The Air-Tightness Testing Device for Automotive Connectors is designed to perform non-destructive airtightness tests on components of various shapes. Using precise positive and negative pressure control, it evaluates seals and connector integrity under controlled conditions. This device is widely applicable across automotive and industrial sectors, including engine casings, oil pumps, pipelines, valves, airbags, battery casings, and rubber hoses, ensuring compliance with quality and safety standards.
Application
This testing device is suitable for:
(1) Evaluating the airtightness of automotive connectors, pipelines, and seals.
(2) Testing engine casings, compressors, oil pumps, and water tanks for leak prevention.
(3) Assessing airtight performance of airbags, sealed workrooms, and industrial enclosures.
(4) Supporting R&D, quality control, and compliance verification in automotive and industrial manufacturing.
Standards
(1) ISO 6722 – Road vehicles: Electrical cables – Dimensions and test methods.
(2) ISO 14572 – Road vehicles: Test methods for connector sealing performance.
