TURBOCORD
TURBOCORD is a specialised sandblasting hose with extruded extreme-wear-resistant inner lining. Wear resistance is confirmed with abrasion value 60-70 mm3 per ISO 4649 - one of the industry's best ratings. 12 bar working pressure (PN) and 36 bar burst pressure (3x safety factor) make the hose suitable for high-pressure sandblasting of quartz sand, corundum and glass. Conductive inner lining (below 10⁶ ohm) + antistatic outer coating (below 10⁹ ohm) provide ATEX zone 22 suitability - a mandatory safety property in sandblasting applications where particle flow generates static electricity.

Why this hose?
The extruded NR/SBR lining is the key to TURBOCORD's industry-best-in-class wear resistance. Unlike calendered (rolled) rubber linings, extruded rubber is homogeneous throughout the cross-section without layer boundaries - meaning wear resistance is consistent from inner wall to the deepest layers. The specific NR/SBR blend is formulated to resist sharp particles at high pressure without the wall flaking or creating wear grooves.
12 bar PN / 36 bar burst is high-pressure sandblasting rating with 3x safety factor. This is above what standard industrial hoses deliver (typically 6-10 bar PN), and is specifically for high-pressure sandblasting systems where pulse hammer from particle flow can briefly exceed the nominal working pressure. The safety margin is critical in this application because wall failure under high-pressure sandblasting is potentially dangerous.
The dual conductive core + antistatic cover construction is designed for a specific problem: sandblasting generates significant static electricity from high-pressure particle flow. A conductive core discharges this charge directly to the ground connection. An antistatic cover ensures the hose's surroundings also get controlled discharge. It is a compact safety solution that eliminates the need for a separate grounding system.
Where it is used
Sandblasting workshops use the hose as standard sandblasting gun accessory. A typical installation has 5-15 m of TURBOCORD from compressed air tank to sandblasting gun. 12 bar working pressure and 36 bar burst margin ensure the hose can handle the pressure peaks that occur during pulse-active sandblasting.
Industrial facilities with ATEX zone 22 classification (glass industry, refractory, chemical powder handling) use the hose as standard powder/sand transport hose. The combined conductive-antistatic property is typically required by local risk assessments, and the hose's wear resistance allows continuous operation without frequent replacement.
Industrial cleaning and environmental services use the hose for mobile sandblasting installations. The flexible construction allows the hose to be moved between different work sites without manual disassembly, and the 40 m standard roll typically covers an entire installation length from mobile compressor to work station.
The hose is colloquially known as a sandblasting hose, slidende hose or high-pressure sand hose.

Standards and compliance
The hose is qualified per the central standards for high-pressure wear-resistant hoses with electrical properties.
- ISO 4649 (formerly DIN 53516). International standard for determination of wear resistance in rubber. The hose's 60-70 mm3 abrasion value is tested per this standard.
- ISO 8031. Determination of electrical and surface resistance in rubber hoses. The hose's core (<10⁶ Ω) and cover (<10⁹ Ω) are tested per this standard.
- EN ISO 1307:2008. European standard for rubber and thermoplastic hoses for general use.
- EN 12115. European standard for rubber and thermoplastic hoses.
- RoHS Directive (2011/65/EU). Restriction of hazardous substances.
- REACH (EC 1907/2006). Registration of chemical substances.
- ATEX 2014/34/EU. EU directive for equipment in potentially explosive atmospheres. The hose has relevant electrical properties, but explicit ATEX declaration is not in the factsheet.

Industries that use it
TURBOCORD is used where sandblasting or high-pressure abrasive transport is the core application - typically in industrial sandblasting, glass industry, refractory processing and high-pressure surface cleaning.
Industrial sandblasting is the main market. The hose leads quartz sand or corundum from compressed air systems to the sandblasting gun at 8-12 bar working pressure. Wear resistance 60-70 mm3 is industry-best-in-class - typically 2-4x better than alternative wear-resistant hoses. This means the hose can handle several thousand operating hours in sandblasting applications where a standard hose would fail after 100-300 hours.
Glass industry and refractory processing use the hose for glass, corundum and ceramic particle transport between storage and application. ATEX zone 22 suitability (conductive + antistatic) is mandatory in many glass facilities due to dust explosion risk from fine glass particles.
High-pressure cleaning industry and environmental services use the hose for abrasive injection cleaning of painted surfaces, rust removal and industrial renovation. 12 bar working pressure covers most mobile sandblasting systems, and the hose's flexibility allows it to be handled by a single operator in complex cleaning installations.
Custom lengths and assemblies
The hose can be delivered cut to desired lengths. The standard roll can be supplemented with shorter pieces or multiple rolls by arrangement.

Frequently asked questions
What is TURBOCORD particularly suitable for?
The hose is specialised for sandblasting and high-pressure transport of abrasive particles such as quartz sand, corundum and glass. The inner tube is extruded with specific formulation for extreme wear resistance (abrasion value 60-70 mm3). 12 bar working pressure and 36 bar burst pressure provide good margin for the high pressure peaks that occur in sandblasting systems.
What does abrasion 60-70 mm3 mean?
TURBOCORD's abrasion value is 60-70 mm3 per ISO 4649 - one of the best ratings in the industry. For comparison, BETONCORD/10 and SILOFLAT/DISCHARGE have 70 mm3, and standard industrial hoses 150-200 mm3. The 60 mm3 lower limit is specifically for the hardest sandblasting applications where particle erosion is a critical factor.
Why is the hose both conductive and antistatic?
The hose's inner tube is qualified as electrically conductive (below 10⁶ ohm) - providing direct discharge of static electricity from high-pressure particle flow. The outer coating is antistatic (below 10⁹ ohm) - providing moderate discharge to surroundings. Sandblasting with abrasive particles generates significant static electricity, and the ATEX zone 22 suitability is a mandatory safety property.
How many dimensions are in the range?
7 dimensions from ID 13 mm to 50 mm. These are specialised dimensions for sandblasting guns and high-pressure injector systems. All have the same pressure rating (12 bar PN, 36 bar burst) and 40 m standard roll length. Smaller dimensions (13-25 mm) are used for precision sandblasting; larger ones (32-50 mm) for high-pressure volume applications.
Which couplings are recommended?
For 12 bar sandblasting pressure, metal crimp clamps or specialised sandblasting couplings with wear-secured rings are recommended. Standard worm-drive clamps are NOT sufficient for 12 bar cyclic operation. Sandblasting guns and injector systems typically have specific coupling configurations matching the hose's ID. We typically fit couplings to the hose by arrangement.
How long does the hose last?
Wear resistance 60-70 mm3 abrasion value is industry-best-in-class for wear-resistant hoses, but sandblasting is still a very abrasive application. Service life depends on particle size, flow rate and operating frequency: 6-18 months in daily professional sandblasting, 2-3 years with occasional use. Annual visual inspection of inner wall thickness is recommended.
Which abrasive media can be transported?
The factsheet specifies quartz sand, corundum and glass as typical media - the most standard sandblasting abrasives. The NR/SBR lining is also suitable for garnet sand, steel grit and some ceramic particles. For extremely heavy-duty applications (diamond grit, sintered ceramic) we recommend specialised hoses with extra-thick walls.
Is the hose ATEX-suitable?
The hose's dual electrical qualification (conductive core + antistatic cover) makes it suitable for ATEX zone 22 (dust) installations. The factsheet does not however specify an explicit ATEX 2014/34/EU directive declaration. For formal ATEX installation we recommend cross-checking with your local risk assessment.
