Rislone Heavy Duty Hydraulic Seal Stop Leak 950ml

Use When You Notice…

• Oil weeping from cylinder glands or hose fittings: The formula reconditions aged seals, closing slow seeps without dismantling the cylinder.
• Frequent hydraulic fluid top-ups on tractors or loaders: Persistent fluid loss points to seal degradation — this addresses the root cause, not just the symptom.
• Lift arm slowly dropping under load: Worn seals allow internal pressure bypass; reconditioning restores holding force and productivity.
• Spongy or sluggish hydraulic response: Air ingestion through leaking seals reduces circuit efficiency — stopping the leak restores sharp, responsive control.
• Dust caking or oil staining around cylinder rods: An early warning that seals are drying out and need conditioning before full failure.

Key Benefits

• Seal Restoration: Revives elasticity in dried, hardened NBR and polyurethane seals common in Indian agricultural and construction equipment.
• Downtime Prevention: Keeps machines productive during critical harvest seasons and construction project deadlines when workshop downtime is most costly.
• Cost-Effective Repair: A cost-effective alternative to a full hydraulic cylinder reseal, which can cost ₹15,000–₹50,000 in parts and labour.
• Continuous Protection: Stays active in the fluid, providing ongoing seal conditioning and protection against India's extreme heat and dust.
• Precision-Safe Formula: Does not alter fluid viscosity or leave deposits that could clog sensitive hydraulic valves or spool passages.

The Technology Inside

Rislone Hydraulic Seal contains concentrated elastomer conditioners that penetrate aged seal material and restore molecular flexibility — reversing the hardening caused by heat cycling and oxidised fluid. The additive package also includes extreme-pressure lubricity agents that reduce metal-to-seal wear inside cylinder bores and rod glands. Unlike bulking agents used in inferior stop-leak products, this formula works at a chemical level and produces no particulate matter that could block precision metering orifices or load-sensing valves. It is fully miscible with ISO VG 46 and ISO VG 68 hydraulic oils — the two grades most widely used in Indian tractors and earthmoving equipment. The result is a reconditioned sealing surface that holds system pressure without bypassing fluid internally.

Dosage & Coverage

Add the recommended percentage of total reservoir volume as indicated on the bottle label chart — typically higher for a 50-litre tractor reservoir than for a smaller 10-litre excavator auxiliary circuit. The 950 ml bottle is sized to treat large commercial hydraulic systems in a single application. Check the fluid level after adding, operate the equipment normally, and monitor over several working days for improvement.

Compatibility

Safe to use with

• Mineral-oil-based hydraulic systems in tractors, JCBs, loaders and excavators.
• ISO VG 46 and ISO VG 68 hydraulic oils widely used across India.
• All major Indian and international equipment brands: Mahindra, John Deere, JCB, L&T Komatsu and CASE.
• Hydraulic jacks, workshop lifts, and industrial presses running on mineral hydraulic oil.

Not suitable for

• Brake hydraulic systems — use only brake-fluid-compatible products there.
• Systems using phosphate-ester or fire-resistant hydraulic fluids.
• Systems that specify water-glycol hydraulic fluid.

Why It Matters in India

On Indian construction sites and farms, hydraulic seal failure is among the top causes of machine downtime — made worse by summer temperatures exceeding 45°C, dust infiltration, and the wide variation in hydraulic jack oil quality available in local markets. Cheap substitute fluids accelerate seal degradation, leaving operators facing unplanned repair bills exactly when equipment is needed most. Rislone Hydraulic Seal protects hydraulic seals in Indian heat and dust, extending service intervals and reducing total ownership costs for operators of Mahindra tractors, JCB 3DX backhoe loaders, and similar equipment across the country.

How To Use

1. Check the hydraulic fluid level, condition, and confirm the system uses mineral-oil-based fluid.
2. Add the recommended amount directly into the hydraulic reservoir as per the label dosage chart.
3. Operate the equipment normally and monitor the leak area and fluid level over several working days.
4. Top up hydraulic fluid if the level drops below the minimum mark during the treatment period.

Safety Note: Always work on equipment that is lowered, depressurised and cooled before opening the reservoir cap. Wear gloves when handling hydraulic fluid 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 valves, load-sensing passages, or metering orifices when used at the recommended ratio. Operators can continue normal work cycles immediately after adding it.

Can I use it in any tractor or backhoe loader brand sold in India?

Yes — it is compatible with all major brands running mineral-oil hydraulic fluid, including Mahindra, John Deere, New Holland, JCB, L&T Komatsu and CASE. Always confirm your system does not use a specialty fluid before adding any additive.

How long does it take to see results?

Most operators notice a reduction in leakage within 3–7 days of normal operation as the conditioners restore seal elasticity gradually. Heavily degraded seals may take longer or may require a mechanical reseal if damage is too advanced.

Is this safe to use with adblue diesel engine equipment?

This product treats the hydraulic circuit only and does not interact with the engine, fuel system, or AdBlue diesel SCR system in any way. It is safe for use on modern BS6-compliant construction and farm equipment that uses AdBlue diesel emission systems alongside mineral-oil hydraulic circuits.
