This Schrader chuck has a 3/16" hose barb on one end and threads onto Schrader valves on the other.
The cyclist who is looking to rebuild a pump or replace their existing chuck with a thread-on chuck.
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 to 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
The Thread-On Schrader Chuck is ready to use when removed from the package. If you would like to learn more about features, functions and maintenance of the Thread-On Schrader Chuck, please visit the SILCA resource center.
