Solid replacement part

Lost my original drain plug during an oil change. This was a cheap and effective replacement. Fits my sedan's oil pan perfectly.

Exactly as described

No surprises here. It's a standard hex flange plug that does exactly what it is supposed to do. The rubber seal prevents dripping effectively.

Perfect fit for my truck

Ordered the M14 size for my pickup's differential. The threads matched perfectly and the flange sat flush against the housing. No leaks after a 500-mile test drive.

Good quality, fast shipping

The zinc plating looks durable and the included washer is a nice touch. Took off one star because the hex head was slightly tighter than expected, requiring a specific socket.

Holds up under pressure

Used the M16 on a high-performance engine build. It handled the oil pressure and heat cycles without any issues. Very reliable component.

5 FAQ

Q: Can I use this on an aluminum oil pan without stripping threads?

A: Yes, provided you do not overtighten it. The steel plug is harder than aluminum, so hand-tighten first and use a torque wrench to avoid damaging the pan threads.

Q: Do you sell the magnetic tip version of this plug?

A: This specific listing is for the standard non-magnetic flange plug. Please check our 'Magnetic Drain Plugs' category for versions with built-in magnets to catch metal shavings.

Q: Is this suitable for synthetic oil?

A: Absolutely. The materials used are compatible with conventional, synthetic blend, and full synthetic motor oils.

Q: What is the torque specification for the M12 size?

A: For standard carbon steel M12 plugs, we generally recommend a torque between 25-30 Nm, but please consult your vehicle's specific service manual for exact requirements.

Q: Does this come with a new copper or rubber washer?

A: Yes, each plug comes with an integrated rubber O-ring seal designed for reuse, though we recommend inspecting it before every installation.
