Würth Rings copper for Oil Plug

These Würth copper rings prevent oil leakage. Suitable for external thread nut 12x1.5mm

Asbestos-free:
Asbestos-free copper rings can be used anywhere due to their corrosion resistance (except in the presence of certain strong acids). Through a specific form of preheating, the structure of the metal ring becomes even softer so that the ring can press itself into all uneven parts of the parts to be screwed, even under pressure.
