The Hallite SRB is a single-acting, low-friction rod buffer seal, designed to be utilized in conjunction with a primary pressure seal. The buffer is designed from proprietary Armorlene® material face ring paired with a specially profiled energizer and an integrated anti-extrusion ring. The Armorlene® face ring offers low friction and the elimination of stick-slip. High-performance Armorlene® materials, like HLX, provide outstanding wear and extrusion-resistance properties as well as large range of temperature and media compatibility. The SRB is a pressure buffer seal that protects the primary rod seal from high-frequency pressure spikes in a system. The design allows oil to pass through to the rod seal while holding back pressure spikes. The Hallite SRB also allows pressure to pass back into the system, preventing a pressure trap situation between the rod seal and the buffer seal. The SRB is an excellent pressure buffer option in heavy-duty applications, offering extended sealing system life and performance.
