Steel Washers PP8 – Reliability in E90 Systems

PP8 washers are a key mounting element in E90 maintenance systems, ensuring stable and secure connections. The package contains 100 pieces, making them an ideal choice for both professional installers and larger projects. Made of steel and protected with galvanized coating, they guarantee corrosion resistance and long-term operation.

Application and Design Features

These washers with an outer diameter of 16 mm and an inner diameter of 8 mm are designed for metric screws size 8. Their round hole ensures a precise fit, and the material – steel – provides mechanical strength. Galvanized coating is a standard protection against corrosion, especially important in installations exposed to moisture or changing weather conditions. These washers comply with DIN 125 standard, confirming their quality and dimensions.

Safety and E90 Certification

The E90 maintenance system, in which these washers are used, is critical for building safety. The E90 designation guarantees that the installation elements (fire alarm, fire alerting, emergency lighting) will maintain their functionality for at least 90 minutes in the event of a fire. By choosing PP8 washers, you are investing in the reliability and safety of the entire system. This ensures that the installation meets the required standards and provides protection in emergency situations.
