The Silca Disc Wheel Adapter solves the longstanding problem of connecting a standard pump head to a disc wheel valve — cleanly and reliably. Machined from 6061-T6 aluminum in the USA, it uses Silca's 252 Elastomeric internal gasket, a material borrowed from industries that demand airtight seals under extreme conditions. That gasket is rated to more than five times the service life of standard carbon-filled rubber or Buna-N compounds. The compression head design lets you tighten the gasket fit simply by turning the cap, improving seal engagement by nearly 200%. In testing against competing adapters, this disc wheel adapter achieved a blow-off pressure of 393 psi — more than three times the nearest rival. Whether you're racing on a full disc or topping up before a time trial, it holds.
