Help with this design
I took a guess as to the model you are trying to duplicate from the Design model in your Practice model. There are a number of differences in size but I will leave that up to you to change. The video will show the process I used, others may do it differently. Model attached.

Thanks so much for your help. For this model that was already in the file
How to make it from the model you help me with. I want also the O ring groove to be 46.128mm ID and 51.872mm OD. Thanks again so much
Edit: Please verify the O-Ring diameter is 2.872 mm and the center line diameter is 49 mm.

I did not get a confirmation from you as to the O-Ring size but I went ahead and used an O-Ring with a cross-section diameter of 2.872 mm and a center diameter of 49 mm. I have modeled it and added it to the other model to show its location. I removed the "tear-drop" o-ring groove and set it in the model so it is center in the o-ring groove. I saw no purpose in the extra depth in the groove. If this is not right simply edit the first sketch in the timeline to your liking. Model is attached.

You new O-Ring dimensions fall inside the existing model walls. Are you sure about these dimensions? They are a far cry from what you gave me in Message #4. If correct, do I move the wall in to accommodate and if so, what about the inside curve below the wall (7 mm dia.)?

This may or may not be relevant for your application, But O-ring Grooves should be Square not round.
Refer to the parker O-ring guide for how to correctly design O-ring grooves for various applications

You probably want to look at Section 4 for Static Seals
The Handbook has the correct Groove Dimensions for Each O-ring size too

I did not understand what you mean but the original design in the attachment (design) and my file I work in to practice this design I want it the same as this worked for me already well and I want just a last help to make this design. I am still beginner and hope you make it simple by video all details of the design is in the file and I attached it again and I want your help and hope you help me. I tried to cut the edges so I make it the same model as this
but i could not connect all bodies together sorry i am new in this. Another issue i found is that the O ring sizes are not the same It should be 51.872 OD and 46.128 as described in the model. I attached the model again with my recent practice with you. Thanks
I did the video you requested using the model I attached to Message #6.
