The JConcepts Medium Bore Glue Tip Needles are much needed accessories for any pit bag. It's common to see racers scrambling for the right part in the pits, and glue tips seem to be one of the most sought after items. Typically, one needle will last several weekends or more, however under certain conditions they seem to get lost in the shuffle or cleaned incorrectly, leaving the racer without at a key time. These RM2 needles are plastic tipped so the length can be trimmed for a fresh surface and clogging can be minimized. The thin bore tip is best used with very thin glue (JCO2043T) while the medium bore is best used on the medium viscosity (JCO2043M). Features: Durable, long spout for easy trim or tune Flexible plastic material, less clogging than metal 10 pieces included per package
