FDA Food grade silicone rubber ring

1.General Introduction of Rubber Ring

O-Rings are used in sanitary pipeline systems for the Auto, Food, Dairy, Beverage, Pharmaceutical pump, railcars, truck, washing machine, instrument and meter, mine equipment, pipeline, household appliances, automobile, steamboat, industrial electrical equipment, building door& window, construction machinery, construction bridges and tunnel. Rubber material : EPDM, NBR, FKM Fluoroelastomer, Buna-N, PTFE, Silicone and so on.

2.Product Description:

3.Material :

Silicone (VMQ)
Good resistance to water (up to 100 °C), aliphatic engine and transmission oils, animal and plant oils and fats. VMQ is generally not resistant to fuels, aromatic mineral oils, steam (short term up to 120 °C possible), silicone oils and greases, acids and alkaline compounds.

4.Note:

Avoid to damage the O-ring during installation, because this will cause leakage. Pay attention to the following:

• The O-ring must not be expanded to its elongation Maximum.
• Edges must be burr-free, angles and radii applied smoothly.
• Dust, dirt, metal chips and other particles must be removed.
• A suitable grease to be applied to the assembly surfaces and O-rings.
• Elastomer materials are made smoother if they are heated in oil or hot water to approx. 80 °C. This makes that it easier to stretch the O-ring for assembly.
• The O-ring should not be rolled over assembly surfaces. Ensure the O-ring is not twisted as it slots into the groove.
