O-Ring of the three-point hydraulic lift piston (o-ring 04811-00650, ring 34220-37380) with an internal diameter of 62 mm and a thickness of 5.50 mm for Kubota tractors of the Kubota L2201, Kubota L2250, Kubota L2350 , Kubota L2600, Kubota L2800, Kubota series L3000, Kubota L3301, Kubota L3800 and others.

An O-ring is a type of circular seal and comes in many sizes and diameters. The main task of the O-ring sealant is to seal in places where there is no high pressure, but also places subject to high pressure. The O-ring sealant, under the influence of high pressure, acquires properties similar to those of a liquid (surface tension, plasticity, etc.), which gives very good sealing properties.

A retaining ring is a rigid ring, usually made of plastic, that protects O-ring seals against damage caused by the high pressure and temperature inside the hydraulic system during operation. Back-up-ring is a ring whose main task is to prevent the O-ring from being pressed into the gap between the sealed surfaces and protects the sealant against shape changes that may occur when high pressure and temperature are applied to the seal. If the pressure acts on the O-ring from two directions, we use a resistance ring on both sides of the O-Ring seal.
