Professional Applications & Engineering Value

These SAE wool felt flat washers provide critical engineering solutions where conventional metal washers fall short. The wool felt material with Durometer 20A hardness creates an effective barrier against fluid penetration while absorbing mechanical vibrations that can loosen fasteners over time. The gray felt construction offers consistent density for reliable compression across the entire 0.734" OD surface area. Engineered for industrial applications requiring temperature stability, these SAE J314 compliant washers maintain their sealing integrity from sub-zero conditions to elevated temperatures, preventing leaks in hydraulic systems, machinery enclosures, and automotive assemblies where thermal cycling is common. The 3/8 inch size specification ensures perfect compatibility with standard fasteners while the felt material compensates for surface imperfections that could compromise seal effectiveness.

Specification Summary & Compliance

This flat washer features precise dimensional specifications including 0.406" inner diameter, 0.734" outer diameter, and thickness ranging from 0.055" to 0.069". Manufactured to SAE J314 standards for consistent performance and interchangeability in inch system applications. The product is fully compliant with RoHS 3 (2015/863/EU) regulations and REACH (EC 1907/2006) requirements, including the latest SVHC updates as of June 14, 2023. The wool felt material maintains performance characteristics across the specified temperature range of -80°F to 200°F while providing consistent Durometer 20A hardness for reliable sealing and vibration damping applications.
