Professional Applications & Engineering Value
These PTFE plastic flat washers deliver critical performance in demanding industrial settings where conventional materials fail. The white PTFE construction offers outstanding chemical resistance against corrosive agents, making them ideal for chemical processing equipment, semiconductor manufacturing, and pharmaceutical applications. Their high-temperature rating of 500°F ensures reliable operation in thermal management systems, oven assemblies, and high-heat machinery. The low friction coefficient prevents sticking and binding in dynamic applications, while the precise 0.25" inner diameter and 1.5" outer diameter provide optimal load distribution for No. 12 screws in electrical enclosures and precision equipment where insulation and thermal stability are paramount.
Specification Summary & Compliance
This flat washer features inch system dimensions with 0.25" inner diameter, 1.5" outer diameter, and thickness ranging from 0.027" to 0.035". Manufactured from PTFE plastic with Durometer 55D hardness, these washers are designed specifically for No. 12 screw applications. The product complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and global market acceptance for industrial and electrical applications requiring high-temperature performance and chemical resistance.
