By creating a deflection zone, the Smart Elbow virtually eliminates elbow wear, product degradation, plugging, surging, cross contamination, noise, and turbulence. Its design saves space, time, and unnecessary costs. These elbows can be used in a variety of applications including plastics, grain, pulp & paper, and wastewater treatment. If, during the approved warranty period, there is a problem with your Smart Elbow, the company will replace it with an equivalent or better elbow, one time, free of charge.HammerTek Corp., Landisville, PA 800-505-9665 www.hammertek.com
