Sealing plug sleeve stainless steel, ball steel Product description When manufacturing a hydraulic or pneumatic aggregate, auxiliary holes are needed for the production process, e.g. so that all the channels required for the respective application can be precisely drilled into the workpiece. These auxiliary holes must be absolutely tightly sealed again and be able to withstand extremely high pressure so that the component can function properly later on. Material Sleeve: stainless steel 1.4305. Ball: ball-bearing steel. Version Sleeve: bright. Ball: tempered. Note Sealing plugs are used to seal holes in fluid technology - e.g. auxiliary holes in hydraulic units - quickly, securely and cost-effectively. These seals have a serrated sleeve that expands when the ball is pressed in, expanding the component until the bore is sealed and anchoring itself in the base material. This creates a tight metallic seal that can withstand the highest pressure. Suitable for base materials with low to medium hardness. They are usually installed manually using an insertion pin. Accessory Insertion pin 28080-90.
