GripSeal G72R Quick Seal Coupling: Test Solution for Shaped Nozzles of Automotive Air Conditioning

Automotive thermal management systems, from cooling water tanks to air-conditioning condensers, evaporators, and then to various high and low-pressure pipelines, have always been the focus of attention on the production line. Although the diameter of the pipe fittings has certain standards, the interface shapes vary widely, especially the special-shaped nozzles such as automotive air-conditioning pipelines, which often bring no small challenges to fast connection and airtightness testing.

In response to this long-standing pain point,GripSeallaunchedG72RSeries Quick Seal CouplingIt provides a solution that takes into account both efficiency and adaptability.G72Rsealing jointThe design idea is not to create a universal connector, but to quickly respond to different interface forms by pressing the bayonet scheme.

Design logic: handle drive, grab and test

G72Rsealing jointThe core operation logic of is very simple and direct. Drive the internal claw mechanism by pressing the handle: when the handle is pressed, the claw opens, which can easily fit into the tube mouth under test; release the handle, the claw automatically retracts and grasps the pipe fitting. At this time, the end seal is triggered, and the test medium can be passed. The whole process is completed in one go, which not only reduces the learning cost of the operator, but also avoids the connection reliability problem caused by the difference in techniques.

Model analysis: adapt by "type", not by "size"

Unlike standard round pipe fittings,G72Rsealing jointThe common shaped nozzles are classified into three types of application solutions, and the customer can directly choose the type according to the interface structure of the tested part:

single hole application: For a single nozzle, the maximum test pressure can be reached50barTo meet the high pressure testing requirements of air conditioning pipes and radiators.

Double hole application: For interfaces with two side-by-side holes on the same plane, the connector body can cover two test points to achieve synchronous sealing, with maximum support50barAir pressure test.

Double tube applicationFor two parallel pipelines with a very small center distance, traditional two connectors cannot be used side by side.G72RThe two sealing units are integrated through an integrated body design, which also supports the highest50barThe test pressure.

Materials and craftsmanship: built for long-term stable operation

Considering the high-frequency use environment of the production line and the diversity of test media,G72Rsealing jointThe main body is made of aviation-grade aluminum alloy, which reduces the operating weight while ensuring the structural strength; the core claw is made of stainless steel, which has excellent wear resistance and anti-corrosion ability, which is the reason why it can withstand pressure stably50barHardware guarantee; the sealing ring is made of nitrile rubber by default, which can cover most air tightness test scenarios. At the same time, seals of different materials can be replaced according to the actual contact medium.

For the production line of radiator, condenser or air conditioning pipeline, the value of quick sealing joint is not only to complete the physical connection, but also to reduce the adaptation trouble caused by different interface shapes. Through the clear division of three types of applications, as well as the bayonet and sealing form designed for different nozzles, the operator no longer needs to repeatedly try and error in various joints, and directly select the corresponding model according to the nozzle shape. This isG72RThe core logic of the series is to cover the ever-changing special-shaped nozzles with a clearly classified scheme, making the connection simple, reliable, and predictable.
