OxyGenie Oil Drain Plug M14.2×1.5 15mm — Stainless Steel Self‑Tapping Double Oversize with Magnetic Piggyback

OxyGenie M14*1.5 Double Oversize Magnetic Piggyback Oil Drain Plug is a stainless steel, self-tapping drain plug that repairs severely stripped oil pan threads and provides a magnetic secondary drain for debris capture.

If your oil pan threads are chewed, over‑tapped, or otherwise unusable, this OxyGenie double oversize piggyback plug offers a permanent, mechanical repair without replacing the pan. It cuts a new, larger thread into the damaged hole, uses a copper crush washer plus an O‑ring for a dual seal, and includes a magnetic piggyback screw to collect ferrous particles from circulating oil.

How does this plug fix heavily stripped oil pan threads?

Instead of relying on a small oversize or temporary insert, the OxyGenie double oversize plug is engineered to cut deeper, stronger threads into the damaged opening. The larger outer diameter and self‑tapping geometry recreate a robust thread form that resists oil leaks and mechanical failure.

• Double oversize diameter cuts fresh threads into worn holes.
• Self‑tapping design eliminates need for external thread inserts.
• Stainless steel construction resists corrosion for long service life.

What prevents oil from leaking after installation?

This kit uses a dual‑seal approach: a copper crush washer at the flange provides a metal‑to‑metal primary seal, while an O‑ring on the piggyback screw supplies a secondary flexible seal. Together they significantly reduce the chance of seepage even on previously damaged pans.

• Copper crush washer seals against the pan flange when torqued.
• Fluorine O‑rings included for reliable secondary sealing.
• Recommended torque (~14 ft‑lb) ensures proper compression of seals.

How does the magnetic piggyback feature help the engine?

The removable piggyback plug contains a strong magnet that attracts ferrous particles circulating in the oil. By collecting metallic debris at the drain point, it helps reduce abrasive contaminants between oil changes and makes inspection and cleanup simple during service.

• Magnet captures iron filings and other ferrous debris.
• Removable piggyback screw makes inspection and cleaning quick.
• Continual passive protection while the vehicle runs.

How easy is installation and what comes in the package?

Installation follows straightforward steps: clean the pan threads, start the main plug a few turns forward and back, seat the plug fully, clean loose material, then torque to spec and fit the piggyback screw. The kit contains all necessary sealing parts and a wrench to complete the job.

• Included parts: stainless main plug M14.2 x 1.5 x 15mm, piggyback screw, Allen wrench.
• Seals supplied: two fluorine O‑rings and two red copper gaskets for secure sealing.
• Simple hand tools required; torque ~14 ft‑lb recommended.

Who is this for? The OxyGenie M14*1.5 double oversize magnetic piggyback oil drain plug is built for mechanics, DIY enthusiasts, and fleet technicians who need a durable, one‑time repair for badly damaged oil pan threads. It suits vehicles using M14.2 x 1.5 fittings where standard or single oversize plugs cannot get a reliable seal. If you want to avoid costly pan replacement, add debris‑capturing protection, and finish the repair with common tools, this kit delivers a practical, long‑lasting solution.
