Characteristics and performance

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 recommends proper guidance (see Hallite Bearings section) be used with this seal in heavy-duty applications.

Product details

This seal is designed to fit the ANSI B93.32-1973 and NFPA T3.19.18 housing size.

The part numbers listed below only show standard material options for both the face seal and energizer, where applicable. For a complete list of the material and energizer options along with part numbering structure, please see the complete PDF datasheet or click PFR Data Tables.
