FUJI Bond...aka Super three bond or what not

Ok, the gray (or grey?) stuff that SUBARU uses to seal up all kinds of odds and ends...aka the cam case to head joint on the EA82...oil pans on the EJ's and all sorts....

 

We call it Fuju bond...its some tough stuff. I found a tube that was cut and spilled, and it was damned near impossible to cut thru or peel up....its still where I found it...stuck on that box and 1/2 dried up in the tube. :lol:

 

Basically i think its a specially formulated silicone sealant made by FUJU Heavy Industies.

 

Anyhow, we reguarly stock the stuff for our techs here...and one tube can easily reseal several tens of engines.

 

How much interest would there be for this?

 

Price would be $25 shipped on a tube (regular retail is $26...shipping UPS cost us around $4~$5 for the small stuff, so you are geting a deal). One tube is listed as 250G/8.8 oz.

 

Its great stuf, I just got myself a tube! :banana: And the EA82 headbolt socket! :banana:

Its a metal to metal gasket for use in yamaha motorcycles, harley makes a similar thing, but everyone at the shop prefers the yamabond over the harley stuff.

 

BTW Will, they want way too much for the valve adjuster and socket.

Oh, must be similar to what Porsche has...some really goooooey brown stuff they use for HG's on the air cooled turbo 6's back in the day.

 

I doubt you could use this for HG, but it is used to seal up areas that there is no gasket....or you could ise it to seal up holes in something or what not.

Gee, on all the Porsches that I have worked on and owned, I never used any type of a sealant on the head gaskets, nor did the factor manuals recommend any. But, there was a special sealant used on the joint between the two case halves. That sealant was a redish brown color, it is made by 3M, I think I still have an old tube (probably not good any more) laying around somewhere.

At the dealership I used to go to, the parts guy said to just use permatex 'Ultra Grey'. It seems to work pretty well, as long as the surfaces are clean and relatively oil-free when you apply it.

 

He knew his EA engines very well. Owned a few, and repaired them himself.

hahaha...ultragray....what a joke. Of all the ultras that Ive used the Copper was the best. After it sets, its go enough to use as an exhuast gasket.

 

As for the borwn junk and Porsche, I'll need to tripple check my sorces before I protest that. :-p

hahaha? really??? Im laughing at the thought of paying 25 bucks for a tube of sealant that isn't any better than UltraGrey. I work in a shop and we use it all day on engines and trannys and it never gives us any trouble.

:confused:

 

Of all the UG I've used, its never done what its said to do, and it easily comes apart. I never said that UG and FB are the same.

Please correct me if I'm wrong....

 

An anaerobic sealant is ideal for metal to metal mating like case halves and cam covers. That's what they use on big diesels too. As I mentioned, Permatex Anaerobic Sealant has worked great for me so far, and it's what we use here at UAA on everything like that. Isn't Ultra Grey a non-anaerobic sealant, ie it sets up when exposed to air, unlike the red stuff that doesn't set up except when it's on a mating surface and oxygen is unavailable?

 

It would seem that an anaerobic sealant would be best because if any extra gets into, say the oil drain passages for the front and rear main bearings on an EA82, it remains soft and gets washed away by the oil, rather than restricting the passage.

I never said they are the same either.

 

I know of at least 3 dealers that don't use Fujibond and instead use Ultragrey.

 

I haven't asked if its a cost thing or if they find it inferior. The fact that they could get Ultragrey at wholesale price and Fuji at dealer cost makes me wonder why the general public should consider it if they don't use it.

 

I will say this. Its alot harder to remove the stuff from block surfaces than the Orange silicone or ultragrey are. I don't think its any indication of quality difference though. I think the usability of a product like this should be measured both in cost, ease of use and ease of cleaning and later use.

Exactly true and I agree but FujiBond is non-anaerobic as well, so I still can't see the justification for the $25 tube. I will be looking into the stuff you use at UAA for sure.
