Overview

The Dsnaduo M14.1-1.5 x 15mm Oversize Piggyback Oil Drain Plug is engineered in stainless steel 304 with CNC precision. Its oversized, piggyback design supports re-threading worn oil pan holes while delivering a durable, reliable seal for ongoing maintenance tasks.

Built for longevity, this self-tapping repair kit resists heat and oil exposure, maintaining a clean, professional appearance. The kit includes essential components to complete a repair in one package, reducing the need for multiple trips to sources for parts.

What’s Included

  • 1x stainless steel self-tapping piggyback oversize oil drain plug (M14.1-1.5 x 15mm)
  • 1x L-shaped Hex Key Allen wrench for easy assembly
  • 2x fluorine o-rings for a tight seal
  • 2x red copper gaskets for reliable leakage prevention

Key Benefits & Real-World Use

This kit is designed for car owners and shops seeking a practical, field-ready solution for oil pan threads. You may notice:

  • Improved threading and a solid seal on worn or damaged oil pan holes
  • An all-in-one package that minimizes trips for separate components
  • Corrosion-resistant stainless steel that remains durable under heat and oil exposure

In real-life scenarios, the setup provides a neat, professional repair that can endure long-term use. It serves as a practical option for routine or emergency maintenance where a re-thread is needed without replacing the entire pan.

Installation At a Glance

  1. Clean the tank area around the hole completely.
  2. Insert the piggyback plug and turn forward a few rotations, then backward a few rotations to seat the thread.
  3. Remove the piggyback, clean the iron around the punch hole, then reinsert.
  4. Tighten the large oil plug screw with the T-wrench, then screw in the small plug screw to finish.

Quality You Can Expect

With CNC-cut tolerances and a robust stainless steel body, this repair kit emphasizes precision and durability. The design focuses on re-threading and resealing without requiring a full oil pan replacement, offering a practical maintenance option for compatible engines.
