Compatible with all of our Presta Chucks, you can use the hose barb to put this into any 3/16" hose and add thread onto a Schrader valve or connect a Presta chuck that has Schrader threads like SILCA 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.
