Abstract

An insertion tool may be utilized for placement of a seal into a groove of a component. The insertion tool may comprise a base and a seal lifting portion. The seal lifting portion may comprise a surface configured to selectably engage with a seal to move the seal between a lifted position and an unlifted position within an associated groove of a component. The surface of the seal lifting portion may be configured to continuously move the seal between the lifted position and unlifted position. The seal may have a first height h1 and a second height h2, wherein h2 may be less than h1. The seal may be stretched to h2 in the lifted position and returned to h1 in the unlifted positioned in the associated groove of the component.

Dependent claims

An insertion tool comprising:

a base;
an arm comprising a first end and a second end;
and
a seal lifting portion comprising a surface configured to selectably engage with a seal to move the seal between a lifted position and an unlifted position within an associated groove of a component,
wherein the seal has a first height h1 and a second height h2 when engaged with the seal lifting portion and the associated groove of the component, h2 being less than h1, the seal being stretched such that the height of the seal is reduced to h2 in the lifted position, the seal being returned to h1 in the unlifted position in the associated groove of the component,
wherein the second end of the arm is operably connected proximate a first end of the seal lifting portion, and
wherein the seal lifting portion is situated between the base and the arm, the base and the arm configured to maintain placement of the seal against at least a portion of the surface of the seal lifting portion.
