I.D. and Lever Leak Testing Coupler

High-Performance Internal Sealing Solution | Up to 40 Bar | Air Grip India

At Air Grip India, we specialize in designing and manufacturing advanced leak testing solutions that enhance productivity, accuracy, and safety. Our I.D. and Lever Leak Testing Coupler is specifically engineered to provide a fast, secure, and leak-free connection for internal diameter (I.D.) based testing.

This innovative coupler is ideal for testing pipes, tubes, castings, and machined components—especially where external sealing is not feasible. With a user-friendly lever mechanism, this tool enables operators to quickly connect and disconnect without using any tools, while maintaining a tight and repeatable seal.

What is an I.D. and Lever Leak Testing Coupler?

An I.D. Leak Testing Coupler seals the internal bore of a component, allowing leak tests to be performed efficiently from the inside out. The lever-operated design ensures high-speed manual clamping with minimal effort, offering safety and consistency during pressurization.

It is ideal for pressure decay, bubble, vacuum, or helium leak tests, and is used across a wide range of industrial applications including automotive, refrigeration, HVAC, hydraulic systems, and aerospace.

Key Features

  • ✅ Quick Lever Action
    Tool-free, fast clamping for quick operation and minimal downtime.

  • ✅ Internal Diameter (I.D.) Sealing
    Perfect for components with hard-to-access or sealed external surfaces.

  • ✅ Supports High Pressure Testing
    Designed to handle leak testing pressures up to 40 bar (580 psi).

  • ✅ Durable and Rugged Build
    Manufactured using stainless steel, aluminum, or brass for long service life.

  • ✅ Custom Sealing Materials
    Available in NBR, Viton, EPDM, or Silicone for compatibility with different fluids and gases.

  • ✅ Secure and Repeatable Seal
