M14 Copper Crush Washers 30 Pack Sealing Rings for Engines
✔️ Copper M14 seals 20mm OD 14mm ID 1mm thick pack of 30

This thirty piece box of copper sealing rings handles stubborn leaks on automotive oil pans, fuel lines, and hydraulic circuits. Shop crews trust these flat metal gaskets because the pure copper composition crushes predictably under torque to seal off messy fluid drops. Each ring measures 20mm 0.79 inches outward, spans 14mm 0.55 inches at the center hole, and sits just 1mm 0.04 inches thin. The bundle packs enough replacements for multiple jobs around the garage, saving you trips to the parts counter when you run dry on critical fittings.

✅ Pure copper alloy stands up to engine heat and coolant spray without warping or losing shape
✅ Uniform disk profile distributes clamping force evenly to guard soft aluminum pan surfaces
✅ Centered bore aligns straight with common M14 0.55 inch metric hardware for quick bench assembly
✅ Ductile metal body flexes around rough bolt seats to hold tight against vibration and road shake

💡 How do copper sealing washers stop drip prone fuel lines from giving mechanic buddies trouble?

These handy malleable discs yield just enough to lock down wet joints without fighting the bolt thread.

- Soft metal core flattens out to plug tiny casting flaws right at the oil pan flange

- Heat tolerant build survives summer baking temps without shrinking back into sticky puddles

- Rough edge free rim keeps hands safe while lining up spark plug wire boots smoothly
