For hydraulic or pneumatic units to function properly, they must be closed systems with no pressure loss whatsoever. During production, it is often necessary to drill auxiliary bores for all channels required in the system. For these systems to function properly and to prevent pressure losses, these bores must be sealed tightly afterward. Component specialist norelem now offers reliable sealing plugs for this task.
norelem offers steel and stainless steel sealing plugs in numerous sizes, designed for installation with an insertion pin (in picture at right).
Sealing plugs from norelem work on the principle of pressure and expansion, in which a ball integrated in the expansion sleeve serves as the expansion element. The sealing plugs are equipped with a serrated sleeve, which expands when the ball is pressed in. This causes the sleeve to expand until the bore is sealed, and the sleeve is anchored in the base material. The metal seal created in this way can withstand continuous pressure up to 448 bar without the need for additional sealants. The sealing plugs can be removed later if necessary.
Sealing plugs are used primarily in bores of fluid technology systems, for example in automotive construction, industry, aeronautics, and machine tools, to prevent liquids or gases from leaking. The sealing plugs are available in various sizes, in steel or stainless steel versions.
Key features of sealing plugs from norelem include:
- For permanent plugging and sealing in fluid technology
- Based on the principle of pressure and expansion
- Reliable seal up to a continuous pressure of 448 bar
