This bleeder bottle has a unique extra nipple on the top which gives you a place to park the tubing. Any brake fluid left in the tubing will drain back into the bottle, making the job much less messy and preventing damage to painted surfaces. The nipple also vents the bottle so you don't have to loosen the cap and risk spilling fluid. A magnet on the side makes it easy to hang the bottle from any steel or cast iron part -- even the brake caliper!
We also offer a Brake Bleeder Bottle with Lanyard and Hose Drainback Fitting, Part No. 3139. The lanyard is handy for hanging the bottle from suspension pieces.
