Hose Spring Cover — SS304 Protection for Lubrication Lines
Hose protection covers (spring-wound guards) shield centralized lubrication hose and tubing from abrasion, puncture, hot surfaces, and impact in construction, mining, and industrial plants. IsoHiTech supplies 304 stainless steel spring covers in bore sizes for common grease and oil line diameters: 4 mm, 6 mm, 8 mm, 10 mm, and 12 mm.
Install the spring over exposed runs between the pump or divider and the bearing—especially where lines cross steel edges, rub against chassis rails, or pass near exhaust components. The cover adds a sacrificial layer so the inner pressure hose keeps integrity under vibration and debris contact.
Pair with lubrication pipe and hose, hose ends and studs, pipe clips, and progressive systems on mobile FS pumps or fixed grease pump skids.

- Intro
Why Protect Lubrication Hose?
Small-diameter high-pressure grease lines fail quietly when outer jackets wear through on sharp brackets or vibrating frames. A pinhole leak loses pressure, starves downstream bearings, and contaminates the machine with grease spray. Spring covers extend hose life without rigid armor that prevents bending.
Where to Install Spring Covers
- Chassis rails and loader booms where hose contacts steel
- Near pivot pins, articulation joints, and track rollers
- Zones with weld spatter, gravel impact, or fork-truck traffic
- Short spans before hose-end fittings at the bearing nipple
Selection by Line Size
Choose cover bore to match hose OD (not only nominal line size)—spring ID should slide over the hose with slight clearance for movement. For bundled runs, protect each hose individually or route with multi-tube clamps plus individual covers on exposed legs.
Installation Tips
- Slide spring over hose before crimping end fittings when possible.
- Overlap cover past sharp edges by at least 50 mm on each side.
- Secure with clips at both ends so cover does not walk off under vibration.
- Inspect covers during PM—replace when wire is flattened or ends unravel.
A spring-wound stainless guard that fits over grease or oil hose to protect the outer jacket from abrasion, punctures, and heat splash—keeping centralized lubrication lines pressure-tight on mobile and fixed equipment.
SS304 spring covers for nominal line sizes 4, 6, 8, 10, and 12 mm. Confirm against your hose OD before ordering.
This page covers centralized lubrication hose and tubing (grease/oil metering systems). The same spring guard concept applies to small hydraulic lines, but pressure rating and hose spec must match your circuit.
Route away from pinch points, clip every 300–500 mm, add spring cover on exposed spans crossing steel, and use protected hose ends at fittings. Pair with an automatic pump such as the FS grease pump for progressive systems.
Yes if fittings allow—split or openable guards may be required on some builds. Best practice is to install spring before end fittings on new assemblies.
Check at each lubrication PM cycle. Replace covers with flattened coils, broken wire, or migration off the hose end.
