Threebond Sealants - Never Ending Frustration!

[Vintage Engine Repairs]

Threebond sealants are great for saw builds, but their caps ALWAYS split on me after a few times of unscrewing and screwing them on, then the sealant dries up in the tube. Out here in Australia a tube is 38 dollars, so I want to save every drop! This time I decided to make my own cap and fine tip nozzle lol.

You’re on to something here. Could be a $$ venture for you if this catches on.

Nice ! At $38 a tube, definitly worth the effort,

I had a tube of yamabond. Got tired of constantly having to clean out the cap. Went back to Motoseal

Nice, I love motoseal for that reason but it’s not good at gap filling. Great for base gasket deletes but I have had more failures than success with clamshells using it.

I guess I’m just lucky. I have done 15–20 clam shells with it and never had any of them fail

Maybe it’s me doing something wrong!

That's a slick-looking cap Tom - I've never had those issues with Threebond type sealants but I've definitely had
those issues with Shoe-Goo and Plumber's Goop which I use to help affix the plastic Stihl model plates on newer
saws when wallow out the tag holes from vibration (usually on the cylinder covers). The Goop products seem to
split the plastic cap every time, probably due to the solvents they contain.

Thanks mate, yeah I think you’re right it’s probably solvents reacting with the plastic!

Slick trick! It is an issue, it surely is.
You could probably have a full time job making and selling these if you wanted.

Haha I’d go broke! Took me nearly 2 hours lol that said for my needs it’s worth it. I can unscrew and reuse it on the next tube

Most of us just like to complain. You created a solution instead. Kudos!

Just while I’m here on the topic, I use to always put grease on the sealer and cap to stop it setting. It’s so darn messy. Randomly I thought of putting some inner tube in the cap and it’s been perfect. No drying up of the sealant and no messy grease to have to deal with each time :

I will try and see if the rubber inner tube trick works for me

Thanks Tom

All good mate

All good mate

What about just putting it the fridge like other RTV sealants to prevent it from setting?

This is easier I guess.
