The Side-Lever Locking Chuck is classic SILCA quality and manufacturing in every detail.  Made entirely from Carbon tool steel, 100% rebuildable, and utilizing high-tech elastomer gasket design, the 254, which is already available for replacement sale and like all other SILCA gaskets, will remain available for the next 25 years and probably longer.

HIRO is disc wheel compatible and the locking mechanism makes it ideal for high pressure situations.
