The HJ-4 is a metal connector set that creates a three-pipe intersection on two axes. This connector is the best option when you need to create separations without damaging the structural rigidity of some pipes. The HJ-4 is the last of the four most used Flexpipe joints.

To create an HJ-4, you need to regroup two H-4 together with two M6-25B bolts and two M6-N nuts. Because this connector is the last one with standard application in a majority of structures, you should keep the parts necessary for it. The HJ-4 will be used mainly in the center of exterior sides. This connector will give you the option of making a pipe grid with fewer tubes than would be required with a wire mesh, which is made with HJ-7 connectors. This HJ-4 will also be ideal when you need to create an intersection between two perpendicular pipes, but you don't want to weaken the strength of a long tube or a series of long tubes. The joint also allows you to secure a stamp wheel easily at the bottom center of the structure.

This connector is one of the easiest to connect along with the HJ-1. The HJ-4 is equipped with twelve striations for grip and six reinforcement holes for the construction of heavy-duty and structures and protection against frequent vibration. The HJ-4 is compatible with most 28mm pipe systems and equivalent joints. Don't forget to select the ESD version called HJ-4NP for all you antistatic applications.

1- Make sure you have the following parts:
2 H-4
2 M6-25B
2 M6-N
3 28mm pipes of your choice
1 Allen key or one drill equipped with an Allen Key 5mm tip
2- Take two connectors H-4 and group them around the P1 pipe.
3-Take two M6-25B bolts and two M6-N nuts and insert them into the corresponding openings. Make sure to put the bolts on the more accessible side.
4- Tighten the M6-25B bolts and nuts M6-N together a few threads , but no more." 5- Insert the P2 and P3 pipes within the HJ-4 between the first and second guides as shown in the plan .
6- Tighten completely the M6-25B bolts and M6-N nuts together until the HJ-4 attached firmly to the three pipes . A force of 9.8 Nm is recommended for this step.
