Specifications
The Hallite EXF is a dual-action, double O-ring energized rod cleaner designed to include two unique and distinct cleaning geometries. The two lips combine to scrape debris from the rod and contain residual oil in the rod extension, as well as allow oil to return to the cylinder. O-ring energizers provide the necessary force to maintain the engagement of the wiper lips against the sliding surface and allow the wiper to adjust for deflection.
Generally made from proprietary Hallite Armorlene® materials, this seal is capable of high-speed applications and eliminates any possibility of slippage. High-performance Armorlene® materials, such as HLX, provide excellent wear and scuffing capability, as well as wide temperature range and media compatibility.
The Halite EXF works well in combination with rod seals that support the required dynamic pressure pumping, such as the Hallite R16 rod seal. When combined, they produce a sealing system capable of handling higher speeds, a wide range of fluid compatibilities and a range of service temperatures. For other rod seal arrangements with EXF, it is necessary to ensure that the rod seal provides adequate back pumping pressure or, alternatively, vents the system. Although it is easier to install in the groove, care must be taken not to install it backwards and to ensure proper fit of the three individual components.
