HPS Performance Products AW20M Aluminum Crush Washer - 20mm

The HPS Performance Products AW20M is a precision-engineered 20mm metric aluminum crush washer designed for reliable sealing in high-pressure automotive and powersports applications. These single-use sealing washers are specifically manufactured to deform under compression, creating a permanent, leak-proof seal on banjo fittings, drain plugs, and other threaded connections.

Key Features:

• High-quality aluminum construction for superior sealing performance
• 20mm metric size compatible with standard banjo bolts and drain plugs
• Suitable for high-pressure fluid and air applications
• Compatible with water, coolant, engine oil, transmission fluid, and most petroleum-based fuels
• Designed to crush and conform to mating surfaces for maximum seal integrity
• Corrosion-resistant aluminum material for extended service life

HPS aluminum crush washers are essential replacement components for brake line installations, oil cooler lines, turbocharger oil feeds, fuel system connections, and any application requiring a reliable metal-to-metal seal. Always replace crush washers during reassembly to ensure proper sealing—reusing crushed washers can result in leaks and system failure.
