Rislone 41812

Use When You Notice…

• Jack slowly drops under load: Leaking ram seals bleed pressure — the seal conditioner rebuilds the sealing surface so the jack holds its load safely.
• Jack fails to reach full extension: Degraded hydraulic 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 original dimensions.
• Spongy pump action or extra strokes needed to lift: Air ingress and thinned fluid reduce pump efficiency; correct-viscosity jack oil firms the action right away.
• Fluid appears dark, burnt, or contaminated: Oxidised fluid accelerates seal damage — drain and refill with fresh hydraulic car jack oil to protect internal components.

Key Benefits

• Full Lift Restored: Refilling with the correct hydraulic jack oil brings the ram back to its rated extension height immediately.
• Seal Conditioner Built In: Rejuvenates hardened or shrunken O-rings and ram seals — stops seepage without special tools or a workshop visit.
• Correct Viscosity: Formulated specifically for jack cylinders — not a generic substitute that risks seal swell or pump damage.
• Safety First: A jack that holds its load matters — this liquid restores the load-holding ability that a slow-dropping jack has lost.
• Workshop Economy: Revives ageing jacks used daily in tyre shops and roadside garages across India at a fraction of replacement cost.

The Technology Inside

Rislone 41812 is a mineral-base hydraulic fluid blended to the correct ISO viscosity grade for jack cylinder operation — not a repurposed power-steering or brake fluid. The seal-conditioning additive package uses controlled elastomer swelling agents that restore original dimensions to compressed or dried-out NBR and polyurethane ram seals, the same seal materials found in most workshop floor jacks and bottle jacks. Unlike over-the-counter jack oil near me options that use generic formulations, this product is engineered to maintain stable viscosity across the 10–60°C operating range common in Indian workshops — from cool winter mornings in North India to peak summer floors reaching 45°C in May. The result is consistent pump stiffness, reliable pressure retention, and extended seal service life without mechanical disassembly.

Dosage & Coverage

Lower the jack fully, remove the fill plug, and top off or fully refill with Rislone 41812 to the level marked inside the reservoir — most standard floor jacks require 250–500 ml and most bottle jacks 100–200 ml. After filling, bleed trapped air by pumping and releasing the jack several times before putting it back into service. One bottle is typically sufficient for a single jack refill; repeat treatment is rarely needed unless the jack is used under extremely heavy daily loads.

Compatibility

Safe to use with

• Standard hydraulic floor jacks (2T, 3T, 5T ratings common in Indian workshops)
• Bottle jacks and scissor jacks using mineral-base hydraulic jack oil
• Most OEM and aftermarket jack cylinders with NBR or polyurethane ram seals

Not suitable for

• Systems requiring brake fluid, power steering fluid, or synthetic hydraulic fluid
• Air-over-hydraulic or pneumatic jack systems
• Jacks with a broken pump mechanism or catastrophically failed internal seals requiring mechanical rebuild

Why It Matters in India

In Indian tyre shops, roadside puncture stalls, and small garages from Delhi to Coimbatore, a hydraulic floor jack works every single day — often in 42–48°C summer heat that degrades jack oil faster than in temperate climates. Dust-laden workshop floors contaminate the fluid, and infrequent maintenance means seals dry out long before the jack is inspected. A slow-dropping jack is a genuine safety hazard when it is holding a loaded truck or SUV. Rislone 41812 gives every mechanic and workshop owner an affordable, accessible way to make their jack safe and reliable again — no costly replacement, no downtime.

How To Use

1. Lower the jack completely to its minimum height and place it on a flat surface.
2. Locate and remove the fill plug — usually a rubber bung or threaded screw on the side.
3. Top off or fully refill with Rislone 41812 to the correct reservoir level.
4. Pump and release the jack several times to bleed air, then test under a safe load before normal use.

Safety Note: Never work under a vehicle supported only by a hydraulic jack — always use axle stands. Test the repaired jack with a light load before trusting it with full vehicle weight.

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 cannot reach full height, yes — the seal conditioner and correct-viscosity hydraulic car jack oil will typically restore normal operation. If the pump mechanism is mechanically broken or seals are catastrophically torn, a mechanical rebuild or replacement is needed instead.

How long does the stop-leak effect last?

Under normal workshop use, one treatment typically keeps the jack performing reliably for several months to a few years, depending on how often the jack is used and how worn the original seals were. Heavily used workshop jacks may benefit from an annual fluid check and top-up.

Is it safe to mix Rislone 41812 with the old jack oil already inside?

Yes — for a top-up this is fine, as Rislone 41812 is a mineral-base fluid compatible with most existing jack oils. For best results with a heavily contaminated or dark fluid, drain the old oil first before refilling with fresh product.

Is cash on delivery (COD) available when I order from naredi.in?

Yes, Cash on Delivery is available across India including Tier 2 and Tier 3 cities. Free delivery is included on all orders — no minimum order value required.

Can I use this in the scissor jack that came with my Maruti, Hyundai, or Tata vehicle?

Rislone 41812 is suitable for hydraulic scissor jacks that use mineral jack oil — check your jack's manual to confirm it is hydraulic rather than purely mechanical. Most OEM scissor jacks supplied with Indian passenger vehicles are mechanical screw-type jacks and do not use hydraulic fluid.
