Product Introduction

TECHNICAL DRAWING

B3 piston rod seal is a lip seal with two sealing lips and a tight fit at the outer diameter. Dry friction and wear are greatly prevented by the extra lubricant between the two lips. B3 piston rod seal is a single lip seal, this type of seal can be used in ordinary rubber or fabric reinforced rubber physical properties are not up to the requirements of the various occasions.

Installation
This kind of seal should have an axial gap. In order to avoid damage to the sealing lip, do not pull the seal on the sharp edge when installing. These seals usually fit in closed grooves and require special installation tools where access is restricted. Upon request, the company will provide the design of such tools.

Material
polyurethane based material with A Shore hardness of about 93. Compared with other polyurethane materials on the market at present, its main advantages are improved heat resistance, enhanced hydrolysis resistance and small compression deformation.
