This GMP Tools adapter converts a 4-lug air hose fitting to a 2-lug connection, Vendor Part #89341 (Millennium Part #618259). It is used with GMP fiber optic cable blowing machines and air compressors to match hose and fitting configurations that would otherwise be incompatible, keeping cable placing crews from having to source or fabricate custom fittings in the field. A spec sheet is available on this page for technicians confirming thread and lug specifications before ordering. Millennium stocks this adapter to help fiber and broadband contractors keep cable blowing equipment connected and operational on active job sites.
