• Organized in a labeled plastic storage box for quick identification

How do these crush washers improve sealing and maintenance?

Crush washers deform slightly when torqued, creating a tight seal that fills minor surface irregularities and reduces leak paths at drain plugs and fittings. Compared with rubber gaskets, metal crush washers resist high temperatures, humidity, and oxidation while maintaining a dependable mechanical seal.

• Provides metal-to-metal sealing that tolerates heat and fluids
• Reduces loosening by distributing clamp force evenly
• Less prone to chemical degradation than many elastomer gaskets

What applications are these washers suitable for?

This assortment is designed for automotive oil drain plugs, hydraulic connections, gearbox drains, marine fittings, and many household or commercial appliances that rely on metal crush gaskets. The two-material selection lets you choose copper for superior conformability or aluminum for weight-sensitive or corrosion-prone environments.

• Automotive engine and transmission oil drain plugs
• Hydraulic hose and pipe fittings
• Marine hardware and electrical grounding connections

How is the kit stored and accessed during work?

maierke supplies the washers in a compact, transparent plastic box with individual compartments and printed labels identifying each size. This layout prevents mixing, speeds up part selection during service, and protects washers from dirt and damage between uses.

• Clear lid for fast visual inventory checks
• Printed size labels match compartment contents for quick access
• Portable case fits workshop shelves, toolboxes, or glove compartments

Who is this for: The maierke 1160PCS Crush Washer Kit is ideal for DIY mechanics, professional technicians, fleet maintenance teams, marine hobbyists, and anyone who performs regular fluid change or hydraulic maintenance. If you want a wide size selection, durable copper and aluminum options, and tidy storage to speed repairs, this kit delivers the parts and organization to keep routine jobs moving smoothly.
