Rislone 41812

Use When You Notice…

• Jack slowly drops under load: Leaking ram seals bleed pressure — the built-in seal conditioner rebuilds the sealing surface so the jack holds its load safely.
• Jack fails to reach full extension height: Degraded hydraulic car jack oil starves the cylinder; a correct refill restores full rated travel immediately.
• Visible oil seepage around the ram or fill plug: Active seal leaks are the most common jack failure — this formula swells seals back to their original dimensions.
• Spongy pump action or extra strokes needed to lift: Air ingress and thinned fluid reduce pump efficiency; correct-viscosity hydraulic jack oil firms the action right away.
• Fluid appears dark, burnt, or contaminated: Oxidised fluid accelerates seal damage — drain and refill with fresh Jack Oil & Stop Leak to protect internal components.

Key Benefits

• Full Lift Restored: Replenishes correct fluid volume so the jack reaches its rated extension height on every pump stroke.
• Seal Conditioner Built In: Rejuvenates hardened or shrunken ram seals, stopping seepage without dismantling the jack.
• Correct Viscosity: Formulated precisely for hydraulic jack cylinders — not a generic substitute that risks seal swell or premature wear.
• Cost-Effective Repair: Revives aging jacks for a fraction of replacement cost — ideal for tyre shops, roadside service bays, and home garages across India.
• Heat & Dust Stable: Performs reliably in Indian workshop conditions where ambient temperatures regularly exceed 42°C and dust contamination is high.

The Technology Inside

Rislone 41812 is a premium mineral-base hydraulic fluid blended to the exact ISO viscosity grade required by jack cylinders — neither too thin to hold pressure nor too thick to flow freely through narrow pump ports. The seal-conditioning additive package works by permeating elastomer seals, restoring their original pliability and cross-sectional geometry to stop ram weepage at its source. Unlike ATF or engine oil used as quick substitutes, this dedicated hydraulic jack oil will not cause incompatible seal swell that accelerates long-term damage. The oxidation inhibitors in the formulation slow fluid degradation, which is especially valuable in high-temperature Indian workshops where fluid life is shortened by ambient heat. Together, these elements deliver restored pump efficiency, safer load-holding, and extended service intervals in a single product.

Dosage & Coverage

Lower the jack fully, locate the fill plug (rubber bung or threaded screw), and top off or fully refill with Rislone 41812 to the manufacturer's specified level — most floor and bottle jacks require between 150 ml and 500 ml depending on capacity. After filling, bleed trapped air by pumping and releasing the jack several times before returning it to service. For heavily contaminated fluid, drain the old oil completely before refilling for best results.

Compatibility

Safe to use with

• Hydraulic floor jacks (2-tonne, 3-tonne, and heavy-duty variants)
• Bottle jacks used in tyre shops and roadside service bays
• Scissor jacks and low-profile racing jacks using mineral hydraulic jack oil
• Most OEM and aftermarket jacks specifying mineral-base hydraulic fluid

Not suitable for

• Systems requiring brake fluid, power steering fluid, or synthetic hydraulic oil
• Jacks with catastrophic internal pump failure requiring mechanical repair
• Air-over-hydraulic or electric hydraulic lift systems with proprietary fluids

Why It Matters in India

In India, workshop and roadside floor jacks are worked hard — lifting heavy-laden trucks, SUVs, and commercial vehicles day after day — and are rarely serviced until they fail. Indian summers push workshop temperatures to 42–48°C, accelerating seal degradation and fluid oxidation far faster than in temperate climates. A slow-dropping jack is a genuine safety hazard for any mechanic working beneath a vehicle, and replacing an entire jack is an unnecessary expense when the seals are the only worn part. Rislone 41812 is the practical, affordable solution trusted by tyre shops and service bays from Delhi to Chennai.

How To Use

1. Lower the jack completely and place it on a stable, level surface.
2. Locate and remove the fill plug — usually a rubber bung or small screw.
3. Top off or refill with Rislone 41812 to the correct level per the jack's manual.
4. Pump and release the jack several times to bleed air, then refit the fill plug.

Safety Note: Always test the jack under a safe load before using it to support a vehicle — never work under any vehicle supported only by a hydraulic jack without additional axle stands in place.

Frequently Asked Questions

Can this fix a jack that completely fails to lift anything?

If the jack still builds some pressure but drops slowly or fails to reach full height, yes — the seal conditioner will typically restore performance within a few pump cycles. If the pump mechanism itself is mechanically broken or seals are completely destroyed, physical repair or replacement will be necessary.

How long does the stop-leak effect last?

Under normal workshop use, a single treatment typically restores reliable performance for several months to years, depending on usage frequency and the original extent of seal wear. Periodic fluid checks every six months are recommended for jacks in daily commercial use.

Is this safe for the scissor jack that came with my Maruti or Hyundai?

Yes — scissor jacks using mineral-base hydraulic fluid are compatible with Rislone 41812. Always confirm your jack's fluid specification in the owner's manual before adding any fluid.

Is Cash on Delivery available when I order from naredi.in?

Yes, COD is available across India and free delivery is included on all orders. You can also reach the naredi.in team on WhatsApp at +91 93112 11157 for order support Monday to Saturday.

Can I mix this with the old fluid already in my jack?

Yes, topping up into existing mineral-base fluid is fine for mild cases. For best results where fluid is dark or contaminated, drain the old fluid fully before refilling with fresh Rislone 41812.
