The Hallite PFR is a chamfered, double-acting piston seal that performs well in both high- and low-pressure systems. The PFR has chamfers on the primary sealing face paired with either a square or an o-ring elastomer energizer. Typically, the square energizer is preferred for heavy-duty applications, as it provides superior interference and stability in the groove. High-performance Armorlene® materials, like HLX, provide outstanding wear and extrusion-resistance properties as well as large range of temperature and media compatibility. Hallite’s PFR seal is well-suited for a variety of hydraulic and pneumatic reciprocating applications. Hallite recommends proper guidance (see Hallite Bearings section) be used with this seal in heavy-duty applications. The PFR seal is available in a variety of Hallite’s high-performance Armorlene® materials to suit a wide range of demanding applications. This seal is designed to fit the ANSI B93.32-1973 and NFPA T3.19.18 housing size.
