Eaton Synflex Optimum thermoplastic hydraulic hoses & fittings

Empowering systems you’ve imagined— without limitations.

Eaton’s Synflex Optimum thermoplastic hydraulic hoses and fittings empower you to reimagine design. Our system engineered portfolio offers streamlined product configurations that make it easy to find the perfect combination for every application. And our commitment to innovation includes the design and technical support needed to develop more efficient, safe and productive systems.

Designed for tough jobs

Unlike traditional rubber hydraulic hoses, thermoplastic hydraulic hoses are built to withstand extreme environmental conditions and high abrasion applications. Constructed with the best properties of both nylon and polyester hoses, Eaton’s new-to-the-world hose composition elevates the standard for performance, longevity and versatility.

Hose benefits

  • Smaller OD: Synflex Optimum hoses have smaller outside diameters than rubber braided hoses with an identical internal diameter
  • UV/Ozone protection: The TPU and polyester outer cover resists ozone, ultraviolent light and aging.
  • Chemical resistance: Thermoplastic composition prevents absorption of most oils and hydraulic fluids. Multiple configurations provide chemical compatibilities not found in rubber hoses.


  • Lighter weight: 2X lighter than equivalent wire-braided rubber hoses—reducing machine weight and power requirements.
  • Higher abrasion resistance: The TPU and polyester outer cover exceeds the stringent abrasion requirements specified by today’s forklift and telehandler manufacturers.
  • Long lengths: Longer hose lengths mean less scrap and fewer coupling junctions. Hoses come in lengths of up to 500m (1,640 ft.) for the large hose size and up to 1,500 (4,921 ft.) for smaller sizes.
  • Noise reduction: Special hose reinforcement reduces machine noise.


  • Clean system: The Synflex composition does not degrade or contaminate filters and valves. Synflex hoses help maintain a cleaner system
  • Permeation resistance: Thermoplastic hoses offer better permeation resistance against gases than rubber hydraulic hoses
  • Temperature resistance: Improved hose functionality over a wide temperature range—from -54°C (00° F) up to 94°C (00° F)
  • Custom thermoforming: Eaton’s thermoforming process allows for hoses to be molded into configurations that match system design resulting in tighter routing, faster machine building and optimized performance.

System engineered to exceed expectations

Reimagine design and performance by building an engineered system that is greater than the sum of its parts. Individually, the Eaton Synflex Optimum thermoplastic hydraulic hoses and fittings offer reliable durability designed to withstand the toughest elements. But together, our assembled system enables engineers to execute safer, more effective systems.

Designed to deliver confidence

System engineered to complement Synflex Optimum thermoplastic hydraulic hoses, Eaton Synflex Optimum crimp fittings offer the same commitment to longevity and safe operation—so you can focus on creating highly-differentiated machines that drive results.

Best-in-class features come standard with Synflex Optimum crimp fittings

Single piece fitting design

Synflex Optimum fittings follow a simple one-piece design that reduces matching errors during assembly, eliminates brazing failure risks and lowers assembly time.

Captive nut

A captive nut eliminates the weak spots found in other fittings. And it evenly distributes the force applied during assembly, helping prevent cracks and leaks that halt workflows and lead to unplanned downtime.

Corrosion resistance

Dura-Kote plating comes standard in our Synflex Optimum fittings. Dura-Kote plating delivers up to 1,000 hours of corrosion resistance—giving your customers peace of mind.
