• Use a Hard-Wearing Barrier at Severe Contact Points
The PP profile shields hose covers from dragging, scraping and repeated rubbing against machinery.
• Reduce Snagging on Route Transitions
The curved contact surface helps the guard move past edges and adjacent components more smoothly than a sharp-profile wrap.
•Install Without Disconnecting the Hose
The spiral can be wound onto existing assemblies and around selected sections of the route.
• Extend Hose Service Life
The wear-resistant PP spiral structure reduces direct contact between hydraulic hoses and machinery components, minimizing surface wear caused by repeated friction. It helps extend hose service life and reduce maintenance needs.
1. Curved-Surface Spiral Profile
Presents a rounded external contact face for smoother movement along machine structures.
2. Polypropylene Construction
Provides a semi-rigid, wear-resistant guard for mobile and industrial hydraulic routes.
3. Spiral Wrap Coverage
Surrounds the hose while retaining flexibility between adjacent turns.
4. Retrofit Installation
Couplings permitting, without sliding a closed sleeve over the assembly.
5. Bundle Protection
Can group compatible hoses and reduce direct contact between individual hose covers.

Typical Applications
Excavators and Loaders
Protects boom, bucket and auxiliary hoses that slide against guides, frames or neighboring lines.
Mining and Quarry Machinery
Adds a replaceable outer guard where dust, vibration and rough structures accelerate hose wear.
Cranes and Material Handling Systems
Reduces scraping around masts, rollers, booms and moving lift assemblies.
Industrial Hose and Cable Bundles
Separates mixed service lines from brackets, floors and machine enclosures in exposed routes.
Measure the outside diameter of the hydraulic hose or complete hose bundle, then select the appropriate spiral guard based on the recommended bundle diameter range. Verify the guard's inner diameter, spiral pitch, bend clearance and fitting access to ensure proper installation and flexibility during operation. Consider the operating temperature, chemical exposure and outdoor conditions when confirming material suitability.
Customization Available
• Diameter and Profile - Inside diameter, outside profile, wall section and spiral pitch can be reviewed from the hose or bundle dimensions.
• Coverage and Length - Custom lengths are available to meet specific hose protection needs, covering localized wear points or entire hose sections for continuous protection.
• Color and Identification - Custom colors and identification markings are available to help distinguish different hose lines and support equipment management and maintenance.
• Packaging - Coil packaging and other agreed packaging options are available to meet customer requirements. Packaging follows the confirmed specifications, labeling and quantity requirements.
HPS-PE-SX-CS Curved-Surface PE Spiral Hose Protector complies with the applicable requirements of RoHS and REACH regulations. Material compliance is supported by relevant test reports.
Product quality is controlled through material verification, dimensional inspection, and manufacturing process monitoring to ensure consistent construction and reliable external mechanical protection.
• Material Verification - Incoming PE resin, color and required documentation are checked against the approved production specification.
• Profile Control - Spiral inside diameter, strip section, pitch and curved surface are monitored during extrusion and forming.
• Fit and Winding Check - Finished guard is wound onto the approved hose or gauge to confirm practical installation.
• Surface Inspection - Cracks, sharp edges, inconsistent profile, contamination and color variation are screened.
• Order Release - Length, size, color, labels, quantity and packaging are verified before shipment.
Frequently Asked Questions
01. What is the benefit of the curved spiral surface?
The rounded outer profile is designed to create a smoother contact face as the protected hose moves past frames or adjacent components.
02. Can the spiral guard be installed without removing hose fittings?
Yes. It is normally wound around the hose from the side, provided the route and fitting geometry allow access.
03. How should the spiral guard size be selected?
Use the measured hose or bundle OD, required clearance, bend radius and desired spiral overlap.
04. Can spiral guard protect several hoses together?
Yes, if the complete bundle diameter, relative movement and minimum bend radius are included in the selection.
Request a Sample or Quote
Send the hose or bundle outside diameter, fitting dimensions, bend radius, movement range, contact surface, required coverage length, temperature, fluid and outdoor exposure, preferred color and annual quantity. A route photo or short movement video helps MJ FLEX review the appropriate HPS-PP-SX-CS size and winding coverage.
The final quotation and sample will follow the confirmed product specification.
