Professional Copper Washer Seal Kit

Welcome to Auto Luxe Shop! Ensure a leak-proof seal every time with our Professional Copper Washer Gasket Assortment Kit, the ultimate hardware solution for automotive, marine, and industrial applications. This comprehensive set features high-quality, flat-ring copper washers in various metric sizes—from M4 to M14—specifically designed for sump plugs, fuel lines, and hydraulic fittings. Unlike standard steel washers, these soft copper gaskets deform slightly under pressure to create a tight, airtight seal that prevents oil leaks and fluid seepage even under high-temperature conditions. Organized in a rugged, transparent divider box for quick identification, this kit is an essential addition to any garage or workshop for reliable, professional-grade maintenance and repair.
