Hydraulic Piston Assembly; Biscuit - Hi-Load Piston

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. Maintenance Kits:  302013-1 for the 40&60kpsi Intensifiers 392013-1 for the 87,000, 90,000, 94,000 Intensifiers
