EPDM Composite Sealing Washers With 304 / 316L Stainless Steel And Weather Resistant EPDM For Photovoltaic Mounting Systems
This comprehensive range of waterproof composite sealing washers includes stainless-EPDM bonded washers, pure EPDM single gaskets, transparent PVC washers, and wind-proof combined washers. The metal components utilize 304/316L stainless steel, rubber parts are manufactured from weather-resistant EPDM, and the transparent variants feature durable PVC material.
These advanced composite washers combine the mechanical strength of metal with the superior sealing properties of rubber, delivering exceptional waterproofing, dust-proofing, shock absorption, and anti-aging performance. They are extensively used in photovoltaic mounting systems, curtain wall fasteners, color-steel roof connections, and various outdoor installations to prevent rainwater penetration into joint gaps.
Available in sizes ranging from 4.2-9.5 with common bore sizes of 4.8, 5.5, and 6.3, these washers serve as essential auxiliary fastening accessories for outdoor construction and solar energy projects.
