Why Choose These Crush Washers?
- Reliable Sealing: The crush washer seats snugly between the oil drain bolt and oil pan, forming a pressure-tight seal that prevents oil seepage after every oil change.
- Copper Construction: Solid copper material offers excellent heat resistance, corrosion resistance, and long-lasting sealing performance in demanding underbody environments.
- M14 Standard Fit: 14mm inner diameter × 20mm outer diameter — always compare dimensions with your original washer before ordering to ensure the right fit.
- Bulk Value Packs: Available in 10-piece or 20-piece quantities, giving you enough washers for multiple oil changes, home garages, or workshop use.
- Easy Replacement: Simply remove the old washer, slide the new one onto the drain bolt, and torque to specification — no special tools required.

Frequently Asked Questions
Q: What vehicles are these M14 copper crush washers compatible with?
A: These washers are compatible with any vehicle that uses an oil drain plug washer with a 14mm inner diameter and 20mm outer diameter. They are commonly referenced for selected VW and Audi models using OE number N0138157. Always verify your vehicle's original washer dimensions and OE number before purchasing to ensure compatibility.
Q: Do I need to replace the crush washer every oil change?
A: It is good practice to replace the crush washer at each oil change or whenever the existing washer appears flattened, deformed, or damaged. Reusing a compressed washer can compromise the seal between the drain bolt and oil pan. Having a multi-piece pack on hand ensures you always have a fresh washer ready for each service.
Q: What is the difference between the 10-piece and 20-piece options?
A: Both options contain the same M14 copper crush washers (14×20mm). The 10-piece pack is ideal for personal vehicle maintenance, while the 20-piece pack offers better value for home garages, mechanics, or workshop environments requiring multiple oil changes over time.
