This chuck comes from the same vendor who supplied them to SILCA pumps for more than 25 years. It makes a great replacement or addition if you are buying a new Stainless Presta chuck or CP1 Disc Adapter for your older pump. This part is made from nickel-plated brass and uses an o-ring to seal the connection.

- Hose barb fits into all SILCA hoses both old and new
- Threads onto Schrader valves and all SILCA chucks with male Schrader threads (17-4 Presta chuck, HIRO, and CP1 Disc Adapter)
- All metal construction, nickel-plated brass
