M15x1.5 Oil Drain Plug with Copper Crush Washer Assembly

Brief Overview

This metric oil drain plug assembly delivers the exact sealing performance your workshop needs for engine maintenance and oil changes. The kit includes both the threaded plug and copper crush washer—two critical components that work together to prevent oil leakage at the sump. If your inventory requires additional sizes, we also stock larger metric drain plugs to cover the full range of automotive applications.

Key Features

• Metric M15x1.5 thread specification – Direct compatibility with vehicles engineered to this standard
• Hexagonal head design – Six-point socket contact for controlled tightening without rounding
• Integrated sealing flange – Distributes clamping force across the sump surface to prevent deformation
• Copper crush washer included – Single-use sealing element that compresses under torque to create a metal-to-metal seal
• Zinc/chrome plating – Corrosion resistance for extended service life in diverse climates
• Complete assembly – No need to source washer separately; ready to install

Business Advantages for Resellers

This is a consumable maintenance item with high turnover potential:

• Recurring demand – Every oil change cycle requires a fresh washer; customers return regularly
• Low inventory footprint – Compact packaging allows high-margin stock density
• Paired sales opportunity – Bundle with oil filters and engine oil for complete service kits
• Margin-friendly – Minimal material cost vs. professional installation value
• Inventory depth strategy – Stock multiple sizes (M17x1.5 and M20x1.5 variants) to capture full vehicle range and prevent lost sales

Why This Matters

Oil drain plugs fail due to improper resealing—a single reuse of the crush washer or cross-threaded installation can lead to oil loss and customer complaints. This assembly eliminates guesswork by providing both components in one transaction. The copper washer's soft metal construction ensures it deforms properly under torque, conforming to the plug's sealing face for a reliable joint every time.

Stock this assembly for steady, profitable turnover. Every mechanic needs it; every customer expects it included.
