Hydraulics & Fluid Protection

 (60 product groups)

Hydraulic and fluid protection solutions are essential for ensuring the efficiency, safety, and longevity of systems that rely on hydraulic power or fluid transmission. These solutions prevent contamination, maintain fluid flow, and reduce wear and tear, extending the life of critical components. By minimizing breakdowns, leaks, and failures, they save costs, enhance safety, and reduce downtime. Clean, well-maintained systems also operate more efficiently, consuming less energy and meeting industry regulations while protecting the environment from leaks or spills.

Caps
Protection caps are vital for keeping dirt, debris, and moisture out of hydraulic systems, ensuring fluid cleanliness and preventing leaks during maintenance or transport. By safeguarding exposed fittings, caps reduce wear and tear, enhance system reliability, and minimize operational disruptions. These features collectively support the longevity of hydraulic components and maintain a safe and efficient work environment.

Plugs
Hydraulic protection plugs prevent contaminants from entering systems during maintenance or storage by sealing open ports and fittings. They play a critical role in maintaining leak-free operation and preserving system integrity. By protecting essential components, plugs help reduce wear, downtime, and the risk of damage, improving overall efficiency and reliability.

Hose Protection
Hose protection components, such as sleeves, wear protectors, and straps, shield hoses from abrasion, impacts, and environmental hazards, extending their service life. These components enhance safety by reducing the likelihood of leaks or bursts and ensure smooth operation. Additionally, hose straps and sleeves improve organization, keeping hoses secure and simplifying maintenance to minimize downtime.

Spiral Wrap Hose Protectors

Spiral Wrap Hose Protector, commonly known as Hose Spiral Guard or Hose Wrap, is suitable for the protection of hydraulic, pneumatic and industrial hose assemblies across a wide range of industries.

Our Hydraulic Hose Protector Spiral has excellent recovery memory to maximise the hose coverage, and this plastic spiral hose protector also has exceptional anti-crushing performance. The hose protectors maintain high abrasion resistance, which has been proven in arduous conditions. It also benefits from good resistance to UV rays. Hydraulic Spiral Wrap is suitable for wrapping single hoses or multiple hose bundles, and it comes conveniently packed in cartons for easy storage.

Our range includes Spiralguard made from High Density Polyethylene (HDPE). The Flexible HDPE has a light duty due to a thinner wall thickness when compared to the heavy duty HDPE counterpart. This flexibility allows more movability on smaller hose with better memory recovery and less pressure on radius curve of the hose.

Also available is Spiral Wrap made from Polypropylene (PP), providing maximum protection against abrasion. This PP hose wrap dramatically increases hose serviceable life, as well as reducing repair costs, downtime and improving operator safety. The light duty material compared to HDPE can be cut with scissors, and has an operating range from -40C up to 105C.
