Quick Connector
In the process of air tightness testing, quickly and reliably sealing pipe fittings or threaded interfaces is a critical factor affecting test efficiency and accuracy. The AMT Quick Seal Connector is specifically designed to solve this problem, offering manual/pneumatic, internal expansion/ external grip, and other models to achieve “second‑level” sealing connections, helping you move away from tedious tape wrapping or welding sealing. The AMT Quick Seal Connector is a professional tool for rapid sealing of pipe ends and threaded ports. By compressing the sealing material to fit tightly against the surface or end face of the test piece, it creates an instantaneous and reliable sealing interface – significantly improving efficiency and consistency in both production line batch testing and laboratory single‑piece tests.
Main parameters
| Type | Actuation | Sealing Principle | Application |
|---|---|---|---|
| Internal expansion | Manual / Pneumatic | Seal expands from inside outward, pressing against inner wall of tube | Sealing of round, square, or shaped tube inner diameters |
| External grip | Manual / Pneumatic | Seal contracts from outside inward, gripping the outer wall of tube | Sealing of smooth tubes, raised tubes, or hoses outer diameters |
| Face seal | Manual / Pneumatic | Seal compresses axially against the end face of thread | Threaded ports, flange faces, irregular ports |
Technical Advantage
Quick Connection – Second‑Level Operation
Single‑handed push/pull or pneumatic button completes connection/disconnection – no tools required, greatly reducing workpiece clamping time.
Reliable Sealing – Leak‑Free
Made of oil‑resistant, wear‑resistant high‑quality sealing materials with precisely calculated compression ratio, ensuring zero leakage within the test pressure range.
Strong Adaptability – One Connector, Multiple Uses
The same connector can be adapted to different pipe diameters or thread sizes by changing sealing rings or jaws, reducing the number of fixtures needed.
No Surface Damage
The sealing contact surface is made of non‑metallic elastic material, which does not scratch the pipe wall or threads – ideal for precision component testing.
Customization Supported
For extra‑long pipes, tapered pipes, very small diameters, or special interfaces, non‑standard custom seal connectors are available to meet various requirements.
Actuation Options
Manual type: No air supply needed; mechanical locking via handle or knob – suitable for mobile scenarios such as on‑site maintenance and spot checks.
Pneumatic type: Seal expansion/contraction driven by cylinder – can be integrated into automated production lines for unmanned operation.
Typical Applications
Air tightness testing of automotive air conditioning lines, fuel lines, brake lines
Sealing of new energy battery pack cooling lines
Leak testing of copper/aluminum tubes in home appliances (refrigerators, air conditioners)
Water/gas circuit sealing for gas water heaters and wall‑hung boilers
Testing of medical device tubing and filter ports
Any application requiring temporary sealing of pipe ends or threaded ports
Selection Guide
Determine the port type: round tube? thread? flange?
Measure the port size: inner diameter or outer diameter, and tolerance range.
Choose sealing method: internal expansion (inner diameter) or external grip (outer diameter) or face seal.
Choose actuation: manual (flexibility) or pneumatic (automation).
Specify the test pressure – ensure the connector’s rated pressure meets the requirement.
Connect one second faster, test ten times more accurately.
