The Ring Compressor squeezes rings on the Low-Pressure Piston so it can be inserted into the cylinder without damage to the rings.
Simply open up the clamp, slide it over the biscuit/low pressure piston, tighten it down, and let it sit for a few minutes. When the clamp is removed, the piston assembly should slide into the cylinder without catching on the rings. Result will be an installed piston without any damage to the rings to provide unprecedented, long, stable performance!
Ideal for use with the Hi-Load Piston, H2O Jet's hydraulic piston.
