Customized Silicone Tubing for Wastewater Treatment and Water Filtration

In wastewater treatment and water filtration equipment, silicone tubing needs to provide more than flexibility. Dimensional accuracy, hardness, wall thickness, and resistance to deformation are also critical, especially when the tubing must be installed through narrow channels and bent around corners.

Recently, Zyramic, Inc., a U.S.-based manufacturer specializing in membrane modules for wastewater treatment, water reuse, MBR, UF, and MF applications, contacted us for a customized silicone tubing solution.

The Customer’s Challenge

The tubing needed to pass through a channel inside a plastic plate and make a 90-degree bend. The customer was concerned that softer silicone tubing could collapse, wrinkle, or lose its round shape at the corner, restricting the flow of air and filtered water.

Therefore, the tubing required:

1. Hardness above 60 Shore A
2. Precise dimensional tolerances
3. Sufficient wall thickness and structural support
4. Good shape retention during 90-degree bending

5. 

Customized Silicone Tubing Solution

We developed two prototype sizes for testing:

1. 7 × 11 mm
2. 4 × 6 mm

The samples were produced with controlled hardness and dimensions. During testing, both tubing sizes maintained their structural shape when bent 90 degrees inside the customer’s plastic channel, without collapsing or folding. This helped ensure smooth passage of air and filtered water.

For this application, we used a platinum curing process, which provided good structural support, dimensional stability, and transparency.

From Prototype to Mass Production

After successful testing, Zyramic placed an order for:

5,000 meters of 4 × 6 mm silicone tubing
5,000 meters of 7 × 11 mm silicone tubing

A total of 10,000 meters of customized silicone tubing was supplied.

To maintain consistent quality, we recorded the approved sample tooling, silicone material, curing temperature and time, and other key production parameters. Each production batch was also checked for hardness and dimensions.

 We had retain important information receipe and production processing data from the approved sample and production process.

Our production records include information such as:

1. Customer sample tooling
2. Raw silicone material and brand information
3. Vulcanization temperature for silicone
4. Vulcanization time 
5. Baking oven length for extrusion machine
6. Relevant extrusion process parameters
7. Addition rate of platinum curing agent .etc

During mass production, samples from each production batch are checked for key characteristics such as hardness and dimensions.

If an abnormal result is detected, the extrusion process can be adjusted and defective material can be removed. This helps maintain consistency between different production batches.

For customers purchasing thousands of meters of silicone tubing, this type of process control is particularly important because consistent tubing performance is required throughout the production run.

The tubing was supplied in 200-meter rolls, with individual labels for easier quantity checking and inventory management.

Silicone Tubing for Waste water treatment Equipment

Silicone tubing for waste water treatment equipment often needs to balance flexibility with structural strength. Customized extrusion allows manufacturers to select the appropriate hardness, dimensions, wall thickness, and curing method according to the equipment design.

Silicone Tubing for Water Filtration Modules

Silicone tubing for water filtration modules can be customized for specific installation requirements, including tight-radius bends and narrow internal channels. The Zyramic project demonstrates how prototype testing can verify tubing performance before large-scale production.

If you are looking for custom silicone tubing for wastewater treatment, water filtration, or membrane equipment, we can develop tubing according to your required dimensions, hardness, wall thickness, and application.  For silicone tubes cutting to length , you can also look for the silicone tube cutting machine ES-085 which offers precise cutting silicone tubes to length.
