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 dried-out rubber, closing micro-gaps before a full reseal is needed.
• Frequent hydraulic fluid top-ups on your tractor or loader: Persistent small losses add up fast — this product arrests the source rather than masking it.
• Lift arm that slowly drops under load: Internal bypass caused by worn seals loses pressure; conditioning the seals restores holding force.
• Oil film or staining around excavator arm pivot points: Early-stage seal weep responds well to a conditioning treatment before expensive cylinder removal.
• Hydraulic jack that won't hold its raised position: Ideal for hydraulic jacks and workshop lifts where seal dryout is the root cause of slow descent.

Key Benefits

• Seal Restoration: Revives aged, hardened seals in high-pressure hydraulic circuits — often eliminating a ₹15,000–₹50,000 cylinder reseal job.
• Protects Hydraulic Seals in Indian Heat and Dust: Extreme-pressure additives maintain a protective film even at peak summer operating temperatures.
• Zero Downtime Treatment: Add to the reservoir and continue operating — no system drain, no disassembly, no workshop idle time.
• Cost-Effective Alternative to Full Fluid Replacement: One 950 ml bottle treats most tractor and loader reservoirs at a fraction of replacement fluid cost.
• Valve-Safe Formula: Does not create sludge or particles that could block precision spool valves or metering orifices.

The Technology Inside

Rislone Hydraulic Seal contains concentrated seal-conditioning polymers that penetrate aged rubber and polyurethane seal materials, restoring their original elasticity and cross-sectional diameter. This seal rejuvenation chemistry works alongside extreme-pressure lubricity additives that reduce metal-to-metal contact inside hydraulic pump bores and spool valve lands. Unlike liquid wrench or filler-type sealants, this formula does not alter fluid viscosity beyond acceptable ISO tolerances, so pump efficiency and system response remain unaffected. The conditioners remain active in the fluid for extended service intervals, providing ongoing protection — particularly valuable in systems where cheap or variable-quality hydraulic oil substitutes have accelerated seal wear.

Dosage & Coverage

Add the recommended percentage of total reservoir volume as indicated on the label dosage chart — typically one 950 ml bottle treats reservoirs in the 20–50 litre range common in Indian tractors and backhoe loaders. For smaller auxiliary circuits such as a 10-litre excavator attachment circuit, use proportionally less. Check the fluid level after addition, operate equipment normally for several working days, and monitor leak points for improvement.

Compatibility

Safe to use with

• Mineral-oil-based hydraulic systems in tractors, JCBs, loaders and excavators
• ISO 46 and ISO 68 hydraulic oils widely used across India
• Hydraulic jacks, workshop lifts, and tipping body systems
• All major brands: Mahindra, John Deere, JCB, L&T Komatsu, CASE, Escorts

Not suitable for

• Brake hydraulic systems — use only brake-specific products there
• Phosphate-ester or fire-resistant hydraulic fluids
• Systems requiring water-glycol hydraulic fluid

Why It Matters in India

On Indian construction sites and farms, hydraulic cylinder seal leaks are among the leading causes of machine downtime, especially during summer when temperatures routinely exceed 42 °C and accelerate seal hardening. A JCB cylinder reseal can cost ₹15,000–₹50,000 in parts and workshop charges — unaffordable mid-harvest or mid-project. Because hydraulic jack oil quality in India varies widely and cheap substitutes are common, seals degrade faster than manufacturers' service schedules anticipate. Rislone Hydraulic Seal is a practical, cost-effective intervention that keeps machines productive when it matters most.

How To Use

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

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

Frequently Asked Questions

Will this affect hydraulic pump or valve performance?

No — the formula does not alter fluid viscosity significantly and will not clog precision valves or metering orifices when used at the recommended ratio. Your system response and pump flow remain normal throughout treatment.

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

Yes — it works with all major brands running mineral-oil hydraulic fluid, including Mahindra, John Deere, JCB, L&T Komatsu, CASE and Escorts. If your machine uses standard ISO 46 or ISO 68 oil, this product is compatible.

How quickly will I see results?

Most users notice reduced leaking within 100–200 hours of operation as seals re-swell and condition. Severe or physically torn seals require mechanical repair — this product addresses seal hardening and micro-gap leaks, not ruptures.

Is Cash on Delivery available and how fast is delivery?

Yes — naredi.in offers Cash on Delivery across India with free shipping. Most orders reach metro cities in 3–5 days and Tier-2 towns within 5–7 days.

Can I use this in a workshop hydraulic lift or floor jack?

Absolutely — it is suitable for hydraulic jacks, lifts, and equipment used in Indian garages and workshops. It is one of the most practical uses for this product given how frequently workshop jack seals dry out.
