The NL8211 (NL8216 Conti brand) has a 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. Listed below, we also offer part numbers for popular assemblies (suffix is -HD for heavy duty flanges both ends, -H1 for heavy duty flange on one end only, and -VG for Victaulic grooved both ends).

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 (-30°F) to +80°C (180°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).

Warning: Critical Application-Follow Coupling/Maintenance Procedures
