If you move fuel for a living—on a dock, across a yard, or between tanks—you already know the hose is the least glamorous and most critical link in the chain. I’ve handled enough rigs to say this plainly: a good Rubber Oil Hose prevents tiny leaks from becoming big cleanups. And—surprisingly often—keeps your pump from working twice as hard.
Fuel blends are getting trickier—bio-diesel mixes, higher aromatics in some regions, tighter emissions rules in ports. The quiet shift I’m seeing: buyers insist on hoses verified for conductivity, vacuum stability, and compatibility with blends (B20, E10). Downtime penalties are brutal, so 150 PSI softwall hoses with steel helix are the default for suction and discharge on fixed and mobile systems.
Origin: CHANGAN DISTRICT, SHIJIAZHUANG, HEBEI, CHINA. Application: softwall hose designed for suction and delivery of petroleum products (aromatic content typically up to 50%—real-world use may vary). To be honest, many customers say it’s the “put it on and forget it” type when installed with proper bends and supports.
| Item | Spec (≈ indicates typical) |
|---|---|
| Working Pressure | 150 PSI (≈10 bar) |
| Safety Factor | ≥ 3:1 (burst ≈ 450 PSI) |
| Temperature Range | -20°C to +82°C (intermittent peaks may vary) |
| Tube | NBR, black, smooth, fuel/oil resistant |
| Reinforcement | High tensile textile plies + embedded steel wire helix |
| Cover | NR/SBR blend, wrapped finish, abrasion & ozone resistant |
| ID Range | 19–200 mm (3/4"–8") |
| Vacuum Rating | up to 0.9 bar (≈90%) |
| Aromatics | up to ≈50% volume |
| Lengths | 10–60 m (custom on request) |
| Ends | Flange, Camlock, NPT—assembled or loose |
| Electrical | Conductive 6 Ω/m (ISO 8031) |
Materials: NBR tube for fuel resistance; NR/SBR cover for toughness; textile cords for flexibility; steel helix for vacuum integrity. Methods: mandrel-built, wrapped cover cure, vulcanized. Tests (type & routine): hydrostatic (ISO 1402), dimensional (ISO 4671), vacuum stability, adhesion (EN 1765 guidance), electrical continuity (ISO 8031). Proof test often 1.5× WP; burst typically ≥3× WP. Service life? Around 3–5 years in fair conditions—bends, UV, and fuel type change the story.
Marine bunkering lines, terminal fuel transfer, construction site bowsers, refinery loading bays, mining diesel distribution, and backup generator farms. I guess the rule is simple: if it sucks and pushes petroleum, a Rubber Oil Hose with a helix is the safe bet.
| Vendor | WP | Standards/Tests | Lead Time | Customization | Notes |
|---|---|---|---|---|---|
| ZSMARTFLEX (this model) | 150 PSI | ISO 1402 / ISO 8031; EN 1765 guidance | ≈10–20 days | ID/OD, branding, ends | Solid value, consistent QC |
| Vendor A | 130 PSI | Basic factory test | ≈25–35 days | Limited | Budget option |
| Vendor B | 150 PSI | API 1529, extra certs | ≈30–45 days | Yes | Premium price |
Options: size 3/4"–8", branding, color line, antistatic wire, flange drilling (ANSI/DIN), cut lengths. QC flow: compound check → cord/helix alignment → mandrel build → vulcanization → proof test → continuity test → dimensional audit → packing. Certifications often include ISO 9001; REACH/RoHS conformity statements are available on request.
“Doesn’t flatten under hard suction,” one terminal supervisor told me. Another mentioned the cover “shrugs off” daily dragging—within reason, of course. Little things, big difference.
Built and tested against ISO 1402 (hydrostatic) and ISO 8031 (electrical). Dimensional checks per ISO 4671; design aligns with EN 1765 requirements for oil suction/discharge hoses. For aviation applications, defer to API 1529 specifics. Always verify your blend compatibility.
