DTX Tape – Carbon Dioxide Detection Tape

This product is intended for use as a localised carbon dioxide indicator. It is not able to prevent gas leaks.

A 12-month guarantee applies once the tape is applied to joints and fittings. Extended performance may be possible, subject to environmental conditions including UV exposure and other site-specific factors.

Colour-change speed depends on: carbon dioxide concentration, flow rate, and temperature. Higher concentration and flow rate cause a faster colour-change. 

Gas concentrations below 3% will not cause a detectable colour change. 

When the tape changes from purple to yellow, and carbon dioxide flow is stopped, the colour should revert within 1 hour. 

Do not reapply the tape once removed, as foreign particles can impact adhesion and performance. 

Apply tape smoothly to avoid wrinkles that may cause irregular colour change. 

Any visible colour change should be investigated as a possible leak.

If you observe a colour change, it is recommended to confirm with a separate carbon dioxide detector. 

Use of the tape might lower or redirect leak flow; remove tape before reconfirmation.

UV rays may fade the purple colour. This tape is recommended for indoor use only.

Dust, rust, or other particles may slow the colour change.

If the tape becomes wet, it should still respond to Carbon Dioxide.

Do not apply to freshly painted pipes — may cause permanent yellowing or detection failure. 

To remove residue, clean with isopropyl alcohol.

Avoid exposure to exhaust, NOx, or SOx gases — these may cause false or permanent colour change.

Minimise overwrapping for easier identification.

Store at 10−25°C (50−77°F) and 25–50% relative humidity, out of direct sunlight
