Parker 2390N Polyflex Hose: Redefining Reliability in Subsea and Onshore Hydraulic Systems

 In oil and gas operations, every component plays a role in protecting people, equipment, and the environment. Hydraulic hoses are no exception — they are the lifelines of high-pressure systems used in drilling, production, and well intervention. When the conditions are extreme, the Parker 2390N Polyflex Hose steps in as a rugged, dependable solution engineered for both subsea and topside environments.

Built for maximum durability, chemical resistance, and operational efficiency, the 2390N is designed to meet the demanding needs of offshore rigs, well service units, and onshore hydraulic systems alike.

Versatility Across the Industry

Whether you’re operating thousands of meters below the surface or at a remote onshore well site, the Parker 2390N is built for a wide range of upstream applications, including:

  • Subsea blowout preventer (BOP) control

  • Acidizing and well stimulation

  • High-pressure cementing

  • Hydraulic power transmission in drilling and production

At the heart of the hose is a thermoplastic core tube designed to resist fluid permeation and blistering — a common failure point in rubber-based hoses. This advanced construction ensures consistent performance, even in aggressive chemical environments.



Why Thermoplastic Outperforms Rubber

Rubber hoses have long been used in hydraulic systems, but under subsea pressures and with exposure to harsh fluids, they can degrade from the inside out. Microscopic fluid ingress can create blisters that rupture under rapid decompression, potentially leading to dangerous leaks.

The Parker 2390N Polyflex Hose avoids this issue entirely. Its engineered nylon tube offers excellent chemical compatibility and stability under fluctuating pressures, eliminating blistering and reducing the risk of unplanned downtime.

Engineered Strength and Protection

The 2390N is reinforced with multiple layers of high-tensile steel wire, enabling it to withstand working pressures up to [insert correct spec — typically around 5000+ psi] while maintaining a robust safety factor.

To protect against the subsea environment, the hose features a polyurethane outer jacket that resists saltwater corrosion, UV exposure, and mechanical wear. This means operators can rely on it for long-term service without worrying about jacket degradation or reinforcement corrosion.

Fewer Connections, Greater Efficiency

One major advantage of the 2390N is the ability to supply it in long, continuous lengths. In offshore systems, every connection is a potential leak point, and reducing them saves both time and risk. Continuous runs also streamline routing, reduce installation time, and improve flow efficiency across complex hydraulic layouts.

Meeting and Exceeding Industry Standards

The 2390N is manufactured to comply with API 17E and ABS requirements, ensuring it is qualified for demanding subsea duties. Whether operating in shallow waters or ultra-deep environments, this compliance confirms the hose can handle severe pressures, temperatures, and chemical exposures.

Application Highlights

  • BOP Control Systems – Reliable operation under extreme pressures to safeguard well integrity.

  • Well Stimulation & Acidizing – High chemical resistance ensures safe handling of stimulation fluids.

  • Cementing Operations – Designed for abrasive and corrosive slurries in high-pressure delivery.

Long-Term Cost Benefits

The Parker 2390N isn’t just about performance — it’s a smart investment. By reducing failures, minimizing maintenance, and extending service life, it helps operators lower total cost of ownership. Fewer replacements mean less downtime and more productive operations.

A Forward-Focused Solution

In modern oilfield operations, safety and efficiency aren’t optional — they’re essential. The Parker 2390N Polyflex Hose combines proven thermoplastic technology with heavy-duty construction to deliver a hydraulic hose capable of thriving in the world’s harshest operating environments.

If you’re seeking a hose that can handle high pressures, aggressive chemicals, and subsea extremes — while keeping your system running at peak efficiency — the Parker 2390N is a clear choice.
