Fuel Suction & Discharge Hose

Product Overview

A Fuel Suction & Discharge Hose is a specialized rubber hose designed for transferring diesel, gasoline, biofuels, and other petroleum-based products under both suction and discharge conditions. This Fuel Suction & Discharge Hose meets international standard requirements, ensuring safe and efficient fuel handling in industrial, agricultural, and marine environments. As a leading manufacturer in china, we produce this hose with a black, smooth NR/SBR tube, multi-ply high-strength synthetic fiber reinforcement with helix steel wire, and a black corrugated SBR cover. The definition of this product lies in its ability to withstand vacuum pressure while maintaining high flow rates.

The construction combines a static-dissipative tube, helix wire for kink resistance, and a durable cover. Key performance highlights include a working pressure up to 10bar (150psi) for standard duty or 20bar (300psi) for heavy-duty models, a bursting pressure of 30bar (450psi) or 60bar (900psi), and vacuum rating of 0.8bar. Core advantages are: 1) excellent flexibility for tight installations, 2) resistance to fuel-induced swelling, 3) high tensile strength from synthetic fiber and steel wire, and 4) weather-resistant cover for outdoor use. Primary applications include fuel depots, tank trucks, refueling systems, marine bunkering, and industrial transfer stations.

This hose solves critical pain points like hose collapse under suction, static electricity buildup, fuel permeation, and short service life. Our china-based factory guarantees quality with ISO certification, 100% pressure testing, and traceability. Every Fuel Suction & Discharge Hose comes with a pdf specification sheet, ensuring transparency and compliance.

Product Advantages

High Vacuum Resistance: Maintains shape under 0.8bar suction, preventing collapse and ensuring continuous fuel flow.
Fuel-Compatible Tube: NR/SBR compound resists swelling, cracking, and degradation from diesel, gasoline, and biofuels.
Reinforced Durability: Multi-ply synthetic fibers plus helix steel wire provide kink resistance and high burst strength (4:1 safety factor).
Weather-Resistant Cover: Corrugated SBR cover withstands ozone, UV, abrasion, and fuel splashes – ideal for outdoor fuel transfer.
Wide Temperature Range: Operates from -32°C to +82°C, suitable for extreme climates.
Flexible Handling: Easy to route around obstacles, reducing installation time and fitting stress.

Applicable Users: Fuel depot operators, tank truck fleets, marine fueling crews, agricultural co-ops, industrial plant maintenance teams, and construction fuel supply contractors.

Structure and Materials

Tube: Black, smooth NR (Natural Rubber) and SBR rubber compound. Resists fuel, oil, and aromatic hydrocarbons. Static-dissipative properties reduce fire risk.
Refuerzo: Multi-plies of high-strength synthetic fiber combined with helix steel wire. The helix wire prevents kinking under vacuum and provides structural integrity. This is not a Wire Braided Hose or Wire Spiral Hose for hydraulic purposes, but rather a suction/discharge specific layering.
Cover: Black, corrugated or wrapped cloth impression, SBR rubber compound. Resists abrasion, ozone, weather, and fuel spills.

Why Helix Steel Wire + Fiber Plies?

The helix steel wire acts as a rigid skeleton, preventing the hose from collapsing under vacuum pressure (0.8bar). The synthetic fiber plies carry the working pressure (10-20bar) and burst pressure (30-60bar). This combination creates a lightweight yet strong hose, different from High Pressure Hose used in hydraulics.

Fuel Compatibility

Excellent: Diesel, gasoline (short-term), kerosene, light fuel oils.
Bien: Biofuels up to B20, ethanol blends (E10-E15), mineral oils.
Not Recommended: Long-term submerged gasoline, strong acids, steam.

Hose Assembly Solutions

A hose assembly consists of the Fuel Suction & Discharge Hose plus end connections. We offer complete assemblies with crimped fittings, reusable fittings, adapters, flanges, and protective sleeves or guards. For fuel transfer, choose:

Fitting Type	Ideal para	Compatibility
Camlock couplings	Fast, frequent connections	Excellent
Flanged fittings	Permanent, high-flow lines	Excellent
Threaded (NPT/BSP)	General purpose	Good with sealant
Protective sleeves	Abrasion-prone areas	Recommended

Fuel Suction Hose vs. Hydraulic Hose

Do not confuse this rubber hose with Wire Braided Hose or Wire Spiral Hose used for hydraulics. Fuel suction hose has helix wire for vacuum resistance, while hydraulic hoses (like High Pressure Hose) have multiple steel wire braids or spirals for pressure >300bar. Using the wrong type causes collapse or burst.

International Standards Comparison

Our Fuel Suction & Discharge Hose complies with ISO 1307 and EN 1765 dimensional standards. Compared to SAE 100R4 (for suction), our helix wire pitch is tighter, offering better vacuum retention.

Solving Industry Pain Points

Hose collapse at pump inlet: Our helix steel wire maintains round shape under continuous suction.
Static electricity sparks: The tube is formulated with conductive compounds (surface resistance <10⁶ ohms).
Short life from fuel swelling: NR/SBR compound tested in diesel for 1000 hours with <15% volume increase.

Technical Standards and Certifications

Standard Compliance: ISO 1307, EN 1765, and internal factory standard (OS series).
Testing: 100% hydrostatic tested at 1.5x working pressure. Burst tests confirm 4:1 safety factor.
Certifications: ISO 9001:2015 factory certification. Available upon request: REACH, RoHS compliance statements.
Vacuum Test: Tested to 0.8bar absolute vacuum without deformation.

Installation, Operation, and Maintenance Guide

Cutting: Use a sharp hose saw. Avoid fraying reinforcement.
Fitting Installation: Use crimped fittings or banded clamps for camlocks. For reusable fittings, follow torque specs.
Bending Radius: Minimum bend radius = 10 x OD. Do not kink.
Suction Lines: Keep runs short and straight. Use protective sleeves at abrasion points.
Inspection: Before each use, check for cracks, bulges, or soft spots.
Storage: Store indoors, away from ozone (motors, transformers), between -20°C to +30°C.
