Federal-Mogul Powertrain’s one-piece, rubber-to-metal bonded piston is designed to activate the clutch brake band. It features a compact, one-piece design that:

• Eliminates potential leak paths
• Simplifies assembly
• Improves reliability

The piston can be supplied as a single-piece hydraulic component or as part of a fully assembled piston module with return springs and cap, reducing the need for multiple-component supply and assembly.

Our Unipiston^® replaced the multi-component pistons and seals used in automatic transmission units with a single-piece bonded, sealed piston, delivering more reliable performance with lower in-place cost.

The single-piece construction simplifies assembly and reduces potential leak paths.
