Double Acting Piston Seal

Hallite Seals Americas introduces the newly designed 714 high-pressure compact double acting piston seal.

The redesigned sealing solution features material technology and key design enhancements to meet critical performance needs for medium to heavy duty industrial applications. It offers original equipment manufacturers (OEMS), distributors who partner with OEMs and aftermarket service providers the highest quality double acting piston seal of its type.

The redesigned Hallite 714 has a reinforced, heat stabilized, thermoplastic sealing face with a precision no gap step-cut joint, easing installation and allowing the seal to pass over ports—making it an ideal choice for double acting telescopic cylinders. It also features a rugged extrusion-resistant design that will perform in high pressure off-highway applications with considerable extrusion gap.

“The design used for the 714 seal is noteworthy because of its many benefits,” says Ryan Webster, Director Engineering for Hallite. “It employs profiled nitrile rubber energizer that responds quickly to pressure changes, providing excellent sealing characteristics under a wide range of pressure conditions. It also offers a concentrated and tangent contact patch under the sealing face for improved dynamic sealing ability. Because of this redesign and release, customers now have access to a more durable, precise double acting piston seal as well as a greatly expanded portfolio of inch sizes.”

The new Hallite 714 replaces the company’s legacy 714 series, and it is available in inch and metric ranges.
