Hose Types and Uses
- Fuel Line Hose (SAE J30): NBR‑based liners for gasoline, diesel, and blends. Low‑pressure carbureted options for easy routing; EFI variants with higher working/burst pressure and low permeation; anti‑static constructions to dissipate charge.
- Coolant/Radiator Hose (SAE J20 EPDM): EPDM inner/cover for hot coolant and ozone resistance. Dual fiber or fiber + steel wire reinforcement for collapse resistance; smooth or corrugated profiles for movement.
- Turbo Oil and High‑Temperature Lines: FKM liners with aramid/fiber reinforcement, or PTFE‑lined assemblies for oil mist and peak temperatures up to ~200°C.
- PCV/EVAP and Air Intake: Oil‑mist resistant tubes with stable vacuum performance; optional corrugations for flexibility without collapse.
- Brake Booster Vacuum: Non‑collapse walls maintain consistent brake assist; covers resist heat and abrasion.
- Power Steering/Hydraulic: Braided 1SN/2SN and jack‑grade options handle pulsation, heat, and abrasion, with selected models exceeding 3000+ psi.
- Heater and HVAC: Flexible EPDM heater hose for reliable cabin comfort systems.
Materials and Construction
- Elastomers: EPDM for hot coolant; NBR for fuel/oil; FKM for high‑temperature oil service.
- Reinforcement: Dual fiber braids for flexibility; steel wire braid for pressure; spiral reinforcement for pulsation control and kink resistance.
- Covers: Smooth or corrugated with abrasion and ozone protection; flame‑retardant options where applicable.

Performance and Standards
- Temperature: Standard ‑40°C to 120°C; high‑temp variants up to ~200°C near turbo/exhaust routes.
- Pressure/Vacuum: From vapor lines to EFI and hydraulic steering; designed for required working and burst ratings with vacuum stability where needed.
- Permeation/Electrical: Low‑permeation liners for emissions control; anti‑static and non‑conductive options for system safety.
- Flexibility: Optimized bend radius; corrugations available to absorb movement.
- Standards: Fuel hose to SAE J30; coolant/radiator to SAE J20; materials aligned with ASTM D2000.
Customization, Assemblies, and Quality
Specify liners, reinforcement, covers, IDs/ODs, and formed shapes from drawings or samples. Assemblies can include barbed, crimped, or quick‑connect fittings, clamps, and protective sleeves.
Each assembly is validated with pressure, leak, and dimensional tests. Full‑process inspection and batch traceability support consistent quality.
Installation and Care
Route away from heat sources, maintain recommended bend radii, and secure with suitable clamps. Inspect for hardening, cracking, swelling, or chafing. Replace proactively to avoid downtime.
FAQs
How do I choose the right size and construction?
Confirm medium, temperature, pressure/vacuum, and routing limits. Match EPDM/NBR/FKM liners, reinforcement level, and cover properties. Provide drawings or samples for exact fit.
Can you supply test reports and certificates?
Yes. Spec sheets, third‑party test reports, and certificates can be provided with samples or orders.
What’s the difference between EPDM and NBR?
EPDM performs well in hot coolant and ozone exposure. NBR is suited for fuel and oil. Choose FKM or PTFE‑lined designs for high‑temperature oil service.
When should anti‑static or non‑conductive designs be used?
Use anti‑static liners in fuel systems to dissipate charge. Select non‑conductive variants where electrical isolation is required.
