USA SEALING ZUSASES-27 Spring Energized Seal 1/2″ ID 3/4″ OD

Description

Product Overview

The USA SEALING ZUSASES-27 spring energized seal is engineered for demanding industrial environments where reliability and performance are paramount. Constructed from a black graphite filled PTFE compound, the seal offers exceptional chemical resistance, low friction, and superior wear characteristics. Its spring‑energized design ensures continuous contact with the sealing surface, compensating for thermal expansion, pressure fluctuations, and dynamic motion, thereby preventing leakage and extending service life.

Designed with a 1/2″ inner diameter and 3/4″ outer diameter, the seal fits standard rod and piston assemblies used in hydraulic and pneumatic systems. The cross‑section of 1/8″ provides a robust profile that can handle high‑speed linear motion up to 9.6 ft/s while maintaining sealing integrity. With an operating temperature range from -100 °F to 450 °F, the seal remains functional in extreme cold and heat, making it suitable for a broad spectrum of applications, from aerospace to heavy‑duty manufacturing.

Key specifications include a maximum pressure rating of 1000 psi, a maximum speed of 9.6 ft/s, and compatibility with a variety of fluids, including oils, greases, and certain aggressive chemicals. The seal’s dimensions—0.75 × 0.75 × 1 inches and a weight of 4.41 oz—allow for easy installation and handling. Manufactured by USA SEALING INC, a trusted name in sealing technology, the ZUSASES-27 model has earned a strong reputation for durability and performance in the industrial market.

Usage

This spring energized seal excels in applications that involve linear motion of rods and pistons, such as hydraulic cylinders, pneumatic actuators, and motion control systems. Its ability to maintain a tight seal under high pressure and speed makes it ideal for equipment that experiences rapid cycling, heavy loads, or variable operating conditions. Whether used in automotive manufacturing lines, aerospace testing rigs, or oilfield equipment, the ZUSASES-27 provides consistent protection against fluid leakage and contamination.

Installation is straightforward: the seal is placed into the designated groove of the rod or piston, and the built‑in spring automatically expands to fill any gaps, ensuring immediate sealing performance. The seal’s PTFE composition tolerates exposure to a wide range of fluids, including hydraulic oils, synthetic lubricants, and certain corrosive agents, reducing the need for frequent replacements. Its temperature resilience also allows it to function in environments ranging from sub‑freezing storage facilities to high‑temperature processing plants.

FAQ

What types of fluids can the ZUSASES-27 seal handle?

The seal is compatible with most hydraulic oils, synthetic lubricants, and a variety of chemicals commonly used in industrial applications. Its PTFE construction provides excellent chemical resistance, making it suitable for both standard and aggressive fluid environments.

Can this seal be used in high‑temperature applications?

Yes. The ZUSASES-27 is rated for continuous operation up to 450 °F, allowing it to perform reliably in high‑heat processes such as metal forming, extrusion, and certain aerospace testing scenarios.

How does the spring‑energized mechanism improve sealing performance?

The built‑in spring continuously pushes the PTFE sealing element against the rod or piston surface, compensating for thermal expansion, pressure spikes, and dynamic motion. This ensures a consistent seal without the need for manual adjustments, reducing wear and extending service intervals.

What maintenance is required for the seal?

Maintenance is minimal. Regular visual inspections for wear or damage, along with periodic cleaning to remove debris, are recommended. Because the seal is designed for durability, it typically outlasts standard O‑rings and requires replacement only when significant wear is observed.

Is custom sizing available?
