Perun Nozz-X Adjustable Air Nozzle

Nozz-X is a modular, adjustable lenght nozzle system, which allows you
to achieve perfect seal and reliable BB feeding.

Nozz-X nozzle is made of two parts which are sold separately:

1. Universal base.
Two o-rings with different thickness are included with each base, so
that you can choose the one which provides 100% seal and smooth nozzle
movement with most cylinder heads. The base is designed so, that it
cannot make a full revolution once in the gearbox, which allows you to
adjust the nozzle length with closed gearbox.
