Protect Hydraulic Hoses From Abrasion & Contact Wear
A hydraulic hose can be perfectly specified internally yet still suffer because of what keeps rubbing against it externally. Hardie Hose PSG Spiral Guards add a protective outer layer around compatible hose assemblies exposed to abrasion, hose-to-hose contact, machinery movement & demanding working environments.
With 11 sizes currently available from 12mm through to 110mm, the range covers everything from smaller hose assemblies to substantially larger protected runs. Most sizes are supplied in 20 metre boxes, while the larger 90mm & 110mm options are supplied in 10 metre boxes, giving maintenance teams a clear starting point when matching protection to the hose outside diameter & required coverage.

What Are Hardie Hose Spiral Guards?
Picture the areas on a machine where a hose passes a bracket, crosses another line or moves every time an attachment cycles. Spiral guard wraps around the exterior of a compatible hose to place an additional barrier between that hose & potential sources of external wear.
Rather than changing the hose's core function, the guard helps protect its outer surface where contact can occur.
That makes spiral guarding relevant where hoses encounter:
► Abrasive surfaces
► Hose-to-hose rubbing
► Machinery frames
► Repeated movement
► Workshop floors
► Rough ground
► External mechanical contact
Guarding should complement a correctly selected & routed hose assembly rather than compensate for an unsuitable one. Hose specification, fittings, routing, bend requirements & equipment compatibility remain fundamental.
Why Choose Hardie Hose Spiral Guards?
Replacing guarding is a very different maintenance proposition from discovering that the hose underneath has been taking repeated external punishment. Where a compatible assembly is exposed to abrasion, spiral guarding provides a sacrificial layer between the hose exterior & surrounding environment.
Help Shield High-Contact Areas
A hose passing near steelwork or another line may repeatedly contact the same area as equipment operates. Suitable spiral guard places protection around the hose at these exposed points.
Protect Moving Hydraulic Lines
Mobile plant changes geometry constantly. Boom movement, steering, cylinders, linkages & attachments can all alter the position of a hose during operation.
Separate Adjacent Hose Runs
Multiple hydraulic or pneumatic lines routed through the same area can contact one another as machinery vibrates or articulates. Appropriate guarding can provide another protective layer around compatible assemblies.
Make Wear Patterns Easier To Spot
A scuffed guard can tell a useful maintenance story. Concentrated wear in one location may point technicians towards a bracket, neighbouring hose or changing clearance that deserves closer inspection.
For related hose-management equipment, Air Hoses & Reels provides options for workshop & compressed-air applications.
Common Applications
Earthmoving & Excavation Equipment
Watch an excavator boom through a complete operating cycle & hose movement becomes obvious. Hydraulic lines can change position significantly as cylinders extend, attachments move & the boom articulates.
Spiral guarding can provide additional external protection for compatible hose assemblies exposed to recurring contact.
Agricultural Machinery
Farm equipment combines dust, vibration, movement & long operating periods. Tractors, implements & other hydraulic machinery can contain exposed hose runs where abrasion protection deserves attention.
For water-moving applications elsewhere around the property, Irrigation Systems & Pumps covers related pumping equipment.
Workshop Pneumatic Systems
Air lines dragged around work areas can encounter concrete, frames & equipment edges throughout the day. Appropriate spiral protection can help shield compatible hose exteriors in high-contact areas.
Mobile Plant
A hose that clears everything while parked may behave very differently once the machine starts working. Turning, lifting, tilting & articulation can all change clearance.
Washdown Equipment
Dragging a hose repeatedly across concrete can concentrate wear surprisingly quickly. Where compatible, spiral guarding can add protection to exposed sections of washdown hose.
Browse Washdown Guns when building or maintaining related washdown equipment.
Industrial Machinery
Even fixed plant creates movement through vibration, cylinders & reciprocating components. Hose runs near structural frames or moving assemblies can benefit from closer attention to external wear.
Product Selection Guide
Don't select spiral guard from the hose's nominal bore alone. The outside dimensions of the assembly being protected are an important part of choosing the appropriate guard.

