This Schrader chuck has a hose barb on one end and thread for a Schrader valve on the other.
This 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 valve.
