LLDPE Chemical Dosing Tubing
Flexible, Reliable and Suitable for Most Water Treatment Applications
LLDPE (Linear Low-Density Polyethylene) tubing is widely used in chemical dosing systems due to its excellent flexibility, durability, and compatibility with a broad range of water treatment chemicals.
Manufactured from non-contaminating material, LLDPE tubing provides a reliable solution for chemical injection systems, including peristaltic and diaphragm dosing pumps.
Key Benefits:
- Excellent chemical compatibility
- Flexible and easy to install
- Durable construction for long service life
- Available in metric and imperial sizes
- Black tubing option available with UV stabilisation
- Suitable for indoor and general water treatment applications
- UV-stabilised black tubing for outdoor installations
Common Applications:
- Swimming pools and aquatic facilities
- Chlorine dosing systems
- Acid and pH correction systems
- Cooling towers
- Water treatment plants
- Industrial dosing applications
PTFE Chemical Dosing Tubing
Premium Chemical Resistance for Demanding Applications
PTFE (Polytetrafluoroethylene) tubing provides superior chemical resistance and is recommended for applications involving aggressive chemicals, higher temperatures, or where maximum compatibility is required.
PTFE tubing offers excellent resistance to acids, solvents, oxidisers, and other challenging chemicals, making it ideal for demanding chemical dosing environments.
Key Benefits:
- Outstanding chemical resistance
- Suitable for aggressive chemicals
- Excellent temperature resistance
- Long service life in demanding applications
- Low friction internal surface
Common Applications:
- Industrial chemical dosing
- High-purity applications
- Aggressive chemical injection
- Specialised water treatment systems
