The clearance between the piston and the hole determines the amount of dampening. It is usually furnished with multiple pistons or a cylinder with multiple holes. The amount of snubbing can be changed by changing pistons or holes. Piston-type snubbers tend to be self cleaning because of the action of the piston.
