Magnetic screw plugs from heinrichs drehteile
In every oil circuit, fine metal particles are created through abrasion - an invisible danger to bearings, gears, seals, and hydraulic components. Our magnetic screw plug offers a simple but highly effective solution: The powerful, securely pressed or glued magnet attracts metallic impurities from the oil, thus preventing premature wear and expensive repairs.
Why magnetic screw plugs?
- Maximum protection for your machines
Fine metal particles are reliably extracted from the oil before they can cause damage. This reduces wear and extends the lifespan of your equipment. The risk of clogging in nozzles, orifices, and lubrication channels is significantly minimized. - Clean oil for better lubrication and efficiency
The cleaner the oil, the better the lubrication. Fewer contaminants mean less friction and increased system performance. - Easy integration & versatile applications
Magnetic screw plugs can be easily retrofitted into existing systems—ideal for engines, gearboxes, hydraulic systems, and industrial applications. - Reduced maintenance costs & increased operational safety
Less abrasion in the oil reduces the frequency of necessary oil changes and minimizes the risk of damage, saving both time and money. - High-quality materials & durable quality
Made from a variety of robust materials, the magnetic screw plug withstands even the toughest conditions and ensures long-term performance.
