Cat® Grommet Plates are made from high quality steel intended for the environment of our equipment and used to protect hydraulic hoses from contact with metal and isolate those components from damage vibration, rubbing against the surrounding structure (vibration, shock, noise). Grommets feature a U-shaped plate that flare out on both sides of the material to hold the hose in place.Application:Cat® Grommet Plates are specially designed to hold the hose that come from the hydraulic valve to the grapple cylinder in Cat® equipment.
