Screw Plugs

Liquid or gaseous media are used in vehicle engineering, in many machines and plants: for lubrication, for power transmission, for cooling or heating plants or their components. Screw plugs reliably seal the openings in these systems.

Along with many normed parts, specific solutions which meet specialised requirements for construction, the use case and assembly are used here.   

The seal can be affected using sealing edges, metallic sealing rings, thread coatings, polymer sealants or through a suitable combination of these technical details. We will be glad to consult with you regarding your selection of a suitable system.

Depending on the piece count and the dimensioning, the manufacture of parts can be affected using cold forming with subsequent processing, classical machining as lathed components or in the case of very large dimensions through machining forged raw components.
