do these fit the JB weld 25ml epoxy tubes?

I don't know about JB Weld. I bought this for 3M Scotch-Weld 08966 Epoxy Adhesive DP420 50mL, DP420, Black

Will they fit adhesive technology JF-311 cartridges?

Tried to look on the site only cartridges I saw were larger than the 25/50ml cartridge these are used for. I would doupt it.

Does this fit 2:1 ratio?

Yes! Good For 1:1 and 2:1 ratio formulas

Where does one purchase the 'needle' tip shown in the sales photo?

Those nozzles with the large round base are available on Amazon ... but they do NOT fit the dual tube Hysol adhesive cartridge. That cartridge requires the end with the flat sides so it will fit onto the outlet and twist-lock into place.

Works Great with JB Weld Epoxy

Works great with JB Weld epoxies that are designed to use the mixing attachment. The shorter length blends well and means you use less for smaller projects.

Perfect Fit

I have used Scotch Weld 420 for a few years & these are perfect tips for the tube & application "gun". They do not slip off & allow me to place anywhere from a single drop to a steady beadline.

Works better than expensive nozzles

Fits on the jbweld and uses less epoxy to mix so there's less waste. I hope these are still around when I run out.

Excellent item! Works with 3M 460 very well

The most important point regarding my review of this item: I'm placing my 4th order. Last one was December 23 and it's Jan. 25. If they didn't work I wouldn't be buying them.

Great value! Work with and work better than commercial products.

These are fantastic! They fit perfectly on JB-Weld products. Best part... they are right-priced IMO. If you use the 1-min epoxy and they clog before you are done... no big deal, right? Just use another one.. Love these! I just ordered more.
