J-B WeldEPOXY Mix NOZL 2PJ

These are for the 25 ml syringe. Just in case anyone else misses that. Entirely my fault thinking they were the smaller ones. Aside from that I just bought a 25 ml syringe. Problem solved.

This mixing tip, with it's small nozzle, made it perfect for my Model Railroad application. :-) !!

Work like it should, better actually.

Description states comes with 4 static mixers, I received a single 2 pack of mixers. Thought it would be two packs of 2.

These nozzles fit the JB Weld twin-syringe epoxy products. Without the nozzle, the twin-syringe dispenses equal amounts of epoxy and hardener that you must mix and then apply to your project. Oftentimes, you would like to be able to be precise in the application, which is difficult with a puddle of mixed epoxy when the clock is ticking. That’s where these mixing nozzles come in. They use what is called a static mixer in the nozzle tube to thoroughly mix the two components. Static mixers are common in industry and work very well to effectively mix the two parts as they flow down the length of the nozzle. The tip of these nozzles narrows nicely for precise control of the application. The epoxy curing clock starts when the two parts enter the nozzle, so as long as you are using it continuously, it will continue to flow as you are pushing it through. Once you stop pushing it through, what remains in the nozzle will harden inside the nozzle. So, when you’re done applying, remove the nozzle and through the nozzle away. Then, reinstall the plug into the twin-syringe and the epoxy parts will keep just like a new, unopened tube. You do lose a little epoxy product when you throw away the nozzle, but that’s the trade off for having a precise nozzle for application. Great product when you need it.

Would recommend purging/wasting the first few mL or so that comes out of the nozzle as it may not be mixed appropriately. All mixing nozzles suffer from this issue. It was kind of hard to find these and I felt they were priced high for what they are. Personally I will stick to the popsicle stick application/mixing method for JB.

They fit the JB tubes correctly.

These work great for filling holes.
