Overview
What makes the SILCA Aluminum Disc Chuck seal where others leak?
The SILCA Aluminum Disc Chuck is an ultra-compact disc chuck adapter designed to be a simple and efficient solution to the typical leaking disc chuck experience. The 252 gasket, borrowed from industries that demand air-tight seals in the harshest environments, tests to a life expectancy more than five times longer than the carbon-filled rubber or Buna-N materials. A compression head design lets you tighten the gasket fit by nearly 200% with a simple twist of the cap, and in testing with a major disc wheel manufacturer the SILCA Disc Adapter posted a blow-off pressure of 393psi, more than three times higher than any competing design.
It is CNC machined from 6061 aluminum alloy with knurled gripping surfaces and the unique bright red gasket. Rated over 300 psi, Presta valve compatible, with an easily replaceable gasket, it threads into any Schrader pump head. It is a natural fit for track cyclists, triathletes, and time trial riders on disc wheels. Backed by the SILCA Lifetime Warranty covering manufacturing defects for the lifetime of the user, with 7-year coverage on hard parts.
