Product Description
Essentra 543-743 is an industrial-grade hex polyvinyl chloride spacer designed to provide accurate component separation and reliable mounting in various mechanical and electronic assemblies. With a 25.4 mm length, this spacer supports precise alignment of parts, ensuring structural integrity and consistent performance in high-volume production environments and specialist builds.
Constructed from polyvinyl chloride (PVC), the spacer offers robust chemical resistance, excellent insulation properties, and resilience against environmental stress, making it ideal for demanding industrial applications. Its hex shape facilitates secure installation and compatibility with hex socket support structures. The 2.8 mm inside diameter conveniently accommodates self-tapping screws, machine screws, and studding, enabling versatile mounting solutions across assembly lines, enclosure builds, PCB designs, and control panels.
The plain finish provides a smooth surface that reduces friction during installation and minimizes wear, supporting long-term use in repetitive operations. The hex size across flats of 6.4 mm ensures a firm and stable fit, preventing rotation and enhancing assembly reliability.
Industrial use cases include PCB insulation, panel standoffs, mechanical spacing in circuit production, and application in machinery requiring electrical insulation and corrosion resistance. The grey PVC type is specifically noted for compatibility with No.6 self-tapping screws, expanding its relevance in PCB and electronics design.
