• Internal diameter: 40mm (±0.5mm)
• External diameter: 52mm
• Leg length 1 (L1): 125mm
• Leg length 2 (L2): 150mm
• Bend angle: 45° (±2°)
• Wall thickness: 6mm constant
• Construction: VMQ/polyester 5-ply
• Temperature: -50°C to +180°C continuous
• Service pressure: 6 bar continuous
• Burst pressure: >18 bar

Main Applications

Engine Tuning and Automotive:

• Turbo to intercooler connections with 45° angle
• Air intake circuits post-intercooler
• Radiator coolant connections
• Turbo water and oil circuits
• Blow-off and wastegate systems

Industrial Applications:

• High-pressure pneumatic circuits
• Forced ventilation systems
• Fluid transfers under stress
• Marine applications (seawater)
• Food processing industry

5-Ply Reinforced Construction

The multi-layer structure combines premium VMQ silicone and high-tenacity polyester reinforcement. Each layer works synergistically to provide:

• Thermal resistance: maintains properties from -50°C to +180°C
• Pressure resistance: 6 bar continuous without deformation
• Burst resistance: 3× safety factor vs service pressure
• Vacuum resistance: no collapse down to -0.9 bar
• Durability: lifetime warranty, no hardening

Advantages vs Standard Hoses

✓ 5× more resistant than rubber hoses ✓ Unlimited lifespan - no cracking or hardening ✓ 6mm thickness vs 4mm standard - superior pressure resistance ✓ Chemical resistance: antifreeze, oils, fuels, compressed air ✓ Competition use: extreme vibrations, intense thermal cycles

Material Characteristics

VMQ Silicone (Polydimethylsiloxane):

• Shore A hardness: 65 ±5

FAQ - Frequently Asked Questions

Does this hose withstand high turbo pressure? Yes, the 5-ply construction with 6mm wall thickness supports up to 6 bar continuous. Ideal for engine tuning with high boost and motorsport competition.

Can the L1 or L2 lengths be cut? Yes, you can shorten the legs with a fine saw. Cut perpendicularly and deburr the edge. The 45° angle and diameter cannot be modified.

What's the difference from a 3-ply hose? The 5 plies offer double pressure resistance (6 bar vs 3 bar), better vibration resistance, and superior burst strength. Required for high-pressure applications.

Are the supplied clamps suitable? Yes, 2 stainless steel worm drive clamps are included, sized for this diameter. For critical applications, aviation T-bolt clamps available as option.

Compatible with which fluids? Water, glycol coolant, engine oils, fuels (petrol/diesel/E85), compressed air. Excellent chemical and thermal resistance.

Lifespan in intensive automotive use? Virtually unlimited. VMQ silicone doesn't harden or crack. Lifetime REDOX warranty against material defects. Only external mechanical damage could harm it.
