Capture wear-generated debris in transmissions & gearboxes!
Early warning of failure in gears & bearings!

Magnetic chip collection is the most economical and direct form of lube system failure detection in use today. Usually located in a gearbox or reservoir drain plug location, the magnetic chip collector captures and retains particles for later removal and off-line analysis. This device is differentiated from the ubiquitous magnetic drain plug through the use of a unique self-closing valve, which permits the chip collector to be withdrawn without loss of lube or hydraulic oil. It is no longer necessary to wait until an oil change to assess the condition of critical gears and bearings. The chip collector can also be line-mounted, closer to the potential failure point, for fault isolation or even greater assurance of detecting a failure.

Why choose Tedeco magnetic chip collectors?

  • Economical and easy to install

  • Facilitates periodic inspection for failure or early wear

  • For new designs or retrofit onto existing lubrication systems

  • Unique self-closing valve...no loss of oil when removed

  • Available in a wide variety of thread sizes and diameters

  • Available with special adapter and hose for convenient “no spill” lubricant drainage

A wide range of standard designs are available. The detail dimensions should be checked against your own application for thread type, overall size, internal and external clearances, mounting plate thickness and mounting location (line mount versus reservoir or gearbox location)
