NL8211 has layers of steel wire reinforcement designed to handle wet concrete with high head pressures at the critical flex areas on boom trucks. It is also used as a discharge hose on the delivery end of high pressure pumps and drilling equipment. *Service life of material handling hoses may vary depending on the operating conditions, hours of use, and the product being conveyed. Always rotate the hose regularly for even wear and inspect the tube for degradation before use. Concrete hose is typically not repaired as the wall/tube will wear down during service, and therefore the coupling integrity is significantly compromised if re-installing an end.

Construction: Tube: Smooth, black Chemituf rubber. Cover: Wrapped, smooth, black SBR rubber. Reinforcement: Multiple spiral plies of high strength fabric (NL8210) or spiral plies of high tensile steel wire (NL8211).

Typical Fittings: WFT-CS Heat treated swaged ends (HD California flanged ends for concrete pump hose, DO NOT use Grooved or NPT ends for concrete pump service). N95 Galvanized Internal Expansion (1"-1-1/2"). Whipcheck Safety Cables & Nylon Slings (must be properly installed in an extended position). *SPECIAL NOTE: Concrete hose is typically not repaired as the wall/tube will wear down and therefore the coupling integrity is significantly compromised if re-installing an end.

Temperature Range: -35°C (-31°F) to +80°C (176°F)

Detail Comments: Working pressures shown based on this hose being used to transfer concrete, not for water or other fluids. For non-concrete applications the working pressure will vary depending on the safety factor required (as an example for water, certain sizes could be rated to 500-600 psi). *SPECIAL NOTE: Concrete hose is typically not repaired as the wall/tube will wear down and therefore the coupling integrity is significantly compromised if re-installing an end.
