ustom Diameter TPU Covered PTFE Braided Hose for Food, Pharmaceutical and Chemical Transfer

When a fluid transfer system requires chemical resistance, clean handling, wear protection and high temperature performance, an exposed stainless steel braided hose may not always be the most suitable option. In food, pharmaceutical, cosmetics, beverage, paint, adhesive and chemical transfer applications, the hose often needs a smooth outer surface to protect the reinforcement layer from wear, contamination and external damage.

Our custom diameter TPU covered PTFE braided hose is designed for demanding industrial and hygienic transfer systems. It uses a smooth PTFE inner tube as the fluid contact layer, a high-strength 304 stainless steel braided wire layer as the reinforcement structure, and a smooth TPU/PU outer cover for additional protection.

This structure provides a strong balance of chemical resistance, pressure support, cleanliness, wear resistance and flexible installation, making it suitable for clean production lines, corrosive chemical transfer, viscous media transfer and high-temperature hydraulic or pneumatic applications.

What Is a TPU Covered PTFE Braided Hose?

A TPU covered PTFE braided hose is a reinforced hose made with a PTFE inner tube, stainless steel braided reinforcement and a smooth TPU/PU protective outer layer. The PTFE inner tube provides chemical resistance and temperature stability, while the 304 stainless steel braid improves pressure resistance and mechanical strength.

The outer TPU/PU cover helps protect the stainless steel braid from abrasion, contamination and external contact. It also provides a smoother and cleaner surface compared with exposed stainless steel braid, making the hose more suitable for applications where cleanliness, handling safety and appearance are important.

Compared with standard stainless steel braided PTFE hose, this covered hose is better suited for production environments where the hose may contact equipment surfaces, floors, operators or clean processing areas.

Key Features of the TPU Covered PTFE Braided Hose

1. Smooth PTFE Inner Tube for Chemical Resistance

The inner tube is made of PTFE, which provides excellent resistance to many chemicals, solvents and industrial fluids. It is suitable for applications involving corrosive chemical fluids, fuel, gas, strong acids, strong alkalis and organic solvents.

The smooth PTFE inner surface helps support stable fluid transfer and reduces material buildup inside the hose, making it useful for clean transfer and viscous media applications.

2. 304 Stainless Steel Braided Reinforcement

The hose is reinforced with high-strength 304 stainless steel braided wire. This reinforcement improves pressure resistance and helps protect the PTFE inner tube from expansion, deformation and mechanical stress during operation.

The stainless steel braid gives the hose strength while still allowing practical flexibility for equipment connection and installation.

3. Smooth TPU/PU Outer Cover for Protection

The smooth TPU/PU outer layer protects the stainless steel braid from wear, contamination and external damage. It also creates a cleaner surface that is easier to handle and better suited for clean production environments.

The outer cover can also help reduce direct contact between the stainless steel braid and surrounding equipment, floors or operators.

4. Better Cleanliness and Wear Resistance

The covered structure provides better cleanliness and wear resistance than exposed braided hose. This is important for food, pharmaceutical, cosmetics and beverage production lines where the hose surface may need to remain cleaner during use.

The smooth outer cover also helps prevent dirt, dust or product residue from being trapped inside the stainless steel braid.

5. Low Permeability and Strong Chemical Stability

PTFE has low permeability and is inert to most chemicals and solvents. This makes the hose suitable for demanding transfer systems where material compatibility and long-term stability are important.

It is especially useful for corrosive fluids, solvents, paints, adhesives and other media that require reliable hose material performance.

6. Wide Temperature Resistance

The hose is designed for a temperature range from -70°C to +260°C, making it suitable for both low-temperature and high-temperature working environments.

It can be used in chemical transfer, high-temperature hydraulic systems, pneumatic systems and process fluid applications where temperature stability is required.

7. Custom Outer Cover Colors

The smooth outer cover can be customized in colors such as black, red and blue according to application, identification or branding requirements.

Color customization can help users distinguish different transfer lines, media types or production areas more easily.

Typical Applications

The custom TPU covered PTFE braided hose is suitable for a wide range of clean and demanding fluid transfer systems, including:

Pharmaceutical fluid transfer
Food-grade fluid transfer
Cosmetics production lines
Beverage processing systems
Paint transfer
Adhesive transfer
Viscous media conveying
Corrosive chemical fluid transfer
Fuel and gas transfer
Strong acid and strong alkali transfer
Organic solvent transfer
High-temperature hydraulic applications
Pneumatic transfer systems
Pump and tank connections
Clean equipment connections
Industrial production line piping

Its combination of PTFE chemical resistance, stainless steel braided reinforcement and smooth TPU/PU outer cover makes it suitable for applications where ordinary exposed braided hoses may not provide enough cleanliness or external protection.

Why Choose a TPU Covered PTFE Braided Hose Instead of an Exposed Braided Hose?

A standard stainless steel braided PTFE hose provides strong pressure resistance and chemical compatibility, but the exposed braid may collect dust, trap residue or scratch nearby equipment surfaces. In clean production environments, exposed braid may not be the best choice.

A TPU covered PTFE braided hose provides the same core advantages of PTFE and stainless steel reinforcement while adding a smooth protective outer layer. The cover helps improve cleanliness, wear resistance and handling convenience.

For customers who need a food grade PTFE hose, pharmaceutical PTFE hose, chemical resistant PTFE hose, paint transfer hose or adhesive transfer hose, this product provides a practical solution for clean, flexible and durable fluid transfer.Custom TPU covered PTFE braided hose with smooth PTFE inner tube, 304 stainless steel braided reinforcement and smooth TPU/PU outer cover. Available in 5/32", 1/4", 5/16", 3/8", 1/2", 5/8", 3/4" and 1" sizes for food, pharmaceutical, cosmetics, beverage, adhesive, paint and chemical transfer applications.
