A hand pump, as powerful as a compressor? Gas cylinders from iSi Components make the impossible possible: Already in the 1980’s a gas cylinder was used, for the first time, as part of a motorcycle repair kit in conjunction with a simple piercing device. The idea quickly found it’s way into the bicycle market, where a thriving niche market was created. Simple piercing devices became innovative inflators and hybrid pumps. With a constantly growing customizable offering we can produce gas cylinders with individual design. But one thing has not changed: as a pioneer in this field, iSi Components supplies leading manufacturers with gas cylinders, which are produced to the same exact standards as those that reliably inflate emergency life vests, and thus ensure the necessary survival buoyancy.
