METAL HOSE PUR 105 AD
Very robust metal protection conduit with PU coating — combination of metal stability and polyurethane protection. Highly flexible and liquid-tight (IP 68 per EN/IEC 60529), ideal for cable protection in electrical installations, switch cabinets and switchgear where IP 40 (uncoated) is insufficient. The metallic blue PU coating provides visual differentiation and UV protection.

Why this hose?
METAL HOSE PUR 105 AD is a combined construction: metal conduit flexibility with PU coating that makes the hose liquid-tight. Where METAL HOSE 101 AD is IP 40 (dust-only protection), 105 AD is IP 68 — fully liquid-tight under specific pressure conditions.
The practical use: cable protection in humid industrial installations, marine environments and outdoor electrical plants. The blue PU coating also protects against UV and provides visual differentiation.
Where it is used
In practice METAL HOSE PUR 105 AD is seen as cable protection conduit in humid or outdoor installations.
The formal product name is METAL HOSE PUR 105 AD. In daily use: "the blue metal conduit".

Dimensions and ordering
The table shows 6 standard dimensions. Bending radius is measured along the hose's centre axis. The nominal connection size is the outer dimension that determines the coupling type, while inner diameter is the effective flow opening.

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:
- IP 68 per EN/IEC 60529. Highest international protection class against liquids (continuous immersion under specific pressure conditions).
- REACH (EC 1907/2006) and RoHS 2011/65/EU. The manufacturer holds declarations of compliance.

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 cable protection in humid or outdoor environments:
Mechanical, ship and energy industries use the hose for cable protection in environments where liquid-tightness (IP 68) is a formal requirement.
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 the difference between 105 AD (PU) and 101 AD (without PU)?
The PU coating makes 105 AD liquid-tight (IP 68) and provides UV protection. 101 AD is IP 40 — dust protection only. Choose the PU variant in humid or outdoor environments; choose standard 101 AD for indoor hot installations.
How hot can the hose get?
Normal operating range is −40 °C to +90 °C, and short-term peaks up to +125 °C are permitted. The PU coating limits it to lower temperatures than the uncoated 101 AD version.
Can the hose be supplied cut to length with couplings?
Yes. METAL HOSE PUR 105 AD 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.
