26 years of engineering hoses that survive -40°C Arctic blasts to 180°C desert heat for heavy trucks, EVs, and everything in between
EPDM vs Silicone vs Aramid – Which One’s Right For You?
EPDM Rubber
- Temp Range: -40°C to 135°C
- Burst Pressure: 300kPa
- Cost: $2-8 per meter (depending on size)
- Best For: Cars, light trucks, standard equipment
- Pro Tip: Meets SAE J20R4 standards – OEM approved!
Silicone (VMQ)
- Temp Range: -60°C to 180°C
- Burst Pressure: 400kPa
- Cost: $8-15 per meter (premium performance)
- Best For: Racing, turbocharged engines, EVs
- Pro Tip: 30% higher temp resistance than EPDM – no hardening at 180°C!
EPDM + Aramid (Kevlar)
- Temp Range: -40°C to 150°C
- Burst Pressure: 600kPa
- Cost: $10-20 per meter (industrial grade)
- Best For: Heavy trucks, excavators, mining equipment
- Pro Tip: 2x stronger than standard EPDM – handles 250kPa continuous pressure!
How We Make Your Custom Hoses (The Right Way)
- Design & DFM Validation
We optimize your design with bend radii ≥3× ID (no kinking!) and wall thickness 4-8mm based on pressure rating. Our flow simulation ensures ≤5kPa/m pressure drop at 100L/min – that’s minimal restriction!
- Material Compounding
We mix EPDM/silicone with carbon black, plasticizers, and UV inhibitors. Our EPDM compound survived 1,000 thermal cycles at -40°C to 135°C with zero cracking!
- Precision Extrusion
Straight hoses get continuous extrusion with ±0.5mm diameter tolerance. Complex shapes? Mandrel molding with ±1mm accuracy. We’ve made Y-shaped hoses with 3 bends that maintain 0.1mm wall thickness uniformity!
- Reinforcement & Vulcanization
Aramid fibers (Kevlar) embedded for strength, then vulcanized at 160°C for 10 minutes. Our 4-ply reinforcement increases burst pressure by 80% vs unreinforced hoses!
- Quality Testing (The Most Important Part!)
100% pressure testing at 150% rated pressure, plus thermal shock, ozone resistance, and fluid compatibility. Our hoses pass 100,000 pressure cycles at 120°C – that’s 500,000km equivalent!

FAQs (The Questions We Actually Get Asked)
Q: How long does it take to make 1,000 custom Y-shaped radiator hoses?
A: 5 days for material testing, 10 days for tooling (mandrels), 15 days for production – total 30 days. Need them faster? Rush options cut lead time by 30% with expedited vulcanization.
Q: How do I prevent hose collapse in vacuum applications (like turbocharger cooling)?
A: Integrate a steel wire helix (0.5mm diameter) in the reinforcement layer. We’ve tested this to 100,000+ cycles with no collapse at -50kPa vacuum.
Q: Can you color-code hoses for fleet maintenance?
A: Absolutely! We add color pigments to rubber compounds (red, blue, black, etc.) with 95% color consistency across production runs (ΔE <2). Makes identifying systems a breeze!
Q: What’s the service life of your custom radiator hoses?
A: EPDM hoses: 5-7 years/150,000km in automotive applications. Silicone hoses: 3-5 years/100,000km in high-temperature environments. Both exceed industry standards by 20-30% when maintained properly.
Q: Do you work with EV manufacturers?
A: Yes! We supply custom cooling hoses for 12 EV manufacturers worldwide. Our hoses are optimized for battery thermal management systems with 30% lower thermal resistance than standard hoses.
