There are several techniques for installing seals, depending on the type of seal and the application. Here are some common seal installation techniques:

Press fit: The seal is pressed into place using a hydraulic press or other tool, typically for static seals like O-rings or gaskets.

Stretch fit: Some seals, like V-ring seals, are designed to be stretched over the shaft or housing, and then contract back into place to create a seal.

Adhesive bonding: Some seals, such as lip seals, are bonded to a metal or plastic component using an adhesive.

Shrink fit: Some seals, like heat-shrinkable tubing, are heated and then shrunk to fit tightly around a component.

Mechanical fastening: Some seals, such as gaskets, may be held in place by mechanical fasteners like bolts or clips.

It's important to follow the manufacturer's recommendations and specifications when installing seals, to ensure a proper seal and prevent leaks or other problems.
