3" PISTON RING COMPRESSOR RATCHET (VEH23970)

The 3" Piston Ring Compressor Ratchet (53-175mm, #PF3203) is a specialty automotive service tool engineered to safely compress piston rings for seamless installation into the engine cylinder bore.

Key Features & Design

Double-Band Friction Mechanism: Built with a heavy-duty spring steel band that exerts equal pressure across the entire piston ring surface, preventing twisting, overlapping, or breakage during assembly.

Versatile Range: Features an adjustable capacity spanning 53mm to 175mm (2-1/8" to 7"), making it compatible with a wide array of passenger vehicles, small trucks, motorcycles, and small engines.

Positive Locking Ratchet: Equipped with a dependable ratcheting mechanism that holds the band securely at the desired diameter, paired with a quick thumb-release lever for rapid removal once the piston is seated.

3-Inch Band Height: The 75mm (3-inch) height provides full, even coverage over standard multi-ring piston configurations, stabilizing the assembly against the engine block.

Durable Construction: Crafted from high-tensile, heat-treated steel to resist workshop wear and maintain proper tension over extended use.
