Why this hose?
CARBOFLEX®/OHM/10 is the robust cousin to the standard CARBOFLEX®/U.L./OHM. The difference is primarily the pressure class: 10 bar working pressure and 30 bar burst pressure instead of 5 bar / 15 bar. It is built for processes where a pump works at markedly higher pressure, or where a broader safety margin on working pressure is preferred.
The construction has the same NBR inner tube for oil and petrol resistance, but the outer cover is SBR/EPDM (synthetic rubber) instead of CR. That gives a slightly more robust outer cover that better handles high pressure cycles, and which is ozone-resistant. The steel spiral and textile plies in the wall carry the pressure load.
Conductivity is a partial configuration: core below 10⁶ Ω (fully conductive), outer cover below 10⁹ Ω (antistatic). That is sufficient for most fuel handling processes, but not fully conductive on both sides like the U.L./OHM sister product. Choose OHM/10 when the pressure class is the driver; choose U.L./OHM when full dual-conductivity is the driver.
The cover is antistatic, not fully conductive. CARBOFLEX®/OHM/10 has a conductive core (<10⁶ Ω) but antistatic outer cover (<10⁹ Ω). If your application requires full conductivity on both sides, choose CARBOFLEX®/U.L./OHM instead.
Where it is used
CARBOFLEX®/OHM/10 is the right choice when a pump works under high load and fuel or oil must be conveyed with a large safety margin. That makes it well suited for high-pressure cleaning machines used in industrial cleaning of tanks and machinery.
In practice we see it used for tank washing of tank trucks, for pressurised fuel supply to industrial generators, and for oil filling under high pump load.
It is also used for marine hoses on vessels where pump pressure is high, and for oil recovery in waste and recycling industries at controlled high operating pressure.
The formal product name is CARBOFLEX®/OHM/10. In daily use, many simply call it "OHM/10" or "the 10-bar conductive" — the robust variant for high pump pressures.

Overpressure and underpressure values are recommended operating limits; the product can be subjected to higher loads on request. Bend radius is measured along the inside of the hose bend.
Standards and compliance
The hose is certified or documented to the following standards:

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 across industries where high pump pressure and fuel or oil handling are combined needs:
Cleaning and industrial cleaning use the hose for high-pressure cleaning machines and industrial wash systems.
Maritime and marine industries use it for bunkering and fuel supply where pump pressure is high.
Energy, environmental and waste industries use it for oil transport under high working pressure, including tank cleaning and oil recovery.
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
Why 10 bar working pressure?
10 bar is twice the standard CARBOFLEX®/U.L./OHM. The difference is built for processes where a pump works under markedly higher pressure — such as high-pressure cleaning machines, tank wash systems, and fuel distribution under pressure. The extra pressure margin also means longer service life at standard 5 bar loading.
Is the conductivity the same as U.L./OHM?
Almost. OHM/10 has a conductive core (resistance <10⁶ Ω) like U.L./OHM, but the outer cover is antistatic (<10⁹ Ω) rather than fully conductive. That is still sufficient for most ESD applications in fuel handling, but if the process requires full conductivity on both sides, choose the U.L./OHM variant.
What aromatic content does the hose tolerate?
Maximum 50 %, the same as the U.L./OHM variant. This covers standard petrol and diesel. For chemicals with higher aromatic content, a specific PTFE- or ETFE-based hose should be considered.
What temperature range does the hose tolerate?
The normal operating range is −40 °C to +90 °C, and oil temperature can be up to +100 °C. That is identical to the U.L./OHM variant — the only difference is the pressure classification.
Can the hose be supplied cut to length with couplings?
Yes. CARBOFLEX®/OHM/10 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.
