortex.
If you are interested pm me

Thank you, it is greatly appreciated. I'm going to try the o-rings that Travis has available. The other motors I am running need a custom water jacket that isn't available for purchase. I believe I have those coming as well through a personal friend.
