Hallite 754 PISTON SEAL Double-Acting Polyester Face with Pre-Loaded O-Ring

The Hallite 754 double-acting piston seal is a compact, low friction seal for light to medium duty applications. The Hallite 754 is comprised of a tough, wear-resistant thermoplastic elastomer face seal which is pre-loaded by a NBR O-ring. The face material comes in a number of material options to extend operating conditions. The housing width allows a narrow width piston to be used. We recommend that an adequate bearing, such as the Hallite 506 or 87 bearing strip, is mounted on one or both sides of the seal. For further details of bearing grooves, please refer to the appropriate product data sheet.
