Professional Applications & Engineering Value

These wool felt flat washers deliver critical engineering solutions where conventional metal washers fall short. The natural wool felt material creates an effective barrier against vibration transmission, making them ideal for machinery bases, motor mounts, and precision equipment requiring vibration dampening. Their thermal insulation properties solve temperature-related challenges in HVAC systems, automotive applications, and industrial equipment operating in extreme environments. The gray wool felt construction provides consistent compression recovery and excellent sealing performance in gasketing applications, while the precise 1/4" ID ensures secure fitment on standard fasteners. These washers effectively address common industrial pain points including component wear from vibration, thermal transfer issues, and the need for compliant sealing solutions.

Specification Summary & Compliance

This flat washer features precise inch system dimensions with 0.25" inner diameter, 0.75" outer diameter, and controlled thickness range of 0.230-0.270". The wool felt material maintains consistent performance with Durometer 30A hardness rating. Manufacturing and material compliance includes full adherence to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and global market acceptance for industrial applications requiring reliable thermal and vibration management solutions.
