Not entirely boaty.

I want to secure a press-fit brass tube into an aluminium housing on a carburettor.

Does anyone have experience to share of the relative merits of Loctite 638 versus something like Gorilla super glue? Any other recommendations?

Many thanks
 
When the gear on the motor came loose on my Simrad tillerpilot I found a service report that recommended using Loctite 638 instead of the original Loctite 270. I have yet to test the longevity of the repair but if it is good enough to transmit a constantly reversing motor torque it should be more than adequate on a carburettor.

Compare the technical data for both then make your decision, making sure your choice is resistant to gasoline / petrol

I would NOT use gorilla glue. Its an expanding Polyurathane and if you get to much in there you could have it expand and block bits you do not want it to .
When set it is very difficult to remove so could be a PITA.

Use a liquid loctite much better solution.

How about Hafix glue the guy used to demonstrate at the boat show. He stuck to big metal nuts together and then passed them to me "get those apart". I couldn't. It's like an industrial strength super glue in a hard container with a nozzle. By banging it down when you finish the nozzle is kept clear. Store in the fridge - lasts years. Great stuff.
 
Many thanks to all for your replies, much appreciated.

I was going to post "Loctite 638 it is" but then read the JB Weld suggestions. I'd not thought about that although I do have some on my boat (not that that's helpful to me as it's in Scotland :()
 
If it's anywhere near press fit, you won't get any epoxy in the joint?
The loctite product looks ideal.

Depending on exactly what the parts are, you could also distort or knurl the tube slightly to make a sliding fit into a press fit?
Even roll a slight thread on it?
Or is the 'glue' to seal it?

Since the superglue is released by acetone, its resistance to petrol sounds suspect.

+1 for loctite, it’s what it’s designed to do, anaerobic to set so will set in close fit

There's about a million different 'Loctite' products, including superglue very similar if not identical to the Gorilla branded superglue.
Likewise Gorilla brand offers a whole range of glues.
Same as Sellotape or Scotchtape usually mean a certain thing, but both brands sell a variety of tapes from duct tape to masking tape and all that.

The Original Gorilla glue is an expanding polyurethane but the OP was considering Gorilla Superglue which is a cyanoacrylate adhesive

Read the link to the tech data sheet which I posted in #3
 
Fully understand that, didn’t realise that I had to actually do a product selection for the OP when one had been suggested early on
