Designed to replace broken or aging fittings, it prevents vacuum and oiling leaks in Mercury, Mercury Hi-Performance, and Mercury Racing outboard engines.
 
This precision-molded fitting plays a critical role in the bleed line system, which recirculates excess fuel and oil back into the cylinders. This process enhances engine efficiency, minimizes waste, and extends engine life by preventing buildup.
 
Our corrosion-resistant hose barb tee fitting is built to withstand harsh marine environments, including saltwater exposure, vibrations, and fuel-oil mixtures. Its precise design ensures a secure, leak-free fit for 1/8-inch bleed lines, maintaining proper engine function.
