RUBBER MATERIAL HANDLING HOSE

G741… GUM RUBBER MATERIAL TRANSFER The extremely abrasion resistant gum rubber tube in G741 allows it to stand up to most non-oily bulk materials such as gravel, sand, and fertilizers, while the built-in static wire dissipates static electricity when properly grounded to couplings. Because natural rubber is quite soft, fitting retention can be difficult and so for pressure applications, double bolt clamps may be required. Temperature Range : -40°C (-40°F) to 70°C (158°F).

G743… RHINO MATERIAL HANDLING Rhino Hose is our heaviest material handling hose and is ideal for handling slurries, gravel, ore, and other abrasive materials where con ditions are severe. The 3 ⁄ 8 " thick, natural rubber tube is not designed for hose inserts and so using an over-the-cover flange fitting system with the corrugated cover provides a full flow coupling that can be easily installed in the field. Temperature Range : -40°C (-40°F) to 70°C (158°F). Working

Use G79 External Flange Couplings for a full flow coupling.

*Note: 10" size measures 9.85" actual I.D. to allow conformance to external coupling size while maintaining 3 ⁄ 8 " tube thickness and 150 psi rating.
