• Consistent compression and fit with a Durometer 55A hardness, providing an optimal balance of flexibility and sealing force.
• Precise dimensional compatibility with a 0.17" ID and 0.375" OD, designed specifically for a secure fit on No. 10 screws.
• Full regulatory compliance with RoHS 3 and REACH, making them safe for use in global industrial supply chains.
• Enhanced assembly longevity through material durability, resisting degradation from oils, weathering, and compression set.

Professional Applications & Engineering Value

This neoprene rubber flat washer is engineered to solve critical challenges in industrial assembly, such as sealing against moisture and dampening vibrations in automotive, electrical enclosures, and outdoor equipment. The Durometer 55A material offers the ideal hardness to compress uniformly under fastener torque, creating a reliable seal without over-stressing the No. 10 screw or the mating surface. Its black color and robust composition provide consistent performance in applications exposed to oils and varying weather conditions. By specifying this inch-system washer, engineers can enhance product reliability, reduce maintenance cycles, and ensure compliance with international environmental standards like RoHS and REACH.

Specification Summary & Compliance

This flat washer features an Inside Diameter (ID) of 0.17", Outside Diameter (OD) of 0.375", and a Thickness range of 0.078-0.108", ensuring precise fit for No. 10 screw size applications. Manufactured from neoprene rubber with a hardness of Durometer 55A, it complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its suitability for use in environmentally conscious and globally restricted substance-controlled industries.
