Rubber sealing rings
Rubber sealing rings GOST 9833-73 (18829-73)
O-ring, rubber sealing rings for hydraulic, fuel, lubrication and pneumatic devices.
They are efficient at temperatures from -60°С to +200°С and movement speed up to 0.5 m/s in various environments at pressure:
- up to 50 MPa in fixed joints and up to 32 MPa in movable joints in mineral oils, liquid fuels, emulsions, lubricants, fresh and sea water.
- up to 40 MPa in fixed joints and up to 10 MPa in movable joints in compressed air.
For travel speeds up to 5 m/s in any specified working environment.
Rings are manufactured in the following accuracy groups:
1 - for movable joints
2 - for movable and fixed connections
Notes:
1. The temperature range of operation of the ring for rubber of all groups can be extended by agreement between the consumer and the manufacturer.
2. Rubber of group 3 is recommended for operation in oils at temperatures up to -60 ° С, and in other environments - up to -50 ° С.
3. Rubber of group 7 is recommended for work in fixed joints in air at a pressure of up to 0.63 MPa in the specified temperature limits and in water up to a temperature of 120 ° C; its use is allowed with a limited quantitative effect of mineral oils.
Legend: d1-d2-d3 GOST 9833-73, where
d1 - rod diameter (mm);
d2 - cylinder diameter (mm);
d3 is the cross-sectional diameter of the ring multiplied by 10 (mm).
