Oil-resistant tubing for fuel lines, waterproof sealing for harness branches, and orange HV identification for EV cables. IATF 16949 certified.

Home / Industries / Automotive

Automotive wire harness manufacturers need tubing that passes OEM fluid resistance protocols, installs on high-speed automated lines, and carries the quality certifications their customers audit.

ZZ passed IATF 16949 automotive quality management certification in 2019. Our YRS series tubing has been tested to Honda brake fluid (DOT 3) and 90-octane unleaded gasoline immersion protocols, retaining ≥14 MPa tensile strength after 72-hour exposure.

For EV high-voltage harnesses, our SRS dual-wall series provides sealed insulation with orange color identification per LV 112 requirements.
