A stainless steel side-lever locking chuck, capable of reaching over 250psi without needing anyone to hold the chuck on the valve. The Hiro is SILCA ’s version of the popular Hiram e chuck that’s been around for decades. And, while both chucks are technically rebuildable, you’ll actually be able to find the replacement parts for the Hiro. It’s a fantastic device that’ll give you the freedom and flexibility to pump up your wheels, disc or not, to high pressures without the assistance of a second person. It comes with a 25 year guarantee, is entirely made in the USA, and can be used with any Schrader-compatible chuck. Show more
