Presta Valve Core Kit – 4 Cores, Removal Tool & Pump Adapter

Keep replacement valve parts together with the Velo-Tool Presta Valve Core Kit. It combines four spare cores, a compact core-removal tool and a brass pump adapter for compatible removable-core Presta valves.

What’s included

• Four replacement Presta valve cores.
• One valve core removal tool.
• One brass Presta-to-Schrader adapter with an internal sealing ring.

Check your valve system

Not all Presta valves have removable cores. Confirm that your valve permits core replacement and that these cores match the valve manufacturer’s specification before ordering or fitting.

A replacement core will not repair a damaged valve stem, a leaking tube-to-valve joint or every cause of slow air loss. Diagnose the source of a leak before replacing parts.

Use with a suitable pump head

The brass adapter provides a Schrader-style connection on a suitable Presta valve. Check pump-head fit, exposed valve length and available clearance. It does not establish compatibility with every Schrader pump or regulate inflation pressure.

Service with care

Follow your valve manufacturer’s instructions, including releasing pressure before removing a core. Use the tool only when it engages correctly, keep threads and seals clean, and avoid cross-threading or over-tightening.

Refit and inflate according to the valve, tyre and rim manufacturers’ guidance. Check for leaks and correct operation before riding. Replace damaged parts rather than forcing them into service.

For your repair spares

Store unused cores where their threads and seals will stay clean. Pump, complete valve stems, tubes and tyres are not included.
