Petroleum Suction Hose 400 PSI
Product Overview
The Petroleum Suction Hose 400 PSI is a high-performance rubber hose specifically engineered for the efficient suction and discharge of petroleum-based products, including diesel, gasoline, lubricants, and fuels with up to 50% aromatic content. As a critical component in fluid transfer systems, this hose meets rigorous industrial standards, ensuring safety and reliability in demanding environments. Manufactured in China under strict quality control, this rubber hose represents a dependable solution for operators seeking a durable, high-performance petroleum suction hose.
Constructed with a black, smooth NR/SBR rubber compound tube, high-strength synthetic fabric, and a steel wire helix skeleton, this high pressure hose is designed to withstand harsh conditions. Key performance highlights include a working pressure of 27.6 bar (400 PSI) , a temperature range of -32°C to +82°C, and a vacuum pressure rating of 0.8 bar. The four core advantages are: exceptional resistance to aromatic fuels, robust steel wire reinforcement for kink resistance and full suction, a weather/ozone-resistant cover for long outdoor service life, and a tight bend radius for flexible installation.
This petroleum suction hose 400 PSI is the ideal solution for tank truck loading, refueling stations, bulk fuel transfer, and industrial fluid handling. It directly solves critical pain points such as hose collapse under suction, cover cracking from ozone exposure, and premature failure from fuel swelling. Our quality commitment includes traceable production batches, pdf specification sheets, and compliance with international standard testing protocols. As a trusted manufacturer, we provide complete Service and Support to ensure your operations run smoothly.

Structure and Materials
- Tube: Black, smooth NR/SBR rubber compound. Resists swelling and degradation from petroleum products, including high-aromatic fuels.
- Reinforcement: Multiple high-strength synthetic fabric layers combined with a steel wire helix skeleton. This helix provides both pressure containment and full vacuum resistance, preventing hose collapse.
- Cover: Black, wrapped surface synthetic rubber. Formulated for weather and ozone resistance, ensuring long life in outdoor fuel transfer applications. The wrapped finish offers improved abrasion resistance compared to smooth covers.
Why Steel Wire Helix Reinforcement? Engineering Deep Dive
The petroleum suction hose 400 PSI uses a steel wire helix skeleton. Unlike a standard Wire Braided Hose or Wire Spiral Hose designed solely for pressure, the helix acts as a rigid support coil. When suction is applied, atmospheric pressure pushes inward. Without the helix, a standard rubber hose would collapse. The helix evenly distributes this radial force, maintaining a full flow area. The safety factor is designed to a minimum 4:1 burst pressure to working pressure ratio, exceeding many standard requirements. Pulse testing per EN ISO 6803 confirms the hose maintains integrity under cyclic pressure spikes common in pump start/stop scenarios.

Precise Selection Professional Guide
It’s More Than a Hose: Complete Hose Assembly Solution
A petroleum suction hose is only as reliable as its end connections. We provide complete hose assembly services using crimped fittings, reusable fittings, and adapters for various connection types. For fuel transfer, common fittings include camlock couplers, NPT threads, and flanges. Factory assembly ensures consistent crimp dimensions, eliminating leak paths. Using protective sleeves and guards over the hose assembly in high-traffic areas extends cover life.

- Routing: Avoid dragging the hose over sharp edges. Use protective sleeves or guards in abrasion-prone areas.
- Fluid Compatibility: Confirm the fuel or petroleum product is within the 50% aromatic limit. For aggressive chemicals, consult our support team.
- Storage: Store in a cool, dry place away from ozone sources (motors, transformers). Do not store coiled under tension.
- Flushing: Before switching fluid types, flush the hose to prevent contamination.
