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 manufacturer documents the following:
- EN ISO 1307:2008.
- REACH for the EPDM version (HEDUFLEX/GRECATO/EPDM).
The manufacturer states no electrical resistance for the hose, so it must not be used for combustible dust.

Help with material selection
Even though this hose is not ATEX-relevant, these two articles provide useful background on electrical resistance and industrial safety — important if you later combine the hose with electrical equipment or work in mixed environments:
Industries that use it
The hose is used in:
Agriculture and horticulture, construction, machinery, pump and compressor manufacturing and the metal industry.
Custom lengths and assemblies
The hose can be cut to length and assembled with couplings. We advise on the assembly so the hose fits your installation.
Frequently asked questions
What is the difference between the SBR and EPDM versions?
The SBR version comes from inner Ø 76 to 203 mm, −30 to +85°C and 6 bar. The EPDM version comes from inner Ø 19 to 76 mm, −40 to +125°C and 10 bar, and the manufacturer describes it as abrasion, ozone and weather resistant.
