Precision Ring Gapping for Maximum Performance

Modern performance engines—especially those utilizing forced induction, nitrous oxide, or high-compression setups—require custom-tailored piston ring end-gaps. Total Seal Piston Ring Filers are the industry standard for achieving perfectly square, highly accurate ring gaps. LN Engineering offers both Motorized and Hand-Cranked variations to suit the workflow and volume of any engine building facility.

Total Seal’s Hand-Cranked Filers are perfect for builders who demand meticulous, tactile control over the material removal process. For high-volume shops, Motorized Piston Ring Filers are a game-changer. Featuring integrated dial indicators and powered grinding wheels, they allow you to remove material rapidly while ensuring a flawlessly square cut on the ring ends.

Key Benefits for Engine Builders:

• Prevents Ring Binding: Properly gapped and filed rings will safely expand under extreme combustion temperatures without butting ends and scuffing the cylinder walls.
• Perfectly Square Cuts: Engineered to hold the ring at the exact required angle, preventing angled cuts that can lead to ring flutter or blow-by.
• Dial Indicator Accuracy (Motorized): Allows builders to visually track exactly how much material is being removed down to the thousandth of an inch.
