Installation Notes
The integral seal's design and metal backbone gives the seal rigidity to maintain its shape. Designed for extended life by establishing optimum squeeze on the seal element. The metal inserts around the screw holes control the amount of squeeze on the rubber, preventing overtightening of the seal. DO NOT CRUSH METAL INSERT.
