M5 FKM Washer, 5.3mm ID x 10mm OD x 1mm Thickness, DIN 125A, Black | Vital Parts - WA125-M5-FKM-N
Our M5 FKM Washer is a high-quality flat sealing washer made from FKM, a durable rubber also known by the brand name Viton. With an internal diameter of 5.3mm, an outside diameter of 10mm and a thickness of 1mm, this washer conforms to DIN 125A standards and is presented in a sleek black finish. FKM washers are highly sought after for their outstanding resistance to extreme temperatures, oils, chemicals and environmental conditions, making them the ideal choice for sealing and isolation tasks in demanding industrial applications.
What is an FKM Washer?
An FKM (fluoro rubber) washer is a high-performance sealing component designed to withstand aggressive chemicals, oils, fuels and solvents. It performs exceptionally well in environments with continuous temperatures ranging from -20°C to +200°C, with short-term spikes up to 250°C. Thanks to its low gas permeability and superb compression set resistance, this Viton washer ensures long-lasting performance even under stress, pressure, or prolonged contact with corrosive fluids. Its black colour and DIN 125A specification make it suitable for both functional and aesthetic applications in precision assemblies.
Typical Applications & Key UK Industries
FKM sealing washers are trusted across a variety of high-demand industries throughout the UK. Commonly used in:
- Automotive & Motorsport: Used in engines, gearboxes and fuel systems to resist oil and fuel degradation.
- Petrochemical & Oil Refining: For sealing joints exposed to hydrocarbons and aggressive solvents.
- Aerospace & Defence: Specified for high-temperature, chemically volatile environments in aircraft systems.
- Pharmaceutical & Food Processing: Selected for hygiene-critical applications thanks to chemical resistance and compliance potential.
- Marine & Offshore: Ideal for sealing components exposed to saltwater, lubricants and wide temperature ranges.
