Design Description：

Spo is a low friction piston seal with two-phase action and o-ring as elastic compensation. Suitable for high and low pressure sealing systems. 

Through the radial interference fit and the compression of o-ring, it can ensure a good sealing effect even under low pressure. When the system pressure rises, the o-ring exerts more force through the fluid to make the seal ring close to the sealing face.

Characteristic：

The standard piston seal assembly consists of a rubber element and a PTFE wear ring.

Simple seal installation

Rubber components: high-strength, low-voltage transformer materials

Wear ring: modified PTFE material
