A cylinder liner seal includes an annular seal body defining a seal center axis, a first seal surface, and a second seal surface positioned opposite to the first seal surface. The first seal surface is contoured to form a first plurality of seal beads extending circumferentially around the seal center axis, and the second seal surface is contoured to form a second plurality of seal beads extending circumferentially around the seal center axis. Each of the first plurality of seal beads and the second plurality of seal beads define a plurality of peaks alternating with a plurality of troughs together forming a sinusoidal profile. A cylinder liner assembly and methodology of making the same are also disclosed.

Seal for cylinder liner assembly and method for making the same

An integrated seal member includes an at least partially annular body defining a longitudinal axis, a radial direction, and a circumferential direction. The at least partially annular body includes a top annular mounting portion, a sealing portion including at least one top sealing feature and at least one bottom sealing feature, and a connecting portion that extends at least radially outwardly from the top annular mounting portion to the sealing portion.

Integral filter endcap, mold, and seal

A funnel or drain back seal and systems, assemblies, components, kits, and methods thereof can comprise a body defining an opening that extends from a top of the body to a bottom of the body; a head portion that extends outward from the top of the body; and a flap or lip that extends outward from the bottom of the body. The opening can be adapted to pass draining oil from the top of the body to the bottom of the body for supply into an engine block.

Oil drain back seal and systems, assemblies, kits, and methods thereof

An integrated seal member includes an at least partially annular body defining a longitudinal axis, a radial direction, and a circumferential direction. The at least partially annular body includes a mounting portion, a sealing portion including at least one top sealing feature and at least one bottom sealing feature, and an apertured connecting portion that extends radially outwardly from the mounting portion to the sealing portion.
