1 PISTON SEAL Double-Acting TECHNICAL DETAILS The Hallite PCA is a double-acting piston seal that performs well in both high- and low-pressure systems. The PCA has a square edge design on the primary sealing face paired with a square elastomer energizer. The square ring provides more stable pressure loading to the PTFE face ring, therefore it provides exceptional sealability throughout the pressure ranges. High-performance Armorlene materials, like HLX, provide outstanding wear and extrusion-resistance properties as well as large range of temperature and media compatibility. The Hallite PCA seal is well-suited for a variety of hydraulic and pneumatic reciprocating applications. The compact housing allows designers to use a narrow-width piston, but it is recommended that proper guidance be used with this seal, especially in heavy-duty applications (see Hallite Bearings section). The PCA seal is available in a variety of Hallite s high-performance Armorlene materials to suit a wide range of demanding applications.

NOTE Data given are maximum values and can apply depending on specific application. Maximum ratings of temperature, pressure, or operating speeds are dependent on fluid medium, surface, gap value, and other variables such as dynamic or static service. Maximum values are not intended for use together at the same time, e.g. max temperature and max pressure. Please contact your Hallite technical representative for application support.

4 Applications with maximum radial clearance that are using nylon, phenolic, or PTFE bearings must ensure proper clearance in accordance with the bearing recommendations to avoid metal-to-metal contact. Please refer to Hallite Type 87, Type 506, and Type 533 Specification Sheets for this information.
