      When a mommy valve & daddy valve love each other very much…

      Yes, you should replace the tube…….

      Yeah, that will wait for the most inconvenient time, and then pop. Get a new one.

      Is your valve stem bulging? Or is your bike just happy to see you…..🫦☺️

      I have the slime tubes as well. When the lbs installed them the manager said that they prefer to use the Ball brand tubes because they have a threaded metal valve stem with a nut. 

      He said that they don’t sell the Slime brand tubes anymore because they kept failing at the valve stem. 

      I suspect that this is what he meant.

      That tube should be replaced at some point. 

      If you want to try to do a ghetto fabulous temporary repair on the tube you can do it a couple of different ways. 

      1. Heat shrink tubing. Deflate the tube until the valve steam shrinks back down to normal size. Slide a thin piece of tight fitting Heat shrink tubing over the valve and gently shrink it with hot air. Allow everything to cool and re-inflate the tube. This repair *should* last the lifetime of the tube. 

      2. You could also probably use a bit of stretched drinking straw tubing if you can find one that will normally just fit over the valve stem. Stretch it gently just like you would the heat shrink tubing. Insert some rounded (non-folding) needle nose pliers into the straw / shrink tubing and then open the pliers to stretch the tube. It takes a considerable amount of force to cold stretch plastic tubing like that. It will be more than capable of holding bicycle tube pressures. 

      3. Cloth hockey tape. It’s reinforced with material that does not stretch. Deflate the tube and when the valve stem returns to normal size, apply a few tight wraps to the valve stem. Re-inflate the tube and you should be good to go. 

      ***

      Be careful not to cover the metal threads what ever way you go. 

      You can do this trick with lots of stretch resistant materials but keep in mind that it’s a temporary fix. 

      That tube should still be replaced. 

      If you contact the manufacturer they may send you a replacement tube. 

      Good luck!
