This O-ring is the sealing element that sits at the oil reservoir joint of SKF manual injectors. It keeps lubricant inside the reservoir and holds internal pressure while the tool is being pumped. When it wears out or gets cut, oil escapes, contamination enters and the injector stops dosing correctly, so it is a part worth keeping on the maintenance list.

The part code has two parts. The number 920100 covers the family of spares for manual injectors, and the suffix separates the individual versions within that family, which is why you see 920100 B-1 and 920100 B-2 listed separately. Match the code against the parts diagram or the injector data sheet before ordering. If the code is hard to read, send the full string through WhatsApp and our team will confirm which one applies to your tool.

These seals turn up in the routine service of manual oil injectors in workshops, plants and agricultural operations, and in the upkeep of SKF lubricating equipment for bearings, chains and guides. They are also fitted by shops that service hydraulic tools of other makes, since the reservoir joint is one of the points where performance is won or lost. In practice, the O-ring is changed during planned shutdowns or as soon as the reservoir starts weeping.

Selection starts with the injector model and the code shown in the parts diagram. The elastomer has to be compatible with the oil or grease in use, so check that before fitting. On assembly, clean the groove and seat, put a thin film of lubricant on the ring and make sure it is not twisted. Closing the reservoir with a torque wrench set to the specified value keeps the ring from being crushed out of shape. A damaged ring means the pump loses efficiency.

Cross-referencing to another brand is possible when the standardized dimensions and the material line up. Inner and outer diameter on their own do not settle it; section thickness and hardness count as well. Standard sizes are easy to find for hydraulic tools, but chemical and thermal resistance still need to be verified. We can advise on interchangeability, though staying with the original code is the safer route to avoid early failures.

For a quote, send the code 920100 B-1 or 920100 B-2 to MR Industrial Accessories by WhatsApp or email. If you are not sure which one fits, include the injector model and a photo of the parts diagram and we will help you pin it down. We supply customers throughout the United States and in several Latin American countries.
