RS PRO Vulcanised Fibre Washers M6 Red RoHS 12.5mm OD 6.4mm ID 0.8mm Thickness 526-388

RS PRO 526-388 Vulcanised Fibre Washers are precision-engineered components designed for reliable sealing and insulation in a wide range of industrial applications. With an M6 compatible hole diameter, 12.5 mm external diameter, and 0.8 mm thickness, these washers provide secure spacing and leak prevention in fastener assemblies. Manufactured from hard red vulcanised fibre, they deliver excellent resistance to sea water corrosion, petroleum derivatives, oils, organic solvents, abrasion, and UV exposure, making them suitable for demanding operational environments.

These fibre washers are commonly used to distribute load, mitigate uneven surfaces, and enhance fastening reliability, especially where insulation or sealing is crucial. Applications include electrical insulation, plumbing, automotive assembly, marine engineering, glazing, and lighting installations. Their RoHS-compliant material ensures adherence to environmental standards.

The washers are available in M6 sizing and are suitable for both ISO metric and BA fasteners, offering versatility across industrial, laboratory, and construction settings. Deploy these washers where space constraints exist and insulation or sealing performance is required.

The vulcanised fibre material provides electrical insulation and is resistant to most industrial fluids, extending the lifespan of the installation and reducing maintenance. Washers minimize leakage and contamination, playing a key role in plumbing and marine environments, and also prevent metal-to-metal contact in electrical assemblies.

Features include abrasion and UV resistance, making them ideal for outdoor and exposed applications. Their red coloration aids identification during installation. Packaged for easy integration into manufacturing or maintenance operations.
