Anti-leak & Anti-vibration: seals the oil pan from the inside & counteracts vibration.

Wide application: The oil drain plug is suitable for most vehicles, cars, motorcycles, trucks, etc.

Made of high-quality materials, which have good heat & corrosion resistance.

Faster installation: the SmarTorqª simple & unified torque setting makes it easy to install.

Excellent performance: The oil drain plug has good sealing performance & can effectively prevent oil leakage.

Patented sealing & locking mechanism that enables the plug to resist vibration & seals more effectively.

Engine & Oil Pan Protection: the seal & anti-vibration mechanism reduce risk of engine damage due to catastrophic oil loss caused by loss of drain plug.

Re-usable: the plug can be reused multiple times.

Eco-friendly: reduces risk of oil leaks & less material waste due to the re-usable seal. The black coating is free of harmful Cr6, so parts can be easily recycled.

Instructions for use:

  1. Ensure correct fit by verifying that SMART-O-PLUG has the same thread diameter & thread pitch of your original sump plug
  2. Use a torque wrench & apply OE specified torque. Or refer to SmarTorq specs: 24.4 Nm (petrol engines) / 40.6 Nm (diesel engines). DO NOT torque plugs above 40.6 Nm
  3. Polymer washer is not reusable, always replace washer with every oil change
  4. Plug is reusable but only if O-ring is intact, not worn & not damaged.
  5. Always inspect plug threads & O-ring surface before installation & reuse
  6. Do not install plug in oil pans with heli-coil inserts or in thin steel oil pans where O-ring might protrude beyond the thread area, preventing the O-ring from working properly

1. Remove the old drain plug. Clean the oil pan thread and face area with a clean cloth.

2. Inspect the SMART-O® O-ring. Ensure the O-ring is seated correctly in the groove. Do not apply thread sealant or PTFE tape.

3. Thread by hand first. Always start threading by hand to avoid cross-threading. Thread until the plug head contacts the oil pan face.

4. Tighten with SmarTorq™. Petrol engines: 24.4 Nm (18 ft-lb). Diesel engines: 40.6 Nm (30 ft-lb). Do not exceed these torque values.

5. Check after first run. After the first run, inspect for leaks. The O-ring expands slightly in contact with engine oil to support seal integrity.

Use the fitment check as a starting point, then confirm thread size before ordering if anything is unclear.
