FLEXISEAL® ROTARY SEAL
Through our distribution agreement with Parker Prädifa, we can provide their high-performance Rotary FlexiSeal® range for demanding industrial sealing applications. These rotary seals are designed for applications where shaft speeds are relatively low, typically below 1000 sfpm, while operating pressures can reach up to 10,000 psi.
The Parker Prädifa Rotary FlexiSeal® provides a reliable sealing solution for applications requiring effective sealing between a rotating shaft and stationary housing. Its design makes it particularly suitable for high-pressure, low-speed rotary applications where conventional sealing solutions may not provide the required performance.
High-Pressure Rotary Sealing
Rotary FlexiSeals are engineered for applications where both sealing reliability and resistance to high operating pressure are critical. The seal is available with either a flanged design or an O-ring on the outside diameter (OD), helping to keep the seal securely positioned in the housing while the shaft rotates.
The O-ring configuration can be supplied in different arrangements depending on the application. The O-ring may be centred along the OD or positioned within the heel of the seal, providing flexibility when selecting the appropriate rotary sealing configuration.
Rotary FlexiSeal® Design Options
A key benefit of the Rotary FlexiSeal® is the ability to configure the seal to suit specific application requirements. Custom rotary FlexiSeals can be supplied with virtually any suitable O-ring material, allowing material selection to be matched to factors such as operating conditions, temperature, fluid compatibility and pressure requirements.
Fluorocarbon (FKM) is the standard O-ring material supplied for Rotary FlexiSeal® applications, providing a versatile option for many industrial sealing environments.
Custom Rotary Seal Solutions
Every rotary sealing application has different operating requirements. Shaft diameter, rotational speed, pressure, temperature, media compatibility and housing configuration can all influence the selection of the correct seal.
Our team can help identify the appropriate Rotary FlexiSeal® configuration and material combination for your application. Custom options provide greater flexibility where standard sealing arrangements may not meet specific equipment or operating requirements.
Applications for Rotary FlexiSeals
Parker Prädifa Rotary FlexiSeals are suited to a range of industrial applications where high pressure and relatively low rotational speed are present.
They can be considered for equipment and machinery requiring dependable rotary shaft sealing, particularly where pressures can approach the upper operating range of 10,000 psi.
Typical application considerations include:
- High-pressure rotary equipment
- Low-speed rotating shafts
- Hydraulic and industrial machinery
- Rotary shaft sealing applications
- High-pressure fluid-handling equipment
- Custom engineered sealing systems
Why Choose a Rotary FlexiSeal®?
The Rotary FlexiSeal® offers several important advantages for demanding sealing applications:
- Designed for high-pressure rotary sealing
- Suitable for relatively low shaft speeds of less than 1000 sfpm
- Pressure capability of up to 10,000 psi, depending on application and design
- Available with a flanged design or OD O-ring configuration
- O-ring can be centred on the OD or positioned in the seal heel
- Custom O-ring material options available
- Fluorocarbon (FKM) supplied as the standard O-ring material
- Available as a customised sealing solution for specific applications
- Selecting the Correct Rotary Seal
Choosing the correct rotary seal requires consideration of the complete operating environment. Important factors include shaft speed, pressure, temperature, fluid or media, shaft diameter, housing dimensions and seal material.
For high-pressure, low-speed applications, the Rotary FlexiSeal® can provide a practical sealing solution where a conventional rotary seal may not be suitable. Our team can work with your application requirements to determine the most appropriate Parker Prädifa FlexiSeal® rotary seal configuration.

Frequently asked questions
1. What is a FLEXISEAL® Rotary Seal?
A FLEXISEAL® Rotary Seal is a high-performance rotary sealing solution designed for applications where a rotating shaft operates at relatively low speeds and high pressures. Through our distribution agreement with Parker Prädifa, we can supply Rotary FlexiSeal® products for demanding industrial applications.
2. What pressure can a FLEXISEAL® Rotary Seal handle?
Rotary FlexiSeals can be used in applications with pressures of up to 10,000 psi, making them suitable for demanding high-pressure rotary sealing applications. The exact suitability of a seal depends on the specific operating conditions and configuration.
3. What shaft speed is suitable for a FLEXISEAL® Rotary Seal?
FLEXISEAL® Rotary Seals are designed for applications where rotational speeds are relatively low, typically below 1000 sfpm. They are particularly suited to applications that combine low rotational speed with high operating pressure.
4. How is a Rotary FlexiSeal® secured in the housing?
The Parker Prädifa Rotary FlexiSeal® is available with either a flanged design or an O-ring on the outside diameter (OD). The O-ring helps keep the seal fixed in the bore while the shaft rotates. The O-ring can be centred along the OD or positioned in the heel of the seal.
5. Can FLEXISEAL® Rotary Seals be customised?
Yes. Custom Rotary FlexiSeal® seals can be supplied with virtually any suitable O-ring material to meet specific application requirements. Fluorocarbon (FKM) is the standard O-ring material. Contact us with your shaft size, pressure, speed and application requirements to discuss the right rotary seal solution.
