H2O Jet's upgraded hydraulic piston! Bands, seals, guides included and already installed. Drop-in-place replacement for the older, 2-ring style. This upgrade with 3-bands provides more contact for greater stability resulting in longer life. The stability also helps the high-pressure seals last longer.
Be sure to install this low-pressure piston (the "biscuit") into the cylinder using either the insert tool or piston ring clamp.
