Drain Plug Configuration
Male NPT Thread
Precision-machined male NPT threads provide secure engagement with compatible female-threaded drain openings.
Integrated Magnet
The internal magnetic element attracts and retains ferrous wear particles suspended in compatible lubricants and fluids.
Hex-Style Head
The wrenching surface allows convenient installation, removal, inspection, and cleaning during routine equipment maintenance.
Construction Details
The drain plug is manufactured from durable steel with precision-machined male NPT threads for secure installation into compatible threaded equipment openings.
An integrated magnetic element attracts and retains ferrous wear particles, allowing accumulated debris to be inspected and removed during scheduled maintenance.
The compact threaded body and hex-style wrenching surface provide straightforward installation and servicing using appropriate hand tools.
How the Magnetic Plug Helps

Thread Selection
Match the Drain Opening
Select the drain plug based on the exact NPT thread size of the mating female drain opening. Similar-looking thread sizes are not interchangeable.
Use Proper Thread Sealing
Use an appropriate thread sealant where required for the application, taking care not to interfere with proper plug installation or equipment operation.

Our fitting and industrial product specialists can help review your NPT thread size, drain-port configuration, fluid compatibility, operating conditions, and maintenance requirements before you order.

What does a magnetic drain plug do?
The integrated magnet attracts and retains ferrous metal particles circulating within compatible lubrication or fluid systems.
What material is the plug made from?
The supplied product information identifies durable steel construction.
What thread type does the plug use?
The plug uses male NPT threads for installation into compatible female NPT drain openings.
What thread sizes are available?
The supplied product information identifies 3/8-18, 1/2-14, 3/4-14, and 1-11 1/2 NPT configurations.
What type of debris will the magnet collect?
The magnetic element is intended to attract ferrous metallic particles, such as iron or steel wear debris.
Will the magnet collect aluminum or other non-ferrous particles?
No. Magnetic drain plugs primarily attract ferrous metals. Non-ferrous materials such as aluminum, brass, or copper are not normally attracted by the magnet.
How often should the magnet be cleaned?
Inspect and clean the magnetic surface during routine equipment service or fluid changes, or according to the equipment manufacturer's maintenance schedule.
Why inspect the collected debris?
The amount and type of metallic debris collected can provide useful information about component wear and equipment condition during routine maintenance.
Should thread sealant be used?
Use an appropriate thread sealant where required by the equipment or application, and follow the manufacturer's recommended installation practices.
What should I verify before ordering?
Confirm the exact NPT thread size, drain-port configuration, fluid compatibility, operating pressure, temperature, and equipment requirements.
