This chuck comes from the same supplier who has been supplying it to Silca pumps for over 25 years. It makes an excellent replacement or addition if you’re buying a new Presta stainless steel chuck or CP1 disc adapter for your old pump. This part is made of nickel-plated brass and uses an O-ring to seal the connection.
Features:
– Grooved fitting fits all SILCA pipes, old and
new
– Screws onto Schrader valves and all
SILCA chucks with male Schrader threads (Presta 17-4 chuck, HIRO and CP1 disc adapter)
– All-metal construction, nickel-plated brass.
