Sealing rubber O-rings for hydraulic and pneumatic units GOST 18829-73,GOST 9833-73 are manufactured for working in adjustable and fixed joints of hydraulic, fuel,  oiling and pneumatic devices  at temperatures  -60 + 200 depending on the rubber group  and at pressure up to 50 MPa in fixed joints and up to  32 MPa in adjustable joints in mineral oils, liquid fuel,  dispersoid solutions, oiling, fresh and seawater; up to  40 MPa in fixed joints and up to 10 MPa in adjustable joints in compressed air.

Sealing rubber O-rings for hydraulic and pneumatic units GOST 18829-73, GOST 9833-73: nominal ring sizes in accordance with GOST 9833-73 are defined by two parameters: inside diameter and annular cross-section. In symbolic notation the inside diameter is round upwards, the annular cross-section notion is multiplied by 10. Thus nominal ring sizes mentioned in symbolic notation are:

- inside diameter  3,8mm  allowing -0,2 mm.

Also our enterprise manufactures quality silicone oil resistant tings.

If required you can order any ring of the below listed:

Recommendations concerning assembly and exploitation of Sealing rubber O-rings for hydraulic and pneumatic units GOST 18829-73, GOST 9833-73.

Кольца резиновые

While assembling sealing rubber O-rings for hydraulic and pneumatic units GOST 18829-73, GOST 9833-73, rubber rings should be protected from warping, curling and from mechanical damages and cuts.

General assembly scheme if provided on the picture:

  1. set screw;
  2. O-ring (secondary adjustable sealing)[2];
  3. finger which rotates the adjustable ring  4; 4) adjustable ring;
  4. stationary ring;
  5. O-ring  (secondary sealing);
  6. frame;
  7. finger keeping the stationary ring  5;
  8. bushing;
  9. spring group which presses the adjustable ring against the stationary one.

The surfaces of the counterparts should be clean, should not contain abrasives and corrosives. The surface is recommended to be oiled with oiling that is nonreactive with the ring materials or hydraulic fluids that have good oiling properties. 

During assembling the ring goes on the thread of screw, it is necessary to apply work holders covering the thread of screw.

Tools for ring assembly are made of expanded plastic or soft metal with rounded edges.

Rubber sealing rings can be assembled with protective rings or without them, it depends on exploitation conditions. 

After disassembly of the exploited seal assembly it is advised not to use it for the second time. 

The chemical compounding of the working environment should comply with GOST and technical documentation for the seal assembly, device.

If the gas proofing of all the rubber rings (rings, collars pads) is broken simultaneously their replacement provides only a temporary positive effect, this means that the hydraulic fluid contains aggressive components. 

Sealing rubber rings have a tendency to bloat (change their mass) under influence of hydraulic fluids more or less depending on the rubber group.

Bloat degree of rings is checked by placing them in a solution of isooctane and methylbenzene in the ratio 7:3 (by volume) during 24 hours at temperature 23±3 °С. For 1, 2, 3 type rubber the bloat degree (mass change) cannot exceed 35%.

The sealing rings (sealing rubber O-rings for hydraulic and pneumatic units GOST  18829-73, GOST 9833-73) are tested by being placed into petroleum, kerosene oil, dissolvers, and other liquids of this type is impermissible. .


If you haven’t found a required ring in this list - contact our managers and double check the product availability. It is possible that we had finished manufacturing this detail before the list was updated. In terms of an order we can manufacture any ring type including the mold equipment price.

If you want to set up the manufacture of these items at our production plant contact the engineering department to estimate the price of a mold.
