Magnetic Drain Plugs were pioneered by Lisle Corporation in the 1930's. Lisle MAGNETIC PLUGS are similar to standard pipe or straight thread drain plugs with one important difference – a permanent magnet is fastened to the plug body. This magnet attracts and holds abrasive, ferrous metal particles preventing their circulation through the lubrication or hydraulic system.

These abrasive, ferrous metal particles appear in lubricating or hydraulic systems as a result of the following conditions:

  • The constant flaking effect of normal wear of moving parts.
  • Particles not removed by flushing operations after boring or machining.
  • Chipping due to sub-surface casting flaws.
  • Minute component breakdown caused by stress usage.

Usually a combination of factors accounts for the presence of these particles that cause excessive wear to vital components unless they are removed. By holding these particles, Lisle MAGNETIC DRAIN PLUGS prevent excessive wear to the system's components.

World War II proved the worth of MAGNETIC DRAIN PLUGS. Lisle MAGNETIC PLUGS helped protect American Jeeps, tanks, trucks, aircraft and other wartime equipment in rugged operating conditions around the globe.

Lisle manufactures MAGNETIC PLUGS in a wide variety and range of sizes, magnet types, and body styles.

Standard Lisle MAGNETIC PLUGS (many of them stock items) are shown in this catalog. In addition to these standard parts, Lisle engineers will design MAGNETIC ASSEMBLIES to meet specific applications that may not be covered by a standard part.

Today, Lisle MAGNETIC PLUGS are used by numerous manufacturers of gear boxes, transmissions, engines, and hydraulic systems for the automotive, aircraft, agricultural and machinery industries. Typical applications include:
