Hydraulic Seal Stop Leak - Save ₹50,000 Repairs

Use When You Notice…

• Slow oil seep from cylinder glands or rod seals — the seal conditioners in this hydraulic leak sealant restore elasticity to dried-out seals, stopping the weep without physical replacement.
• Frequent hydraulic fluid top-ups in your tractor or loader — gradual fluid loss from micro-leaks is exactly what this heavy duty hydraulic stop leak additive is formulated to address.
• Lift arm or bucket dropping slowly under load — internal bypass caused by worn seals is reduced as the conditioners swell and reseat aged rubber.
• Visible puddles or staining under a JCB, excavator or hydraulic jack — suitable for hydraulic jacks, lifts and equipment used in Indian garages and workshops.
• New equipment showing premature seal wear — common when cheap or mismatched hydraulic jack oil is used, which is widespread in India's smaller workshops.

Key Benefits

• Seal Restoration: Restores flexibility to hardened rubber seals, stopping leaks in cylinders and hoses without dismantling — saving 8–10 hours of labour charges.
• Cost Saving: A single bottle at ₹2,100 can defer or prevent a hydraulic cylinder reseal costing ₹15,000–₹50,000 in parts and workshop fees.
• Protects in Indian Heat: Formulated to remain stable at 45°C+ ambient temperatures — protects hydraulic seals in Indian heat and dust far better than generic additives.
• No System Contamination: Particle-free formula will not clog precision spool valves, metering orifices or hydraulic filters.
• Ongoing Conditioning: Safe to leave in the reservoir permanently — acts as a cost-effective alternative to full hydraulic fluid replacement between scheduled services.
• Made in USA: Rislone has been trusted in American heavy equipment for 40+ years — now available through naredi.in with pan-India delivery.

The Technology Inside

Rislone Hydraulic Seal contains concentrated seal conditioners — primarily ester-based softening agents — that penetrate aged nitrile and polyurethane seals and restore their original elasticity. Unlike petroleum solvents that swell seals temporarily, these conditioners bond with the seal matrix for a lasting result. The formula also carries extreme-pressure (EP) lubricity additives that reduce metal-to-metal contact in high-pressure hydraulic circuits, lowering heat generation at pump faces and valve spools. Critically, the additive package is engineered to be shear-stable, meaning it will not break down under the high-frequency pressure cycles of a working excavator or tractor pump. The result is a hydraulic oil sealant that conditions without altering system viscosity beyond acceptable ISO tolerances.

Dosage & Coverage

Add Rislone Hydraulic Seal as a percentage of your total reservoir volume — refer to the dosage chart printed on the bottle label, which covers systems from 10-litre excavator auxiliary circuits to 50-litre tractor main reservoirs. The 950 ml bottle is well matched to the large reservoir capacities common on Indian farm tractors and backhoe loaders. Check fluid level after adding, operate equipment normally and monitor the leak point over several working days; a second application is rarely needed when used at the correct ratio.

Compatibility

Safe to use with

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

Not suitable for

• Brake hydraulic systems — use only dedicated brake fluid products.
• Systems using phosphate-ester or fire-resistant hydraulic fluids.
• Systems requiring water-glycol hydraulic fluid.
• Physically torn or cracked hoses and seals — those require mechanical replacement.

Why It Matters in India

On Indian construction sites and farms, hydraulic cylinder seal leaks are among the leading causes of machine downtime. Dust ingestion, extreme summer temperatures regularly crossing 45°C and the widespread use of substandard hydraulic jack oil all accelerate seal wear far faster than in moderate climates. A JCB or Mahindra tractor cylinder reseal during a harvest window or road-building contract can mean ₹15,000–₹50,000 in parts plus lost daily earnings of ₹5,000–₹15,000. Rislone Hydraulic Seal is a proven, immediate intervention that keeps the machine productive when stopping for workshop repairs is simply not an option.

How To Use

1. Check hydraulic fluid level, type and cleanliness before adding any additive.
2. Add the recommended quantity of Rislone Hydraulic Seal directly into the reservoir filler neck.
3. Operate the equipment through its normal work cycle for several hours to circulate the product.
4. Monitor the leak point and fluid level over the next two to three working days.

Safety Note: Always depressurise the hydraulic system before opening the reservoir cap. Wear gloves and eye protection when handling hydraulic fluids and additives.

Frequently Asked Questions

Will this affect my hydraulic pump or control valve performance?

No — the formula is engineered not to alter fluid viscosity beyond ISO tolerances and contains no solid particles that could clog precision spool valves or metering orifices. Used at the recommended dose ratio, pump output and valve response remain normal.

Is it compatible with all tractor and backhoe brands sold in India?

Yes — Rislone Hydraulic Seal is compatible with all major brands running mineral-oil hydraulic fluid, including Mahindra, John Deere, JCB, L&T Komatsu, CASE and ESCORTS. Always confirm your system does not use a speciality fire-resistant or water-glycol fluid before adding.

How quickly will the leak stop?

Most users see a significant reduction in seepage within one to two working shifts as the conditioners penetrate the seals. Complete sealing of slow weeps typically occurs within two to four days of normal equipment operation.

Can I use this in my workshop hydraulic jack or lift?

Yes — it is suitable for hydraulic jacks, lifts and equipment used in Indian garages and workshops running standard mineral hydraulic jack oil. It is not suitable for jacks using water-based or fire-resistant fluids.
