Thermoplastic hoses: A robust solution for high pressure and extreme temperatures

Thermoplastic hoses are a safe and reliable choice when the demands include high pressure, extreme temperature tolerance, high abrasion resistance and low weight. At Hymatik, we supply thermoplastic hoses from Parker Hannifin – developed with a focus on safety, cleanliness and long service life in demanding environments.

What is a thermoplastic hose?

A thermoplastic hose is built up in layers of thermoplastic materials and is often fibre-reinforced. The hoses are chemically inert towards many media, do not interact with the contents and contribute to cleaner systems.

Benefits of thermoplastic hoses

Wide temperature tolerance: approx. -50 °C to +230 °C (depending on model)
High-pressure solutions: up to approx. 4000 bar (model-dependent)
Abrasion-resistant and resistant to UV, ozone and salt water
Lightweight with a compact outer diameter – ideal where space is limited
Improved internal cleanliness – reduces the build-up of contaminants and protects filters, valves and hydraulic components
Lengths up to approx. 4200 m and inner diameters right down to below 2 mm (depending on series)
Manufactured to Parker Hannifin's high technical standards

Where are thermoplastic hoses used?

Thermoplastic hoses are well suited to dynamic applications where rubber hoses typically wear out quickly:

Mobile and stationary hydraulics with repeated bending and vibration
Offshore and marine environments with UV/ozone/salt water
Industrial automation, testing and pressure testing as well as micro-hydraulics
Environments with aggressive chemicals, where chemical inertness is required

Tip: Many thermoplastic hoses are available as alternatives to traditional hydraulic standards. Always choose according to the specific specification and manufacturer data.

Guide: how to choose the right hose (STAMP)

Size: inner/outer diameter, weight and connections
Temperature: check the continuous and maximum operating temperature
Application: check the environment in the application: UV, ozone, salt water, chemicals, abrasion and impact, as well as flexibility requirements including bend radius and dynamic cycles
Media: choose the hose and inner materials according to compatibility
Pressure: match the working pressure with an appropriate safety factor

Installation and maintenance

Observe the minimum bend radius to avoid premature damage
Avoid twisting and tension during installation; use the correct hose clamps and routing
Flush and blow clean before commissioning to minimise particles
Inspection: look for wear, flattening, leaks and coupling damage
Replace according to the manufacturer's recommendations or at signs of ageing

FAQ: Quick answers

What temperatures can a thermoplastic hose withstand? As a rule, approx. -50 °C to +230 °C, depending on the model.
How high a pressure can they handle? Up to approx. 4000 bar for selected series.
Are they better than rubber hoses? In dynamic environments they often have a longer service life thanks to fibre reinforcement, low weight and high abrasion resistance.
What about chemicals? The hoses are chemically inert and resist most acids and bases. Always check compatibility with your medium.
Can they be used in small installations? Yes – with a small bend radius and low weight they are well suited where space is limited.
