10pcs 16mm Inner Dia Copper Flat Washer Line Seal Fitting Fastener

Specification:

• Essential for Automotive and Small Engine Repairs.
• Washers made from copper are often used within piping, electronics, household products, and biomedical applications as copper is malleable and ductile– a biostatic surface that is a good conductor of heat and, when very pure, a good conductor of electricity.
• Copper Provides a Tighter Seal and Greater Heat Endurance than Steel and Rubber Washers.
• These obviously have industrial uses, but we also sell them to weavers, artisans who make wall hangings, a lady who uses them to accent macrame hanging baskets etc.
