The Lonex Cylinder Head is another addition to Lonex’s lineup of high quality parts. Constructed out of aluminum, not only is the cylinder head lightweight, the durability is by far extraordinary. The cylinder head has a thick rubber padding for shock impact protection from the piston head. On the outer portion there are two o-rings, instead of the traditional one o-ring, for a much better air seal against the cylinder wall. With less air leaks, better air compression is achieved therefore leading to better velocity output.
