ATEX Hoses – Explosion-Protection Compressed Air Hoses in Polyamide (PA12)
For compressed air supply in hazardous areas, you need hoses with proven suitability – not just claimed. The STASTO ATEX hose series PA-AYA in polyamide is designed for exactly that: depending on the variant, the hoses cover a wide range of dimensions and are available as cut-to-length, on a reel, or on a drum. We provide the ATEX documentation for each series.

Why STASTO
ATEX-rated tubing with certification, not just claims
Procurement for regulated Ex zones requires both: the right product and reliable documentation. The PA-AYA series delivers both from a single source.
Certified Ex-rated
The PA-AYA series is designed for use in potentially explosive atmospheres. The corresponding ATEX documentation is available on request, matched to the selected variant.
Polyamide as a proven tubing material
Durable, age-resistant polyamide in black — a material well established in STASTO's pneumatics range.
One size range, many applications
From small control lines to larger supply cross-sections: multiple OD/ID sizes within one series, depending on variant.
By the metre, reel or drum
Delivery format as needed: by the metre or pre-configured on a reel or drum – depending on item and variant.
Guide
What makes a hose ATEX-compliant
ATEX Directive 2014/34/EU, zone classification and material selection: the key fundamentals for choosing an ATEX-rated compressed air hose. For the zone classification of your plant, please consult a qualified planner or your explosion protection officer.
Regulatory framework and zones
- ATEX 2014/34/EU
- Equipment for use in potentially explosive atmospheres is subject to the ATEX product directive. Suitability must be demonstrated through appropriate design and documentation.
- Zone 1 (gases/vapours)
- Area where an explosive atmosphere of gases or vapours may occasionally occur. The PA-AYA series covers Zone 1 depending on the variant.
- Zone 21 (dusts)
- Dust-laden areas where an explosive atmosphere may occasionally occur – for example in mills or bulk solids handling.
- Other zones
- Whether a variant is suitable beyond Zone 1 and 21 is verified on request based on the documentation for the specific part number.
Material and technical data
- Polyamide (PA)
- Well-established hose material in pneumatics: mechanically robust and resistant to ageing, black finish.
- Ex Rating vs. Material
- What matters is the certified design of the PA-AYA series — not the material alone. A visually similar standard PA tubing does not carry this certification.
- Operating Pressure
- The permissible operating pressure depends on size and temperature. The specifications in the datasheet of the selected part number are binding.
- Temperature Range
- The operating temperature range varies by variant. Please refer to the datasheet of the specific part number.

Applications
Where PA-AYA Series ATEX Hoses Are Used
Wherever compressed air is routed into an area with a potentially explosive atmosphere and explosion protection must be ensured using suitable equipment. The specific approved zones depend on the variant.
Chemical Industry
Compressed air and control lines in plant sections with zone classification, where solvent- or gas-containing atmospheres may occur.
Process Engineering & Process Plants
Supply of pneumatic actuators and controls in classified process areas – check suitability per variant using the datasheet.
Mills, Bulk Materials & Food Processing
Dust-laden areas of Zone 21, where the PA-AYA series is suitable depending on variant.
Compressed Air Supply in Hazardous Areas
Supply and control lines from distribution to point of use – supplied by the meter, on a reel, or on a drum.
Machine & Plant Engineering
Series-built machines and special-purpose systems installed in classified operating areas that require documented ATEX compliance.
Paint & Coating Systems
Supply lines in areas with solvent-laden atmospheres, such as paint booths and coating lines.
Delivery & Certificates
Delivery Formats, Availability and ATEX Documentation
Operating pressure, temperature range and approved Ex zones vary by version. Please refer to the datasheet of the specific part number for the applicable values.
Availability per Variant
Availability varies depending on size and configuration – please check or inquire per variant.
Delivery Format
Depending on the item, supplied as cut length, on a coil (e.g. 50 m) or on a drum.
Lead Time on Request
We will confirm the binding lead time for the specific variant upon request.
ATEX Documentation
Documentation is provided for the respective series or variant – please request it together with your inquiry.
Our approach
Three steps to the right ATEX hose variant
Tell us the parameters – we'll coordinate dimensions, packaging and certification with you.
Describe your requirement
Zone classification, required bore, length and operating conditions – the more precise the details, the more accurate the recommendation.
Coordinate the variant
We propose the suitable dimension from the PA-AYA series and clarify operating pressure and temperature range based on the datasheet.
Certification and delivery
You receive the ATEX documentation for the selected variant, plus delivery by the metre, reel or drum.
Frequently Asked Questions
ATEX hose: frequently asked questions
Answers on suitability, dimensions, certifications, and technical specifications of the PA-AYA series.
Is the PA-AYA series suitable for hazardous areas?
Yes, the ATEX hose series PA-AYA is designed for use in hazardous areas. Which zones – including Zone 1 and 21 – a specific variant covers is specified in the respective datasheet.
What's the difference between an ATEX hose and a standard PA hose?
The key factor is the proven suitability for use in hazardous areas, together with the corresponding ATEX documentation. A visually similar standard polyamide hose does not have this certification and must not be used in classified areas.
Which dimensions are available in the PA-AYA series?
The series includes several outer/inner diameters, for example Ø 6/4, Ø 10/8, Ø 12/10, and Ø 16/12. Depending on the variant, we supply it as cut-to-length, on a roll, or on a reel – please inquire about the specific variant.
How do I get the ATEX certification for the hose?
We provide the ATEX documentation matching your selected series or variant. Simply request it together with your inquiry.
What operating pressure and temperature can the hose withstand?
Both aspects are variant-dependent and must also be assessed based on temperature. You'll find the relevant values in the datasheet for the respective part number; we'll send it to you upon request.
What does the ATEX Directive 2014/34/EU regulate?
The ATEX Directive 2014/34/EU sets out the requirements for equipment and protective systems intended for use in potentially explosive atmospheres. For compressed air hoses, this means suitability for the relevant zone must be proven through appropriate design and documentation.
Who determines the Ex zone in my facility?
Zone classification is the operator's responsibility, typically supported by an approved specialist planner. Consult your Ex-protection officers for classification and approval – we're happy to recommend the suitable hose variant afterwards.
Does STASTO help with variant selection?
Yes. Just tell us your zone classification, required bore size, and length – we'll help you select the right PA-AYA variant and provide the corresponding documentation.