Establish The Hose Outside Diameter
The hose itself provides the starting point. Determine the relevant outside diameter rather than assuming a guard size from the hose bore designation.
Decide What Needs Protecting
Is the concern concentrated around one abrasion point or spread across a longer hose run? Knowing the exposure area helps determine the length of guarding required.
Account For Hose Movement
Protection shouldn't prevent the hose from doing its job. Consider how the assembly moves throughout the machine's operating range & follow applicable hose, guard & equipment requirements.
Check Single-Hose vs Grouped-Hose Requirements
If several compatible lines are being protected together, consider the overall bundle dimensions, movement & installation requirements rather than sizing from one hose.
Inspect Before Covering
Don't hide questionable hose condition beneath new guarding. Examine the accessible hose first & address damage according to the equipment's maintenance requirements.
What Does The Wear Location Tell You?
The position of damaged guarding can help narrow down what the hose is contacting.

Replacing a worn guard without investigating why it wore there can miss the most useful clue. Read the wear pattern before discarding the old protection.
Spiral Guard Or Better Hose Routing?
Should every rubbing hose simply get a thicker protective layer? No. Spiral guard helps manage external abrasion, but persistent contact can also point to a routing, clearance or support issue.
Spiral Guard May Help When
► A compatible hose encounters unavoidable external contact
► Additional abrasion protection is required
► Adjacent hoses need suitable exterior separation
► A vulnerable section requires added shielding
Look Beyond The Guard When
► A hose is continually forced against a sharp structure
► The assembly is stretched during machine movement
► Bend conditions appear unsuitable
► A hose is being crushed
► The same guard location repeatedly wears through
► Existing hose damage is already visible
Protection & routing solve different parts of the problem. Good hose management considers both.
Expert Tips
Cycle The Machine In Your Inspection Thinking
One parked position rarely tells the whole story on mobile equipment. Hose clearance can change substantially as booms, cylinders, steering systems & attachments move.
Mark The Wear Position Before Removing Old Guard
That scuffed section is evidence. Note where it sits relative to brackets, clamps & neighbouring hoses before the old guarding is removed.
Measure The Assembly You Actually Have
A hose's nominal size doesn't necessarily tell you its outside diameter. Work from the relevant physical dimensions & individual guard specifications.
Keep Guarding From Hiding A Problem
Fresh protection should never become camouflage for a questionable hose. Inspect the underlying assembly before covering it.
Check Both Ends Of The Protected Section
Movement can cause protection to migrate away from the area that originally needed it. Include guard position in routine inspections.
Treat Repeat Damage As A Diagnostic Clue
If crews keep replacing protection in exactly the same place, investigate the environment around that point. Clearance, routing or another moving component may be contributing.
A Practical Mobile-Plant Example
Imagine a hydraulic line running along an excavator boom with plenty of clearance while the machine is parked. Nothing looks wrong during the initial walk-around.
Once the attachment curls inward, however, the hose moves towards a steel bracket. Over hundreds of operating cycles, the same section makes intermittent contact.
Eventually, the spiral guard develops a polished & visibly worn patch.
Rather than simply fitting another length & moving on, that wear location gives the technician somewhere specific to investigate: hose movement, bracket clearance, support position & the condition of the underlying assembly.
Crews operating machinery in harsh environments may find Quarry Crews Crusher Maintenance useful for broader equipment-maintenance considerations.
When Should Spiral Guard Be Checked?
Waiting until the guard has split apart defeats much of the value of visual inspection. Check protection as part of the equipment's applicable maintenance routine & give demanding applications appropriate attention.
Look for:
► Deep scuffing
► Cuts or splits
► Sections worn through
► Guard movement
► Exposed hose
► Changes in routing
► Hose-to-hose contact
► Damaged supports
► New contact with surrounding structures
Finding damage to the guard should trigger a look at what's underneath it. The condition of the protected hose ultimately determines whether the assembly remains suitable for service.
For seasonal equipment preparation, Spring Jobsite Prep Getting Your Gear Ready covers broader checks worth completing before workloads increase.
Before The Equipment Leaves The Workshop
New guarding deserves a final look in context, not just on the workbench. Review the accessible assembly before returning machinery to service.
Check where applicable:
► Guard position
► Hose clearance
► Routing through moving areas
► Nearby brackets & structures
► Hose-to-hose contact
► Fittings & supports
► Underlying hose condition
► Required machine movement
Hydraulic & pressurised systems can present serious hazards. Follow the isolation, inspection, installation & recommissioning procedures applicable to the equipment.
