Potable Water Applications

HYDROFIT™ Tubing is suitable for potable water applications with a maximum chlorine content of 4ppm (parts per million). Water heated above 70°F (20°C) and/or pressure above the rated maximum pressures will significantly reduce the service life. Avoid direct exposure to sunlight. Direct exposure to sunlight will also reduce its service life and may lead to failure. It is commonly known and good practice to inspect tubing and fittings regularly. Should there be evidence of damage, color change, cracking or hardening, fittings and tubing should be replaced immediately. All fitting and tubing should not be used near heat emitting appliances. Note: Hot and Cold water plumbing systems MUST comply with local plumbing code for pipe and fittings. Frequent visual inspections are advisable. Frequency should be predicated on the severity of the application, risk of failure or when failure could result in unacceptable downtime, damage or injury risk. Keep away from contact with ANY chemicals or aggressive liquids.

Food Quality

HYDROFIT™ Fittings and Tubing are produced with Food and Drug Administration (FDA CFR 21 177.2470 and 177.2600) approved material and can be used in food quality applications.

Side Loads

HYDROFIT™ Fittings Should not be exposed to excessive side loads. They should not be used to support brackets or other components and extreme caution should be taken during shipping and transportation to prevent undue stress and excessive side loading.

Suitability

It is the customers responsibility to gauge and ensure that HYDROFIT™ Fittings and Tubing are suitable for their specific application and variable parameters. All HYDROFIT™ Fittings and Tubing should be installed in accordance to the recommended guidelines and specifications.

Responsibility of Use

While HYDROFIT™ gives a warranty against defects in manufacture and materials, it is the responsibility of the user/installer to ensure that all fittings and tubing are suitable for their application. The installation must be carried out correctly and comply with recognized codes and national standards. All connections must be properly maintained. Please refer to Terms and Conditions.

Installation and System Testing

Fittings and tubing installations should be pressure tested and each connection inspected by pushing and pulling on the connection points prior to handing over to final user.
