These are 0.015" lined, medium duty interlocked metal hoses with a smooth internal metal bore specifically designed for the transfer of a wide variety of dry bulk or hot, abrasive materials (such as grain, pellets, ash, powder, fertilizers, and razor sharp objects that ruin rubber/urethane hoses). Unlike rubber material handling hoses which are typically only suitable up to +82°C (180°F), certain styles of lined interlocked metal hose are suitable up to +985°C (1800°F). Our "non-packed" all galvanized metal hose (NL3660) is designed for use up to +232°C (450°F) and the standard "cotton packed" all stainless steel (NL3670) is suitable up to +150°C (300°F). Other packing materials for higher temperatures are available. The "packing" provides for added sealing capabilities throughout the length of the hose and reduces pressure loss or withstand greater vacuum (ratings vary, max 15 psi to 15 in/hg of vacuum as an example). This hose is "directional" meaning that the flow is only designed to go in one direction as indicated on the hose - so it is important to determine what is the outlet end and inlet end configuration. Standard lengths are 25' and both the NL3660 and NL3670 are available in sizes 1-1/2" to 16".

Construction: Tube/Liner: Stainless steel with a cotton packing. Cover/Armour: Stainless steel.

Typical Fittings: Special, permanently affixed external fittings (solid male NPT, camlocks, and 150 lb flanges are standard).

Temperature Range: -51°C (-60°F) to +150°C (302°F); others for higher temperatures are available.

Detail Comments: Service life of material handling hoses may vary depending on the operating conditions and the product being conveyed. Always rotate the hose regularly for even wear and inspect the tube for degradation before use. This hose is "directional" meaning that the flow is only designed to go in one direction as indicated on the hose.

Warning: Pack safely to prevent transit damage.HOSE FLOW DIRECTIONAL!
