The first end cap, the first deformable element, the first insert, the third deformable element, the second insert, the second deformable element, and the second end cap together can form a body having a bore extending therethrough. The first deformable element, the second deformable element, and the third deformable element can have a compressive strength that is less than a compressive strength of the first and second inserts.
