This 3" Tiger-TR1™ hose is manufactured by Kuriyama of America (Tigerflex® TR1™ Series) — a blended SBR rubber tube with a rigid PVC helix, built for heavy-duty wet or dry material handling. It's engineered for abrasion resistance, making it a strong fit for septic and liquid waste haulers, hydro-excavation crews, and sanitation service trucks moving abrasive slurry or debris.

Step up to 3" for higher-volume abrasive material handling — hydro excavation spoil recovery, slurry handling, and larger sewer/septic vacuum truck boom hose runs. Kuriyama lists this series for sewer truck boom hose, hydro excavation, slurry handling, and rock/gravel/sand vacuuming — all common on portable restroom and septic service routes.

Why operators choose Tiger-TR1: The static-dissipative tube helps prevent static buildup during dry material handling and keeps abrasive material flowing smoothly. The rigid PVC helix stands up to heavy abrasion from grit, ash, and slurry, while the convoluted cover keeps the hose flexible even in sub-zero temperatures.
