Wiseco RCS06750 Tapered Piston Ring Compressor Sleeve 67.5mm Bore

The Wiseco RCS06750 is a precision-machined tapered piston ring compressor sleeve designed for a 67.5mm (2.657 in.) bore. Built to the same standard as Wiseco's renowned forged pistons, this sleeve is an essential engine-building tool for professional builders and performance enthusiasts alike.

Unlike traditional band-style ring compressors, this tapered sleeve design uniformly guides piston rings into the bore in one smooth, controlled motion — virtually eliminating the risk of bent or broken rings during installation. It is especially effective when working with thin, high-performance oil rings that are notoriously difficult to seat with conventional tools.

Key Features:

• Machined from Wiseco sleeve forgings for exceptional strength and durability
• Hard-anodized and PTFE (Teflon) coated for low friction and long service life
• Smooth tapered radius guides rings evenly into the specific bore size
• Compatible with pistons from any manufacturer — not just Wiseco
• 67.5mm (2.657 in.) bore size — sold individually

Wiseco tapered ring compressor sleeves are available across a wide range of bore sizes from 65.5mm to over 105mm, making it easy to equip your shop with the right tool for every build. The RCS06750 is an indispensable addition to any performance engine assembly toolkit.
