Dimension Overview:

Quality Assurance & Testing 

To guarantee long-term durability and secure performance under repeated use, LINKHIVE applies rigorous quality control and validation tests to every B Series seal connector

Push pull seal connector  Quality Control Procedures

• 100% Visual & Dimensional Inspection
  Every medical connector  is checked for surface defects, plating consistency, and dimensional accuracy (keying, shell, contacts).

• Keying & Mating Precision
  Each shell undergoes tolerance inspection to ensure accurate alignment with multi-keying codes (G, A, B...).

• Material Certification
  Shells made of chrome-plated brass; inserts made from PPS/PBT/PEEK are verified for thermal and dielectric stability.

      metal circular connector  Electrical Testing

• Contact resistance: ≤6.5 mΩ

• Insulation resistance: ≥5000 MΩ (600V DC)

• Dielectric withstand voltage:

• 1450V between contacts

• 1000V between contact and shell
