Detailed Description

Sealed Power E-970K is an engine piston ring set engineered for standard-bore 89.00 mm cylinders. The ring package uses a chrome steel top ring for wear resistance, a grey iron second ring with phosphate coating for stable sealing characteristics, and a 3-piece flex vent oil ring to help manage oil control in the cylinder wall environment. The barrel-face top ring and reverse torsional second ring are specified to work with 1.20 mm, 1.50 mm, and 3.00 mm groove widths.

What It Helps Fix

• Excessive oil consumption from worn oil control rings
• Low compression caused by ring wear or loss of sealing
• Blow-by from worn piston ring sealing surfaces
• Oil fouling related to tired ring packs
• Compression imbalance during engine rebuild service

Installation Notes and Tips

Verify bore diameter, ring groove widths, and cylinder count before installation. Confirm the 89.00 mm standard-size specification matches the engine block and piston setup, and check ring end gaps according to the engine builder’s service procedure. Clean piston ring grooves thoroughly and inspect cylinder walls for wear or taper before assembly. Professional installation and final measurement are recommended for rebuild accuracy.
