Whether you're working in aerospace, automotive, industrial automation, or medical devices, our custom tube adapters ensure secure, leak-proof connections and exceptional durability.

✔ What is a Tube Adapter?

A tube adapter is a mechanical component that connects tubing systems of different diameters, threads, or materials. These adapters allow for efficient fluid or gas transfer between various types of tubes, pipes, or hoses—supporting both metric and imperial standards.

They are commonly used to:

• Connect tubing to valves, manifolds, or pumps

• Transition between different thread types (e.g., NPT to BSP)

• Adapt different tube sizes or wall thicknesses

• Provide disconnection points for maintenance or upgrades
