Standard For Propane O-Rings

The Standard of propane o-rings includes American Standard O-ring, Japanese Standard O-ring, European Standard O-ring, national standard o-ring and AS568 o-ring. According to the o-ring industry standard, there are the following o-ring standard tolerances, ID * Line diameter CS, in MM.

1. o-rings standard, o-rings standard specification, o-rings national standard, o-rings standard, propane o-rings standard internal diameter standard:

Id 0.00-1.79 mm o-rings standard tolerance +/-0.10

Id1.80-6.29 mm o-rings standard tolerance +/-0.13

Id6.30-10.59 mm o-rings standard tolerance +/-0.14

Id10.60-18.99 mm o-rings standard tolerance +/-0.17

Id19.00-31.49 mm o-rings standard tolerance +/-0.22

Id 31.50-41.19 mm o-ring standard tolerance +/-0.30

Id 41.20-51.49 mm o-ring standard tolerance +/-0.36

2. o-rings standard, o-rings standard specification, o-rings national standard, o-rings standard, propane o-rings standard:

The Standard Tolerance for type CS 0.00-1.79O is +/-0.07

The Standard Tolerance for type CS 1.80-2.64O is +/-0.08

The Standard Tolerance for type CS 2.65-3.54O is +/-0.09

The Standard Tolerance for type CS 3.55-5.29O is +/-0.10

The Standard Tolerance for type CS 5.30-6.99O is +/-0.13

The Standard Tolerance for type CS 7.00-8.000 o-rings is +/-0.15

The Standard Tolerance of the CS 8.01-10.00o type coil is +/-0.20

Because the hardness of the propane o-rings material is the most important index to evaluate the sealing performance, the hardness of the propane o-rings determines the compression capacity of the o-rings and the maximum allowable extrusion gap of the groove. Since the nitrile seal of Shao A70 can meet most of the application conditions, the hardness of the o-ring is closely related to the o-rings standard. When the o-rings is selected, the higher the working pressure is, the smaller the maximum allowable extrusion clearance is. If the clearance exceeds the allowable range, it will result in extrusion or even damage of the o-ring. The general compression ratio is about 20%.
