Type 5903 Bulk Material Handling Hose is an abrasion resistant heavy-wall hose designed for the transfer of highly abrasive wet and dry materials. Also known as Green Monster vaccum hose, it is rated for vacuum and positive pressure applications. This hose features a gum rubber non-marking tube made from FDA compliant material. Bulk material handling hose is a durable option for hydro excacation and vacuum trucks requiring a large diameter abrasion resistant hose. Also see elephant trunk discharge hose for gravity drop of dry abrasive materials. Bulk material handling hose can be custom made with built in end couplings, with higher working pressure rating, or in custom large diameter sizes.
The gum rubber lining is ¼” thick through 5” ID, 5/16” thick for 6” ID, and 3/8” thick 8” ID and above. 5” through 12” sizes have a corrugated cover for increased flexibility.
Also available in black cover with non-FDA natural rubber tube, with or without the wire helix (non wire reinforced hose is for discharge only). See PDF link below for details.
