Our PTFE shoulder washers are designed for electrical insulation, spacing, positioning, and mechanical isolation in demanding assemblies. Manufactured from high-quality polytetrafluoroethylene (PTFE), they provide excellent dielectric properties, chemical resistance, low friction, and reliable performance across a wide temperature range.
The integrated shoulder helps isolate bolts, screws, or other fasteners from surrounding components while providing controlled spacing and alignment.
Key Features
Excellent Electrical Insulation:
PTFE provides excellent dielectric properties for electrical and electronic assemblies requiring reliable isolation between conductive components.
Excellent Chemical Resistance:
Resistant to most acids, alkalis, solvents, and aggressive chemicals, making the washers suitable for chemically demanding environments.
Wide Temperature Stability:
PTFE maintains stable material properties across a broad temperature range for both low- and high-temperature applications.
Low Friction & Non-Stick Surface:
The naturally low coefficient of friction and low surface energy help reduce adhesion and wear between mating components.
Integrated Shoulder Design:
The shoulder provides additional insulation, spacing, alignment, and protection around fasteners and mounting holes.
Precision Dimensions:
Inner diameter, outer diameter, shoulder diameter, shoulder height, and overall thickness can be machined according to specific assembly requirements.
Custom Sizes Available:
Standard and custom dimensions can be manufactured according to customer drawings or OEM specifications.
