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 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, robbing the system of pressure and slowing implement response times.

Key Benefits

• Restores Seal Elasticity: Reconditions dried, hardened O-rings and lip seals without mechanical disassembly, saving significant workshop labour costs.
• Reduces Costly Downtime: Keeps tractors, loaders and excavators productive during critical harvest seasons and construction project deadlines.
• Protects in Indian Conditions: Specially formulated to protect hydraulic seals in Indian heat and dust where standard fluids degrade seals faster.
• Cost-Effective Solution: A cost-effective alternative to full hydraulic fluid replacement or a ₹15,000–₹50,000 cylinder reseal job.
• Large-Volume Coverage: The 950 ml bottle treats the large reservoir volumes typical of commercial agricultural and construction equipment.

The Technology Inside

Rislone Hydraulic Seal Stop Leak contains a concentrated blend of seal conditioners and extreme-pressure lubricity additives engineered for high-pressure hydraulic circuits. The active seal-rejuvenation chemistry works by reversing the oxidation and heat-induced shrinkage that causes elastomeric seals — polyurethane lip seals, nitrile O-rings and polyacrylate rod seals — to lose their original profile and leak. Unlike older solvent-based stop-leak products, this formula does not swell seals indiscriminately; it restores them to their designed dimensional tolerance, maintaining precise spool-valve and metering-orifice clearances. The extreme-pressure additives also reduce metal-to-metal wear inside hydraulic pumps and motors, which is especially valuable where cheap or contaminated hydraulic jack oil in India has already accelerated internal wear. The result is a hydraulic circuit that holds rated working pressure, responds crisply and loses less fluid to bypass.

Dosage & Coverage

Add Rislone Hydraulic Seal Stop Leak directly to the hydraulic reservoir at the ratio specified on the label chart — the correct dose differs between a 50-litre tractor reservoir and a 10-litre excavator auxiliary circuit, so always check the chart before pouring. The 950 ml bottle is sized to treat the large-volume systems found in commercial agricultural and construction equipment in a single application. Check the fluid level after adding, operate the equipment normally for several working days and monitor the leak points; a second application is rarely required when used at the correct ratio.

Compatibility

Safe to use with

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

Not suitable for

• Brake hydraulic systems — use only brake-fluid-compatible products in braking circuits
• Systems using phosphate-ester or fire-resistant hydraulic fluids
• Systems requiring water-glycol hydraulic fluid
• Physically torn or cut seals and damaged cylinder bores — mechanical repair required first

Why It Matters in India

On Indian construction sites and farms, hydraulic systems endure summer ambient temperatures exceeding 45 °C, abrasive dust ingestion and continuous heavy-cycle loading that ages seals two to three times faster than in temperate climates. A JCB or excavator cylinder reseal can cost ₹15,000–₹50,000 in parts and workshop charges alone — not counting the day or more of lost machine time. Rislone Hydraulic Seal Stop Leak can delay or prevent that repair entirely, keeping the machine productive through critical kharif and rabi harvest windows or a project completion deadline. It is available through naredi.in with pan-India delivery, so rural operators and urban workshops alike can access it without sourcing delays.

How To Use

1. Check the hydraulic fluid level, type and cleanliness before adding any additive.
2. Consult the label dosage chart and pour the correct volume into the hydraulic reservoir.
3. Replace the reservoir cap, start the equipment and cycle all hydraulic functions for 10–15 minutes.
4. Monitor leak points and fluid level over the next several working days.

Safety Note: Always allow the hydraulic system to cool before opening the reservoir cap. Wear nitrile 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 valves, metering orifices or servo-valve spools when used at the recommended ratio. It is specifically designed to be particle-free and compatible with sensitive hydraulic control systems.

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, CASE, Escorts and TAFE. If your equipment uses mineral hydraulic oil, this product is suitable.

How long before I see results?

Most operators notice a measurable reduction in leakage within 3–7 working days as the seal conditioners gradually restore elastomer dimensions. Severe or long-standing leaks may take up to two weeks of normal operation to fully respond.

Is Cash on Delivery available for delivery across India?

Yes — naredi.in offers Cash on Delivery and free delivery pan-India, including to rural addresses in agricultural districts where this product is most in demand. Orders are typically dispatched within one business day.

Can this be mixed with the existing hydraulic oil already in the system?

Yes — simply add the correct dose directly to the existing hydraulic fluid in the reservoir without draining or flushing. The formula is fully miscible with ISO 46 and ISO 68 mineral hydraulic oils and will not cause cloudiness or sludge.
