OxyGenie Oversize M12.1‑1.5 x 15mm Piggyback Oil Drain Plug Repair Kit — 304 Stainless, Self‑Tapping

The OxyGenie M12.1-1.5 x 15mm Oversize Piggyback Oil Drain Plug is a stainless-steel self-tapping repair kit that restores stripped oil pan threads quickly and creates a secure, leak-resistant drain plug assembly.

If the drain plug threads on your oil pan are damaged, replacing the pan is costly and time-consuming. This OxyGenie kit provides a machined stainless steel main plug plus a removable piggyback plug that mates to the new threads, letting you repair and retain a convenient drain point without welding or complex thread inserts. Built from 304 stainless and CNC-machined for consistent tolerances, the kit includes seals and an Allen wrench so you can complete the repair with basic tools.

How does this piggyback drain plug repair a stripped oil pan thread?

The oversized, self-tapping main plug cuts fresh threads into the damaged hole as it is installed, forming new engagement inside the pan. A secondary piggyback plug screws into the main plug to provide the removable drain point so normal oil changes remain easy.

• Self-tapping 304 stainless main plug forms new threads safely.
• Removable piggyback drain plug preserves traditional oil change access.
• Includes copper gasket and fluorine O-rings for a reliable seal.

What tools and torque are needed for installation?

Installation requires basic hand tools: a T-socket wrench for the main plug and the provided L-shaped Allen key for the piggyback plug. Tighten the main plug to the recommended torque to seat the threads and hand-tighten the piggyback plug for service access.

• Use the supplied L-shaped hex key for the piggyback plug.
• Recommended main-plug torque: about 14 ft‑lb (19 N·m) using a T-socket.
• Keep a wrench on the main plug when removing the piggyback during draining.

Will this kit fit my vehicle and how durable is the material?

The main plug is specified as M12.1-1.5 x 15mm, a common oversize repair dimension for many passenger cars and light trucks. Machined from corrosion-resistant 304 stainless steel, it resists rust and provides long-term hardness for repeated oil changes.

• Specification: M12.1-1.5 x 15mm main plug for oversize repairs.
• 304 stainless steel construction for corrosion resistance.
• Precision CNC cutting for consistent, repeatable fitment.

How do I install the OxyGenie repair kit safely?

Start with a clean, oil-free work area and follow a simple sequence: thread the main plug a few turns forward and backward to align, seat the plug until it bottoms out, then remove and clean loose shavings before final torque. After the main plug is torqued, fit the piggyback plug with its gasket and O-ring—hold the main plug steady when removing the piggyback during oil changes.

• Clean the pan and threads thoroughly before starting.
• Seat main plug, remove, clean debris (brake cleaner recommended), then torque to spec.
• Fit piggyback plug with copper gasket and fluorine O-ring included.

Who is this for: The OxyGenie oversize piggyback drain plug kit is aimed at DIY mechanics, independent service shops, and vehicle owners looking to repair a stripped oil pan thread without replacing the pan. It's ideal when you want a durable stainless repair that preserves a removable drain plug for routine oil changes while keeping costs and downtime low.
