PEEK Compression Spring

SKU: PKCS10208
Download Data Sheet
$24.83 inc. VAT

These springs are engineered for repeat compression cycles in applications requiring exceptional strength, thermal stability and chemical resistance. Unlike metallic springs, the nature of their PEEK properties prevents corrosion, contamination, or electrical conductivity concerns.

Their superior wear resistance, low moisture absorption, and broad chemical compatibility ensure dependable long-term performance across a wide range of industrial, medical, aerospace, and semiconductor applications.
