This round nylon spacer is designed for reliable spacing and insulation in a wide range of applications. Manufactured from black 25% glass‑fibre reinforced polyamide (PA), it offers excellent mechanical strength, durability and dimensional stability. With an outer diameter of 8 mm, an inner diameter of 4.2 mm to suit M4 fixings, and an overall length of 15 mm, it is ideal where precise separation and alignment are required. The material meets UL94 HB flammability rating, making it suitable for use in demanding environments where basic flame resistance is necessary. Commonly used in medical equipment, test and measurement devices, automotive electronics, sensing and instrumentation systems, alternative energy installations and general industrial assemblies, this spacer provides secure, consistent spacing between components while helping to prevent short circuits and mechanical contact. Its moulded cut‑end design ensures a good fit, easy installation and long‑term performance in both small‑scale projects and professional production builds.
