Crimping an Adapter onto Your Flexible Shaft with a Hydraulic Press

In the world of flex shaft plumbing, crimping an adapter onto a flexible shaft can be a crucial step in the assembly process of your shaft with the sewer cleaning machines that do not use set screws to hold the flex shaft in place at the power source. This method ensures a secure and reliable connection, enabling efficient operation and optimal performance of a flex shaft sewer machine. In this post, we will provide a step-by-step guide on how to crimp an adapter onto your flexible shaft using a hydraulic press. We will also emphasize the importance of the hydraulic press in achieving a successful crimping process.

Understanding the Importance of Crimping

Crimping can play a vital role in the construction and maintenance of flex shaft sewer machines. By crimping an adapter onto a flexible shaft, a strong and durable connection is established. This connection ensures that the flex shaft remains securely attached to the adapter during operation, preventing any potential detachment or loss of performance. The hydraulic press is an indispensable tool in this process, providing the necessary force and precision to achieve a reliable and long-lasting crimp.

Gather the Necessary Tools and Equipment

Before embarking on the crimping process, it is essential to gather all the required tools and equipment. This includes a hydraulic press, a crimping die set specifically designed for your adapter, a flexible shaft, the adapter itself, and any necessary safety gear such as gloves and eye protection. Having everything at hand ensures a smooth crimping process.

Step-by-Step Guide to Crimping an Adapter onto Your Flexible Shaft

1. Prepare the Hydraulic Press

Position the hydraulic press on a stable surface, ensuring it is securely anchored to prevent any movement during the crimping process. Adjust the press to the appropriate pressure setting as recommended by the manufacturer for the specific adapter and flexible shaft being used. This ensures the correct amount of force is applied during the crimping operation.

2. Inspect and Prepare the Flexible Shaft and Adapter

Thoroughly inspect the flexible shaft for any signs of damage or wear. Clean it meticulously, removing any debris or dirt that may hinder the crimping process. Similarly, examine the adapter for any defects or imperfections that may affect the crimping outcome. Ensure that the adapter is compatible with the flexible shaft and fits securely.

3. Position the Assembly in the Hydraulic Press

Carefully position the prepared flexible shaft and adapter assembly in the crimping die set. Proper alignment is critical, as any misalignment can result in an imperfect crimp. Ensure that all components are positioned correctly within the die set and double-check that the assembly is secure.

4. Apply Pressure with the Hydraulic Press

Activate the hydraulic press, allowing it to exert the necessary pressure to create the crimped connection. Follow the manufacturer’s guidelines for the recommended pressure and duration of the crimping process. The hydraulic press will provide the precise and controlled force required to achieve a secure and uniform crimp.

The difference between our flexible shafts and Ridgid Flexshafts

Many of our customers assume we provide replacement shafts for their Ridgid Flexshaft. But that is not the case. We do not claim that we have a replacement shaft for a Ridgid Flexshaft and we do not provide replacement cables for Ridgid K102 or Ridgid K204 sewer cleaning machines. We manufacture our own brand of shafts, and by chance our clients started adapting them to their Ridgid K102 and Ridgid K204 sewer cleaning machines.

They also informed us that our flexible shafts are a bit more rigid than the Ridgid Flexshafts. The advantage of having a more rigid flexible shaft is that when more torque is needed then a more rigid shaft is less likely to coil on the inner diameter of the pipe (which makes it difficult to navigate forward), plus the shaft also lasts longer.

In contrast to Ridgid K102 and Ridgid K204 sleeves our sleeves are slightly different. Our protective sleeve is designed to support a more rigid flex shaft and has friction rings at the ends of it.

Flexible shafts with the 102/204 adapters already crimped on them

On our online store you can find a complete set which includes a flexible shaft, protective sleeve and a 102/204 adapter to use with your 102/204 sewer cleaning machine. For your convenience, the 102/204 adapter is already crimped onto the flexible shaft for you so you don’t need to hassle with getting a crimping tool.

This is not an original Ridgid flexible shaft, we do not provide replacement cables for the Ridgid K102 or Ridgid K204 sewer cleaning machines.


Crimping an adapter onto a flexible shaft is a fundamental process in flex shaft plumbing. With the assistance of a hydraulic press, you can ensure a strong and reliable connection, vital for the proper functioning of a flex shaft sewer machine. By following the step-by-step guide outlined in this article, you can confidently achieve a successful crimping process and enhance the performance of your flex shaft plumbing equipment. Remember to always prioritize safety and refer to the manufacturer’s instructions for specific guidelines and recommendations.
