The TURCON® VL SEAL is a single-acting O-ring energized slipper seal that has several advantages over traditional rod seals, including a reduced radial depth allowing for a smaller gland size, tighter leakage control, lower friction from a reduced contact area, and simplicity of design using a standard size O-ring. It features Turcon's Stepseal® 2K back pumping effect and seal geometry that prevents seal roll at low or shuffling pressures. It can operate at pressures up to 5,000 psi with velocities up to 50 ft/s on reciprocating movements from -65°F to +390°F depending on the elastomer material. Standard materials include mineral oil-based hydraulic fluids and others depending
