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 occurs.

Key Benefits

• Seal Restoration: Restores elasticity to hardened rubber seals, stopping leaks in cylinders and hose glands without mechanical repair.
• Reduced Downtime: Keeps farm and construction equipment productive during critical harvest or project phases instead of sitting in a workshop.
• Permanent Protection: Safe to leave in the hydraulic system indefinitely, providing continuous seal conditioning with every operating cycle.
• Cost Saving: A cost-effective alternative to full hydraulic seal replacement, which can cost ₹15,000–₹50,000 per cylinder on a JCB or excavator.
• Right Size for India: The 950 ml bottle treats large-reservoir machines common on Indian farms and construction sites.

The Technology Inside

Rislone Hydraulic Seal Stop Leak contains concentrated seal-conditioning esters and extreme-pressure lubricity additives formulated for high-pressure hydraulic circuits operating above 200 bar. These conditioners penetrate aged nitrile and polyurethane seals, restoring their original cross-section and flexibility without swelling them beyond tolerance. The additive package is particle-free, so it will not clog precision spool valves, load-sensing orifices or pilot circuits that are sensitive to contamination. It also carries a mild oxidation inhibitor that slows future seal degradation caused by heat cycling — a particular concern in India where ambient temperatures routinely exceed 45 °C on construction sites. The result is a hydraulic circuit that holds pressure, responds crisply and protects hydraulic seals in Indian heat and dust.

Dosage & Coverage

Add Rislone Hydraulic Seal at the percentage of total reservoir volume shown on the label chart — typically around 10–20% depending on system size. A single 950 ml bottle is well matched to large reservoirs of 5–10 litres, such as those found in excavator auxiliary circuits, while two bottles suit the 50-litre main reservoirs common on Indian farm tractors. Check the fluid level after adding, operate equipment normally, and monitor seal condition over several working days; a second application is rarely needed.

Compatibility

Safe to use with

• Mineral-oil-based hydraulic systems in tractors, JCBs, backhoe loaders and excavators
• ISO VG 46 and ISO VG 68 hydraulic oils widely used across India
• Mahindra, John Deere, Escorts, JCB, L&T Komatsu, CASE and BEML equipment
• Hydraulic jacks, workshop lifts, and agricultural implements used in Indian garages and workshops

Not suitable for

• Brake hydraulic circuits — use dedicated brake fluid products only
• Systems filled with phosphate-ester or fire-resistant hydraulic fluid
• Water-glycol hydraulic fluid systems

Why It Matters in India

On Indian construction sites and farms, hydraulic cylinder seal leaks are among the top causes of machine downtime, yet full cylinder reseals are expensive and slow. Hydraulic jack oil quality in India varies widely — cheap substitutes accelerate seal drying and cracking far sooner than OEM-grade fluid. Rislone Hydraulic Seal Stop Leak is specifically suited to conditions where dust ingestion, sustained high loads and extreme heat combine to age seals prematurely. Using it at the first sign of seepage can extend seal life through an entire crop season or construction contract phase.

How To Use

1. Check the hydraulic fluid level, type and cleanliness before adding any treatment.
2. Pour the recommended volume of Rislone Hydraulic Seal into the reservoir as per the label chart.
3. Replace the filler cap, start the equipment and operate all hydraulic functions through their full range.
4. Monitor fluid level and leak points over the next few working days and top up fluid if required.

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

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, spool passages or load-sensing orifices when used at the recommended ratio. Your hydraulic system will continue to operate within its designed pressure and flow parameters.

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

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

How quickly will it stop a leak?

Most slow seeps reduce noticeably within 24–48 hours of normal operation as the conditioners penetrate and restore the seals. Heavily degraded seals may take several days of operation; if the leak does not reduce after one week, a mechanical seal replacement is likely required.

Is Cash on Delivery available for this product?

Yes — naredi.in offers Cash on Delivery across India, so you can order without a card or online payment. Free delivery is also included on this product.

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

Yes — it is suitable for hydraulic jacks, lifts, and equipment used in Indian garages and workshops running mineral-oil jack fluid. It is not suitable for brake systems or any jack filled with water-glycol fluid.
