NITROGEN/YELLOW
Highly flexible antistatic PVC hose specifically designed for transporting air, water and nitrogen gas. Used in industrial applications including petrochemical processes, where inert gas (nitrogen) is used to displace oxygen and prevent fire and oxidation risk. Two black antistatic longitudinal stripes (<10⁹ Ω) ensure static dissipation. The distinctive yellow colour marks the hose visually from other PVC hoses.

Why this hose?
NITROGEN/YELLOW is specifically designed for nitrogen and inert gas distribution in petrochemical processes. Nitrogen is used as inert gas to displace oxygen and prevent fire and oxidation reactions — particularly important at tank filling, reactors and pipeline systems where flammable media are handled.
The yellow colour is a visual safety code — easy to distinguish from other hose types at a site. Two black antistatic longitudinal stripes (<10⁹ Ω) ensure static dissipation. The hose is not formally ATEX-marked but meets the NFPA 652 thresholds for antistatic components.
Where it is used
In practice NITROGEN/YELLOW is seen in petrochemical plants, chemical reactors and inert gas distribution.
The formal product name is NITROGEN/YELLOW. In daily use: "the yellow nitrogen hose".

Help with material selection
If you are choosing a hose and are uncertain about the right resistance level or zone classification, these two articles are a good place to start:
Industries that use it
The hose is used for inert gas distribution:
Chemical, energy, construction and medical technology industries use the hose for nitrogen, air and water distribution where an antistatic wall is an advantage.
Custom lengths and assemblies
The hose can be cut to length and assembled with couplings, cuffs and threaded fittings through Particulair's custom hose assemblies.
We offer guidance on material choice, coupling system and grounding, so the hose fits correctly into the overall system. If there is any doubt about zone classification or resistance requirements, a short conversation before ordering is well worth the time.
Frequently asked questions
What is nitrogen used for in chemical industry?
Nitrogen (N₂) is an inert gas used to displace oxygen from pipeline systems, tanks and reactors. This prevents fire and oxidation risk when handling flammable or easily oxidisable media. A classic application is nitrogen purging of tank trucks before fuel loading.
Can the hose be supplied cut to length with couplings?
Yes. NITROGEN/YELLOW can be cut to length and assembled with couplings, cuffs and threaded fittings through Particulair's custom hose assemblies. We provide guidance on coupling system and sealing so the hose fits correctly into the overall installation.
How do I order the hose, and where do you deliver?
The hose is ordered through Particulair (Karlslunde, Denmark). We deliver to Denmark, the EU and selected third countries such as Norway and Switzerland. Standard dimensions can typically be delivered in 1-2 weeks; custom assemblies and larger volumes require slightly longer lead time.
What is the hose's expected service life?
Service life depends on operating conditions: loading, temperature, chemical exposure, UV and mechanical movement. In standard industrial use, expected life is 3-7 years. Aggressive conditions (high temperatures, continuous flexing, chemical vapours) reduce service life. We recommend regular visual inspection for cracks, deformation or discolouration.
How is the hose best stored before use?
Store the hose dry, at room temperature (15-25 °C) and out of direct sunlight. Avoid contact with ozone-generating equipment (welding equipment, engines). If stored on a reel, the bend must be larger than the specified minimum radius to avoid permanent deformation. Proper storage significantly extends shelf life.
What is the minimum bend radius, and what happens if I go below it?
Minimum bend radius is the smallest radius the hose can be bent to without permanent deformation or internal damage. The table above shows specific values for each dimension. Bending the hose below this limit can collapse the wall, kink the spiral or damage the inner coating. The result is reduced flow, increased pressure loss and shorter service life. Always use bend radius as a design constraint in installation.
Does the hose need to be grounded to function as an ESD component?
Yes, proper grounding is a prerequisite. The antistatic or conductive wall only dissipates static electricity if the hose is connected to ground at both ends — typically via grounded couplings on machine and tank. Without grounding, the electrical property has no practical effect and the ATEX approval is not valid in practice. We always recommend measuring loop resistance after installation.
What is the difference between an antistatic (AS) and an electrically conductive (EC) hose?
AS hoses have surface resistance between 10⁶ and 10⁹ Ω and are antistatic but not fully conductive. EC hoses have resistance below 10⁶ Ω and actively conduct static electricity to ground. For Zone 22 (dust) and Zone 1/2 (gases) AS is typically sufficient. For Zone 20 and Zone 0 — the strictest classes — EC is required. See our article "Know your ohm" for a review of the resistance classes.
