The Smart-O® Advantage
Smart-O® is the most advanced oil drain plug on the market and offers a complete solution for changing oil drain pan plugs.
Complete Coverage in 18 Sizes
Our 18 plug sizes cover over 30,000 European, British, American, Japanese and Korean car makes and models, offering one of the most comprehensive drain plug ranges and covers 99 per cent of vehicles on the road today.
The O-Ring Protection
The patented O-Ring on a Smart-O® Plug offers intelligent protection. When exposed to engine oil, the ring expands from 10 – 20 per cent, sealing the oil pan from inside the thread to secure the oil inside the pan.
The O-Ring expands in response to heat and hydrocarbons, filling the air gap, blocking any potential leakage between threads and producing a vibration and impact resistant seal that exceeds any other protection on the market.
A Smart Seal
Smart-O® Plugs exhibit the most powerful sealing performance found in any oil drain plug. The O-Ring seal has been proven to survive the most adverse conditions.
Tests include incorrectly installing our plugs in cars that were then driven across the United States for more than 4,500 kilometres in severe heat or extreme cold, conditions that would cause standard oil pan plugs to fail almost immediately and lead to oil leakage, sudden oil loss, engine damage and the loss of the plug.
Even under these circumstances, the plugs upheld their anti-leak, vibration-resistant features, held firmly in the pan, and kept the oil safely in the oil pan of the vehicle.
The O-Ring is designed to prevent self-loosening even from excessive vibration.
The Smart-O® Plug has been subjected to 9G vibrational forces and maintained a firm seal in the oil pan. The plug also underwent the junkers test.
After being subjected to excessive transverse vibrations, Smart-O® did not loosen completely and could be removed by hand turning.
Junkers test conducted by the Oakland University Fastening & Joining Institute and Spectrum Technologies, Michigan.
Preventing Wear and Tear
Quickly installed oil pan plugs can often be mismatched in size to the oil pan, causing damage to the threads.
Even correctly installed plugs can leave stripped oil pan threads after many years of plug replacements.
The intelligent O-Ring seal avoids this with a design that exerts no pressure on the threads, softly expanding to fill and seal the pan.
An Easy Fit
Oil pan plugs are often mismatched to the pan with improper sizing leading to thread damage. Smart-O® Plugs are designed for the busy auto service professional: each plug is identified with a clear headmarking.
Our plug range of 18 sizes will fit most automobiles on the road today.
To find the right plug for any vehicle, you only need the oil pan’s thread diameter and thread pitch.
Oil pan plugs are often overtorqued, causing wear and damage to the pan. Our Smart-O® Plug features SmarTorq where the O-Ring increases the prevailing torque on the plug itself, reducing the need to overtighten the plug in the pan.
Tests revealed that Smart-O® showed higher prevailing torques during tightening and loosening cycles compared to OEM and aftermarket plugs.

Reducing Risk and Inventory
With a range of a mere 18 plugs, the Smart-O® design cuts down on the need for excessive storage and reduces the risk of incorrect installation, oil pan thread damage, oil leaks and catastrophic oil loss, or engine damage from oil leakage.
Smart for the Environment
Engine oil is a major source of water pollution. An oil spill of 3.8 litres can contaminate 3.8 million litres of water.
Used motor oil can contain chromium, lead, petroleum hydrocarbons, aromatic hydrocarbons, or zinc and is highly carcinogenic.
Smart-O® offers a smart preventative measure by keeping the oil in the oil pan and out of the environment. In addition, the Smart-O® Plug is reusable, recyclable, ROHS compliant, and its black coating is free of toxic Cr6.
Smart-O® stands for the highest quality. Our plugs and related components are manufactured in certified facilities to ISO/TS standards to ensure they conform to the strictest automotive standards.
