SRAM Bleed Syringe O-ring Kit

You likely need a refresh if you notice fluid leaking around the plunger or coupling during a bleed, or if the syringe struggles to hold a vacuum when you pull back on the plunger. If your syringe feels 'loose' or isn't pulling air bubbles out effectively, replacing the seals is the first step to restoring performance.

This kit is specifically designed for the SRAM Pro Bleed Syringe. It includes the specific O-rings required for the Pro model's fittings, couplings, and Bleeding Edge tool interfaces, so it may not fit standard or generic syringes correctly.

The kit is quite comprehensive, providing 10 of each type of O-ring: fitting O-rings, coupling O-rings, and Bleeding Edge O-rings. This gives you enough spares to maintain your tools for several seasons or to service multiple syringes in a shop environment.

You generally don't need specialized tools, but a small pick or a very thin flathead screwdriver is helpful for carefully removing the old, worn O-rings without scratching the syringe body. Take care when seating the new rings to ensure they aren't twisted or pinched, which could compromise the seal.
