R9 Oil Drain Plug 1/2 - The Plug Comes with Series of Smart Features, Benefits, high-Performance Sealing Technology, Patented Anti-Leak and Anti-Vibration Mechanism

I built a '64 Shelby Cobra Replica from a company called Factory Five. I put a Ford Racing Crate Engine (5.0 Coyote) in it and needed to use a low profile all aluminum Moroso Oil Pan. From the start it leaked from the oil plug. Nothing I did would stop it. I tried new plugs, tightening, loosening, tape, sealent, Sealing washers, and the leak would always return. I was afraid I was going to have to pull and replace the pan. I ran into this product, and for less than $10 is absolutely solved the leak and it hasn't returned. Additionally, with the design as it is, you don't need to torque the plug as tight, and it won't vibrate loose. I took it racing, and no leak even under that abuse. What a brilliant, yet simple idea. I'll be putting these in each of my cars, including my Daily drivers when the next oil change is done. Seriously, if you have a leak from the plug, stop looking for anything else and just order this. HIGHLY RECOMMEND!!!

I did not have leaks before so i cannot speak for its ability to stop them but it works as well as my stock bolt i had to mangle to get off and it seems to be made of decent quality metal with no burrs or odd threads.

👍🏻👍🏻👍🏻So right off the bat they don't list what the thread pitch is and I almost didn't buy it, it's 1/2-20 gm and the rest of the big 3 used this for eons. I had a leak from my drain plug I couldn't stop on a Pontiac 400 oil pan. Switched a few different plugs and gaskets through it and nada, even changed the pan: still leaked with new pan!!!Ordered one of these plugs and its sealed up nice and tight. I'm buying a second one for a spare to have around. I'm done buying part store specials.

Worked like a champ. Went from a drip after riding to dry as a bone

I have a motorcycle with a semi stripped drain plug and I was hoping this would be a more permanent fix. It does very well at letting the oil drip into a nice puddle under the bike. I guess I’ll go back to the original drain plug wrapped with Teflon tape. At least that doesn’t leak. I’m going to get a 1/2-20 oversized Dorman plug for a permanent solution.

I had previously purchased a standard type plug and unfortunately didn't hold up very well. This plug is working great.

It's inappropriate to describe my 1-star rating as "I hate it." It simply means that in my circumstance it didn't work. I have a 1995 F-150 4.9 liter in-line 6-cylinder or what used to be referred to as a "300 CID six." My F-150 has 98,000 miles on it, has been garaged, and has not been abused. The old plan has not been damaged. The Amazon website states this drain plug is the fit for my truck, but it leaks after being properly installed.

Worked great. Fixed the leaking problem
