About Rotary Shaft Seal Manufacturer CinchSeal®

Industrial Sealing Solutions

Self-adjusting rotary shaft seals for industrial screw conveyors, ribbon blenders, paddle mixers, and all types of bulk-handling equipment have made CinchSeal® a leading rotary seal manufacturer for over 25 years.

Using air purge or nitrogen purge, our self-adjusting screw conveyor seals, externally adjustable blender seals, and cartridge seals keep product away from the seal, minimizing product loss and maintenance costs.
