18mm Alum. Crush Washers 10pk

The FRAGOLA 18mm Aluminum Crush Washers 10-pack provides professional-grade sealing solutions for hydraulic and pneumatic line connections where reliable, reusable compression fittings are essential. Crush washers are precision-engineered aluminum discs designed to create a metal-to-metal seal when compressed between fitting faces, eliminating the need for thread sealant tape and reducing the risk of leakage at critical pressure points. This 10-pack of 18mm ID crush washers delivers the redundancy and cost-effectiveness that field technicians and maintenance professionals demand.

Each washer in this set is manufactured from natural aluminum, a material selected for its balance of malleability and durability. The 18mm inner diameter specification matches standard SAE and metric hydraulic fitting interfaces, ensuring compatibility across a wide range of industrial equipment, mobile machinery, and high-pressure applications. Aluminum crush washers excel in both positive and negative pressure environments, making them suitable for fuel systems, brake lines, cooling circuits, and transmission cooler connections. The ability to reuse these washers multiple times—depending on reuse protocols and system specifications—provides practical economy for shops managing inventory and recurring maintenance cycles.

This product is engineered for technicians, fleet maintenance departments, hydraulic service centers, and equipment repair facilities that prioritize leak-free connections in pressurized systems. Technicians working with heavy equipment, agriculture machinery, construction vehicles, and industrial hydraulic assemblies rely on crush washers as a failsafe sealing method. The 10-pack quantity supports the needs of a typical service call or maintenance program without requiring bulk inventory. Having multiple washers on hand eliminates downtime waiting for replacement parts and provides buffer stock for multi-point fitting applications.

FRAGOLA is recognized in the automotive and hydraulic aftermarket for consistent manufacturing standards and compatibility across OEM and performance system applications. Selecting OEM-compatible crush washers—rather than generic alternatives—reduces the risk of fitting degradation and system contamination.
