The garter spring in a lip seal is used to

Explanation:
The garter spring provides preload to the sealing lip, pushing it against the shaft so the lip maintains firm contact as shaft runout, wear, or pressure changes occur. That constant radial force creates a better, more reliable seal by keeping the lip pressed against the surface, which helps prevent leakage. It isn’t about reducing friction or improving heat transfer—the spring’s primary job is to increase and sustain the sealing pressure on the rotating shaft.
