The Silca Thread-On Schrader Chuck is a direct replacement for the Schrader-valve chuck used on Silca pumps for over 25 years — sourced from the same supplier, built to the same standard. Machined from nickel-plated brass with an o-ring seal, it threads securely onto Schrader valves and connects to your pump hose via a standard barb fitting. If your existing chuck has worn out or you're adding Schrader capability to a pump that only came with a Presta head, this is the correct part. It's also a logical companion purchase if you're fitting a new stainless Presta chuck or CP1 Disc Adapter to an older Silca pump — keeping both valve types covered without replacing the pump itself.
