Description
Overview:
The 75mm Diameter Piston Ring Compressor - 2 Band is a compact, workshop-grade tool for installing pistons into engine cylinders cleanly and without damage. Manufactured by Sealey (MPN: VS156), it uses an oil-tempered spring steel band for strength, resilience, and long service life. The two-band design and thumb-operated ratchet mechanism give controlled, even compression of the rings, helping them slide into the bore without snagging. A steel tensioning key is included for quick adjustment. With a 75mm depth (approx. 2.95"), it suits a wide range of piston heights found in cars, light commercial vehicles, motorcycles, stationary engines, generators, and small plant or garden machinery. It accommodates ring diameters from 53mm to 175mm; imperial guidance is 2" to 4" (approx. 51mm to 102mm).
Key Features:
- Durable oil-tempered spring steel band resists fatigue and maintains clamping force over repeated use.
- Thumb-operated ratchet tensioner for precise, progressive compression and better control during fitting.
- Supplied steel tensioning key for fast tightening and release in the workshop or on-site.
- 2-band configuration provides firm, even clamping around the piston circumference.
- 75mm depth (approx. 2.95") suits common piston heights across automotive and small engine applications.
- Covers ring diameters from 53mm to 175mm for broad compatibility across engine sizes.
- Imperial guidance: 2" to 4" (approx. 51mm to 102mm) for users working in imperial measurements.
- Smooth inner surface helps reduce ring scratching and bore entry resistance.
- Compact, portable form factor that fits readily in a toolbox or cart.
- Corrosion-resistant finish for dependable performance in oily, workshop environments.
Typical Applications:
