ThreeBond 1206c Equivalent

[doornail385]

I need to pull apart the hydraulic cylinder assembly on my MX5400 and the service manual calls for TB1206C during assembly. I can't seem to find that anywhere. What's a good equivalent?

That's showing it's for 1207B, is that similar enough? I would have expected something like 1206D be closer?

Three Bond does not list 1206 as a current oroduct. The 1200 series are all silicone RTVs of one sort or another. I doubt it much matters ad long as its resistant to hydraulic oil.

That kinda explains why I can find $200 tubes from Japan, but nothing reasonably priced or available in the US. I had a feeling it was discontinued or something like that.

If that's the case, would Permatex Ultra Black be a close enough substitute? I have already have a new tube of that.

Also, thank you. I don't have much grasp on sealents and how to understand the specs I was able to find. Breaking it down as a silicone RTV helped a lot.

Thats a tough question to answer. I would look at the data sheet for the Ultra and see if it matched the application

I'd stay withe a ThreerBond 1207. About $25. The sad partis you use so little and the tube, once opened, like caulk, goes bad in time.
When using, less is more, just a tiny bead as it squishes. Perfect amount barely squeezes out the seams.

I have been using Permatex Ultra Gray for 10 years, as 3Bond is so expensive. The gray dries a little harder and will hold much more pressure; beyond that, they are the same. The gray also blends better with Kubota's gray paint.

I also Use Ultra gray, Ultra blue and, Ultra black all have worked perfectly.

I put aluminium foil over the thread at the top when storing long term and pull electricians tape tightly around it to seal. Alternatively you can wrap the whole tube in aluminium foil, get as much air out as possible and fold the edges tightly a few times. Metal foil is vapour tight, same as the unopened tube that typically has a thin aluminium lid that you have to pierce first.

Metal foil is vapour tight

That is a super useful and obvious thing that I never quite realized. Thanks!
