Shaft universal plug seal type RS19
Function: separate piston rod seal, the sealing lip has various designs, which can achieve the best sealing effect, reduce friction, and ensure the service life of the seal. Leakage will not occur. Due to the excellent performance of PTFE material, stick-slip movement will not occur at different speeds of the rod, even when the speed is very slow. Due to the viscosity of the medium, no leakage will occur at all. The materials that our company can make include various rubber materials (NBR, FKM, FFKM, SIL, EPDM, HNBR, CI, etc.), various polyurethane materials (oil resistance, hydrolysis resistance, high temperature resistance, food grade, ultra-wear resistance, etc.), various engineering plastics (PTFE, PTFE composite, ultra-high molecular polyethylene, PA, POM, phenolic resin, etc.) and metal materials.

Parameters

The internal open type is suitable for internal positive pressure conditions. The C-ring is a typical self-sealing structure. When the medium pressure enters the C-ring in the working state, the pressure self-tightening effect is generated on the C-ring from the inside to the outside, that is, the greater the system pressure, the better the sealing effect. Due to the principle of opening and self-sealing, it is only necessary to overcome the elasticity of the sealing ring itself during installation, so a very ideal sealing effect can be obtained without using a large pre-tightening force. Our company adopts INCONEL 718 alloy to manufacture.

Advantages of universal plug seals for shafts：

● Can adapt to most fluids and chemical products;

● Small friction coefficient, wear-resistant, stable size;

● Do not crawl while controlling;

● Strong corrosion resistance and good dimensional stability;

● Can withstand rapid temperature changes in the environment;

● Liquids that do not contaminate food, medicines and liquid medicines;

● Can be detoxified and stored indefinitely.

Install：Generally, it is recommended to install in open grooves, some of which can be installed in semi-open grooves or closed grooves (professional installation tools are required)
