S-95611A275 0.5" ID x 1.125" OD Plastic Washers

Key Features & Benefits at a Glance

• Superior chemical resistance from PVC plastic construction, ideal for harsh industrial environments where metal washers would corrode
• Excellent electrical insulation properties for safe use in electrical assemblies and applications requiring non-conductive components
• Maintains structural integrity with Durometer 65D hardness, providing reliable load distribution without cracking or deforming under pressure
• Wide temperature tolerance up to 140°F, ensuring consistent performance in various operating conditions
• Precise dimensional fit with 0.5" ID and 1.125" OD, creating secure fastening for 7/16" screws with minimal movement
• Regulatory compliance assurance with RoHS 3 and REACH standards, meeting international environmental and safety requirements
• Reduced maintenance needs thanks to PVC's inherent durability and resistance to degradation from moisture and chemicals

Professional Applications & Engineering Value

These PVC plastic flat washers deliver exceptional engineering value in applications where chemical resistance and electrical insulation are critical. The gray PVC material provides excellent protection against corrosive substances, acids, and alkalis that would rapidly degrade metal washers. With a Durometer 65D hardness rating, these washers maintain their structural integrity while distributing load evenly across surfaces, preventing damage to connected materials. The 0.5" ID ensures precise fitting for 7/16" screw size applications, while the 1.125" OD provides ample bearing surface. These industrial plastic washers are particularly valuable in chemical processing equipment, water treatment facilities, electrical enclosures, and marine applications where non-corrosive, non-conductive fastening solutions are essential for long-term reliability and safety.

Specification Summary & Compliance

This flat washer features precise inch system dimensions with 0.5" internal diameter, 1.125" outer diameter, and thickness ranging from 0.053" to 0.071". Manufactured from PVC plastic with Durometer 65D hardness, it accommodates 7/16" screw size applications. The washer maintains performance in temperatures up to 140°F and complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and restricted substance compliance for industrial use worldwide.
