90A Polyurethane hose is slightly stiffer than the 85A version, providing increased resistance to pressure and wear. With a Shore A hardness of 90, this hose is designed for applications requiring more strength and rigidity, such as in high-pressure air systems or heavy-duty industrial environments.
Despite its higher hardness, the hose maintains good flexibility for easy installation and movement, making it suitable for a wide range of pneumatic and fluid transfer applications.
