M3 - Red Fibre Washers , 6.4mm OD , 0.6mm Thickness - Red | Vital Parts - WASH-31-64-6-FIBRE-R

Our Red Fibre Washers are a specialist sealing solution used to provide watertight, non-conductive protection in electrical, plumbing, and automotive applications. Designed for environments where vibration, fluid exposure, or electrical insulation is a concern, these washers deliver dependable performance where it counts.

This product has a wide temperature resistance (-60°C to +100°C), is non-conductive, lightweight, and naturally swellable to improve sealing performance. These properties make it an excellent option for leak prevention and component insulation.

What are Red Fibre Washers?

Red Fibre Washers are flat sealing discs made from vulcanised fibre - a material composed of chemically treated cellulose (typically derived from cotton or wood pulp). This heat-treated, high-strength material expands slightly when exposed to moisture, helping the washer form a secure, watertight seal. The red pigmentation comes from iron oxide used during manufacturing, giving the washers their distinctive colour (note: shade may vary but has no effect on performance).
