PVC Transparent Plastic Insulating Flat Washer Gasket Spacer Ring M1.6–M12

PVC Transparent Plastic Insulating Flat Washer Gasket Spacer Ring M1.6–M12

Transparent PVC plastic insulating flat washers for electrical isolation, PCB assembly, and precision mechanical spacing. The non-conductive PVC material prevents galvanic corrosion between dissimilar metals and provides electrical isolation between fasteners and sensitive PCB components. Transparent color allows visual inspection of the assembly.

Key Specifications

Why Choose PVC Insulating Washers?

• Electrical isolation — prevents current flow between fastener and PCB or chassis; protects sensitive components
• Transparent PVC — allows visual inspection of assembly; clean, professional appearance
• Galvanic corrosion prevention — isolates dissimilar metals (e.g., steel screw on aluminium chassis)
• Wide size range — M1.6 to M12 covers all standard electronics and mechanical assembly sizes
• Lightweight — minimal weight addition to PCB and electronics assemblies

Typical Applications

• PCB mounting isolation (between screw head and PCB surface)
• Electronics enclosure assembly (isolating steel screws from aluminium panels)
• Precision instrument and sensor mounting
• Battery terminal isolation and insulation
• General mechanical assembly requiring electrical isolation
• 3D printer frame and electronics assembly

Compatible With

M1.6, M2, M2.5, M3, M4, M5, M6, M8, M10, M12 metric screws and bolts. Compatible with DIN125 flat washer dimensions. Suitable for use with: PCB mounting screws, electronics enclosure fasteners, and general metric fasteners requiring electrical isolation.

FAQ

Q: What is the voltage rating of PVC insulating washers?
A: PVC has a dielectric strength of approximately 15–20 kV/mm. For standard electronics applications (up to 48V DC), PVC insulating washers provide adequate isolation. For high-voltage applications, use PTFE or nylon washers with higher dielectric ratings.

Q: Can I use these outdoors?
A: PVC has moderate UV resistance and is suitable for short-term outdoor use. For long-term outdoor applications, nylon or PTFE washers are more UV-stable.
