40K Flex Lances

40K Flex Lances When your job demands extreme power and flexibility, NLB’s 40,000 psi (2,800 bar) flex lances deliver. Designed for ultra-high-pressure cleaning of pipes and tubes, these lances maneuver easily through bends to clear tough internal deposits with maximum efficiency. Each lance features a smooth inner core that reduces pressure drop, a durable outer cover that stands up to harsh chemicals, and a compact end connection that allows for tight bend radii—ensuring performance in even the most confined spaces. Available in a wide range of diameters and connection types, NLB flex lances come in standard 25′ and 50′ lengths (7.6 m and 15.2 m), with custom options available up to 200′ (61 m) to fit your application.
