Rislone Heavy Duty Hydraulic Seal Stop Leak 950ml

Use When You Notice…

• Slow seep from cylinder glands or hose fittings: Seal conditioners restore elasticity to shrunken O-rings and lip seals before a minor seep becomes a costly strip-down repair.
• Frequent hydraulic fluid top-ups on your tractor or loader: Unaccounted fluid loss points to slow seal leakage — this product addresses the root cause, not just the symptom.
• Lift arm slowly drooping under load: Internal bypass through degraded seals causes pressure bleed-down; reconditioned seals restore full holding pressure.
• Visible oil staining beneath a parked JCB or excavator: Surface staining indicates ongoing seal weep that will worsen over a full work season if left untreated.
• Sluggish or spongy hydraulic response: Worn seals allow internal fluid bypass, reducing circuit efficiency and response speed across all functions.

Key Benefits

• Seal Restoration: Reconditions aged and hardened hydraulic seals to stop active leaks without mechanical disassembly.
• Downtime Reduction: Keeps tractors, loaders and excavators productive during critical harvest or construction project phases.
• Cost Saving: A JCB cylinder reseal can cost ₹15,000–₹50,000 in India — this product can delay or prevent that expense entirely.
• Continuous Protection: Safe for long-term use in the system, providing ongoing seal conditioning between service intervals.
• Large-System Coverage: The 950 ml volume is sized for the large reservoirs common in Indian agricultural and construction machinery.
• Indian Conditions Ready: Protects hydraulic seals in Indian heat and dust where seal degradation occurs faster than in temperate climates.

The Technology Inside

Rislone Hydraulic Seal contains concentrated seal conditioner chemistry that reverses the oxidative hardening and shrinkage affecting nitrile and polyurethane lip seals over time. Extreme-pressure lubricity additives reduce metal-to-metal friction in hydraulic pumps and spool valves, lowering the operating temperatures that accelerate seal ageing in Indian summer conditions. The formula is engineered to be non-particulate — it will not form deposits that could block precision metering orifices or hydraulic control valves. Unlike cheap seal-swell compounds, it works by chemical reconditioning rather than forced expansion, so seals return to their designed dimensional tolerances rather than being over-pressurised and split.

Dosage & Coverage

Add Rislone Hydraulic Seal to the hydraulic reservoir at the ratio specified on the label chart, which varies between large 50-litre tractor reservoirs and smaller 10-litre excavator auxiliary circuits. One 950 ml bottle is a cost-effective alternative to full hydraulic fluid replacement and is sufficient for most single-machine treatments. Check fluid level after adding, operate equipment normally, and monitor for improvement over several working days.

Compatibility

Safe to use with

• Mineral-oil-based hydraulic systems in tractors, JCBs, backhoe loaders and excavators
• ISO 46 and ISO 68 hydraulic oils commonly used across India
• All major Indian and imported brands: Mahindra, John Deere, JCB, L&T Komatsu and CASE
• Hydraulic jacks, workshop lifts and industrial press equipment

Not suitable for

• Brake hydraulic systems — never add to brake fluid circuits
• Phosphate-ester or fire-resistant hydraulic fluids
• Systems specified for water-glycol hydraulic fluid
• Physically torn or cut seals and hoses — a mechanical repair is required first

Why It Matters in India

On Indian construction sites and farms, hydraulic systems endure 45°C+ ambient temperatures, fine silica dust ingestion and continuous heavy-load cycles that age seals far faster than manufacturers' standard ratings assume. Hydraulic jack oil quality in India varies widely — cheap substitutes accelerate seal hardening and leave equipment vulnerable to sudden pressure loss. Rislone Hydraulic Seal provides a practical, workshop-ready solution that protects hydraulic seals in Indian heat and dust without requiring specialist tools or a full fluid drain.

How To Use

1. Check hydraulic fluid level, type and condition before adding any treatment.
2. Add the recommended amount of Rislone Hydraulic Seal directly to the reservoir.
3. Operate equipment normally and monitor the leak area over several working days.
4. Top up hydraulic fluid to the correct level if required after treatment.

Safety Note: Always add to a cool, depressurised reservoir. Wear gloves and eye protection when handling hydraulic additives.

Frequently Asked Questions

Will this affect hydraulic pump or valve performance?

No — the formula does not significantly alter fluid viscosity and will not clog precision spool valves or metering orifices when used at the recommended ratio. Most operators notice improved response and reduced noise rather than any negative change.

Can it be used in tractors and backhoe loaders of all brands?

Yes — it is compatible with all major brands operating on mineral-oil hydraulic fluid, including Mahindra, John Deere, JCB, L&T Komatsu and CASE. If your machine uses a specialist OEM fluid, check the fluid type against the compatibility list above.

How quickly will I see results?

Most users notice reduced leakage within 1–4 days of normal operation as the seal conditioners absorb into aged seals. Severe hardening may take slightly longer; continued improvement is typically seen over the first full week of use.

Is Cash on Delivery available for delivery across India?

Yes — naredi.in offers free delivery across India with Cash on Delivery available at checkout. Orders are dispatched promptly and tracked from our warehouse to your location.

Can I use this as a preventive treatment, not just for active leaks?

Absolutely — adding Rislone Hydraulic Seal at service intervals conditions seals before hardening progresses to active leakage, making it an excellent preventive maintenance addition for any high-hour machine.
