The spare O-ring for the SKF manual injector reservoir is a sealing component that fits on the oil reservoir joint of manual injectors. Its function is to prevent leaks and maintain internal pressure during lubricant injection. It is a critical part for preventive maintenance: a worn or damaged O-ring causes oil losses, contaminant ingress and dosing failures. It is available as a genuine SKF spare part for the manual injection tools that MR Accesorios Industriales stocks.
The designation of these spare parts combines a base number and a suffix that indicates the variant. In the examples 920100 B-1 and 920100 B-2, the code 920100 identifies the family of spare parts for manual injectors, while B-1 and B-2 distinguish specific versions or sizes within that family. To ensure compatibility, always verify the exact code shown in the equipment parts diagram or in the injector technical data sheet. If you have doubts, send us the complete code via WhatsApp and we will confirm it.
These O-rings are used in the maintenance of manual oil injectors in workshops, industrial plants and the agricultural sector. They are common in the service of SKF equipment for lubricating bearings, chains and guides. In Argentina, they are replaced during scheduled maintenance shutdowns or when leaks appear in the reservoir. They are also used in workshops that repair hydraulic tools of different brands, since reservoir sealing is a critical point for equipment performance.
To select the right spare part, you must identify the manual injector model and the O-ring code according to the parts diagram. The chemical compatibility of the material with the oil or grease used is essential: verify that the elastomer is suitable for the lubricant. During mounting, clean the groove and seat well, lightly lubricate the O-ring before fitting it and avoid twisting. A calibrated torque wrench helps prevent deforming the part when closing the reservoir. If the O-ring is damaged, the pump loses efficiency.
Regarding equivalences, SKF O-rings can be replaced by spare parts from other brands as long as the standardized dimensions and material match. The inner and outer diameter alone is not enough: the section thickness and hardness also matter. For hydraulic tools, O-rings are commonly found in standard sizes, but it is advisable to validate chemical and thermal resistance. At MR Accesorios Industriales we can advise you on interchangeability, but we always recommend using the original code to avoid premature failures.
If you need this spare part, send the code 920100 B-1 or 920100 B-2 via WhatsApp to MR Accesorios Industriales. We will quote you and coordinate delivery. We can also help you identify the correct O-ring if you send us the injector model and a photo of the parts diagram. With more than 80 years in the business, we know that a small spare part prevents big shutdowns.

Frequently Asked Questions
- How do I know which O-ring my SKF manual injector needs?
- You need to check the equipment parts diagram or the injector identification plate. The O-ring code usually appears in the maintenance manual. If you cannot find it, send us a photo of the reservoir and the injector model via WhatsApp and we will help you identify it.
- Can it be replaced with a generic O-ring?
- Only if the standardized dimensions match (inner diameter, outer diameter and thickness) and the material is compatible with the lubricant. To ensure performance, we recommend using the genuine SKF spare part. If you choose an alternative, validate the hardness and chemical resistance before installing it.
- How often is this spare part replaced?
- There is no fixed interval: it depends on use and care. It is replaced when leaks appear, the O-ring looks dry, cracked or deformed, or during preventive maintenance of the injector. Check it at every service and at any sign of oil loss in the reservoir.
