5 different advantages of rubber star seals compared with O-rings!

Rubber star sealing ring-referred to as rubber star ring, also known as rubber X-ring.

The rubber star ring is a sealing element that can seal in two directions.

Compared with rubber O-rings, rubber star sealing rings have the following advantages:

It consists of four sealing lips with several cross-sectional shapes, which are distorted in the pipe groove so that they will not roll in the pipe groove during repeated movements.

Low friction because it requires less pre-compression than a Type 0 seal. Less compression means less friction and damage, and then longer service life.

The sealing effect is very good, because there is a good pressure distribution on the star ring cross-section, and then a particularly good sealing effect can be obtained.

A lubrication cavity is created between the sealing lips to improve startup conditions.

Different from the 0-type sealing ring, it analyzes the burr between the two sealing lips and avoids the position of the lips.
