food grade o-rings

food grade o-rings

fluorine rubber ring high wear resistance, sealing surface wear with automatic elastic compensation function.

Product Detail

1. The concentricity of the installation groove of food grade o-rings should be considered from two aspects: easy processing and no distortion.
2. The section size should be uniform, and lubricating oil or grease should be fully applied to the sealing part during each installation. Occasionally, a felt-ring refueling device saturated with lubricating oil can also be used.
3. Increase the cross-sectional diameter of food grade o-rings. Generally, the cross-sectional diameter of O-rings for dynamic seals should be larger than that of food grade o-rings for static seals; in addition, they should be avoided as seals for large-diameter pistons.
4. When twisting damage occurs under low pressure, a sealing ring can be used to protect the retaining ring.
5. Reduce the surface roughness of cylinder and piston rod.
