GT3 is a widely used seal manufactured as a set and applied in double-acting cylinders. Composed of three sealing elements: a support ring or base ring in reinforced rubber fabric, a “V” ring or sealing ring which works to exclude extrusion and the spreader ring which has the function of ensuring that there is always uniform pressure. For high pressure, special applications, or the presence of particular aggresive chemical agents, the standard NBR/fabric can be substituted with NBR/FKM material.
