About this product
ArmaFlex Class O foam pipe insulation with a 13mm wall for 6mm diameter pipework, supplied as a full 2 metre unsplit tube.
ArmaFlex Class O foam pipe insulation in this 13 x 6 x 2m size is designed for 6mm diameter pipework where a 13mm insulation wall is required.
Purpose-sized for 6mm pipework
The two numbers in the name measure different things, and mixing them up is the usual way an order goes wrong. 6mm is the pipe this tube fits. 13mm is the foam wall around it. Our guide on pipe insulation sizes works through the same point with a diagram.
Generous 13mm insulation wall
The 13mm figure refers to the thickness of the foam around the pipe, not the pipe diameter itself. This is useful to understand when comparing ArmaFlex sizes, as both the pipe diameter and insulation wall thickness form part of the product specification.
Full 2 metre unsplit tube
Each tube is a continuous 2 metres and arrives unsplit, which means it goes on over an open pipe end rather than being opened along its length and closed around the pipe. On a straight run that is an advantage, because fewer pieces means fewer joins. Where the pipe is already fixed at both ends, check the access before the tube arrives.
What does 13 x 6 x 2m mean?
The three measurements describe different parts of the product. The 13mm measurement is the insulation wall thickness, the 6mm measurement is the diameter of pipe the tube is intended to suit, and 2m is the length of the insulation tube.
This distinction is important when choosing pipe insulation because the wall thickness and the pipe size are separate measurements.
What does unsplit pipe insulation mean?
Unsplit means the tube is supplied as a complete continuous sleeve rather than having a factory-cut opening running along its length.
This format is useful where the insulation can be fitted over accessible pipework. When planning the job, check the available pipe access before installation and cut the tube to the required length as necessary.

- Small-bore pipe insulation
- Pipe installations requiring a 13mm insulation wall
- Straight pipe runs suited to an unsplit insulation tube
Benefits
- 13mm is the wall thickness, not the bore. This tube fits 6mm pipe
- Supplied unsplit, so it threads on over an open pipe end. Check the pipe is accessible before you plan around it
- One continuous 2 metre tube, so a straight run takes fewer pieces and fewer joins
- The Class O version of ArmaFlex foam pipe insulation
- Closed-cell nitrile rubber foam rather than open-cell foam, which is why it is used on chilled and refrigeration pipework as well as hot
- Closed-cell foam, so it resists water vapour through the material itself rather than relying on a separate barrier

How to use
Confirm that the pipe measures 6mm in diameter and that a 13mm insulation wall is suitable for the installation. The tube is supplied unsplit, so plan the installation around the available pipe access and cut the 2 metre tube to the required length where necessary. If the pipework is outdoors or otherwise exposed to sunlight, the insulation must be protected: Armacell requires a covering or a suitable paint, because unprotected elastomeric foam degrades under UV.
Storage
Store the tubes in a dry, clean room at normal relative humidity, around 50 to 70 per cent, and at an ambient temperature between 0°C and 35°C. Keep them protected in their packaging and away from direct sunlight until required.
Frequently asked questions
What does 13 x 6 x 2m mean?
It means the insulation has a 13mm wall thickness, is sized to suit 6mm diameter pipe and is supplied in a 2 metre tube.
What diameter pipe does this ArmaFlex insulation fit?
This size is intended to suit 6mm diameter pipework.
Is 13mm the pipe diameter?
No. The 13mm measurement is the insulation wall thickness. The pipe diameter for this tube is 6mm.
How long is each insulation tube?
Each tube is 2 metres long.
Is the ArmaFlex tube pre-split?
No. This product is supplied as an unsplit tube.
How many tubes are supplied?
This product is supplied as one 2 metre tube.
What is ArmaFlex Class O?
This listing is for the Class O version of ArmaFlex foam pipe insulation.
Can I use this tube on a different pipe diameter?
This particular size is specified for 6mm diameter pipe. For other pipe sizes, choose insulation with the corresponding pipe diameter.
What is the insulation actually made of?
Closed-cell nitrile rubber foam, black throughout. Closed-cell means the cells do not interconnect, which is why this type of insulation is used on chilled and refrigeration pipework as well as on hot services.
Can this insulation be used outdoors?
Only if it is protected. Armacell states that elastomeric foam insulation needs protection from UV radiation, using a suitable covering or paint. Left bare in sunlight it will degrade.
What temperature range is it rated for?
Armacell publishes a service temperature range of -50°C to +110°C for ArmaFlex Class O. Check the tested detail for your own installation before relying on the extremes.
