764

- The Hallite 764 double acting piston seal is a compact, low friction seal for light to medium duty applications. Advanced face geometry gives the Hallite 764 single-acting capabilities, making it an excellent choice for double-acting applications where minimal dynamic leakage is required.
- The Hallite 764 consists of a wear-resistant thermoplastic polyurethane face seal that is preloaded by an NBR O-ring. The width of the housing allows the use of a narrow piston width.
- We recommend that a suitable bearing, such as Hallite 506 or 87 bearing strip, be mounted on one or both sides of the seal. For details on bearing grooves, please refer to the appropriate product data sheet.
