The Exalt Universal Compressed Air Tank Fill Nipple Cover has ultra-rugged molded construction and an ergonomic, intelligent design. The cover stands clear of the fill hose when removed, the integrated retaining ring keeps it close and in position for quick attachment. Low-profile, rubber design prevents the fill nipple from digging into your wrist. Internal seal fit keeps dirt and debris out to keep your tank and marker o-rings safe. 

** Will not fit First Strike/Guerilla Air "SHORT" style tank regulators.
