Rislone 41812

Use When You Notice…

• Jack slowly drops under load: Internal seal bypass lets fluid escape; the seal conditioner swells and rejuvenates seals to hold pressure safely.
• Jack cannot reach full extension height: Low or contaminated hydraulic jack oil reduces lift travel; topping up restores full range of motion.
• Visible oil seepage around the ram or fill plug: Classic sign of deteriorated seals — the stop-leak chemistry targets this exact failure point.
• Pump feels spongy or needs extra strokes: Air trapped with low fluid causes this; refilling and bleeding with Rislone 41812 resolves both issues together.
• Jack unused for a long season: Stored jacks develop dried, shrunken seals; the conditioner rehydrates them without disassembly.

Key Benefits

• Full Lift Restored: Correct-viscosity jack oil ensures the ram travels its complete stroke, giving you safe, predictable lift every time.
• Built-In Stop Leak: Seal conditioner chemistry rejuvenates dried O-rings and ram seals without dismantling the jack.
• Purpose-Formulated Viscosity: Matched specifically to hydraulic jack cylinder requirements — generic oils can cause seal swell or premature failure.
• Cost-Effective Repair: Revive an old jack for a fraction of replacement cost — ideal for busy Indian tyre shops and roadside workshops.
• Safe Under Load: Restored seal integrity means the ram holds position under vehicle weight, preventing dangerous slow-drop incidents.

The Technology Inside

Rislone 41812 is a mineral-oil hydraulic fluid blended with proprietary seal conditioners engineered specifically for jack cylinder tolerances. The conditioner package works by gradually re-plasticising shrunken or hardened elastomer seals — restoring their original diameter and flexibility so they form a proper pressure boundary again. Unlike ATF or generic AW46 hydraulic oil sometimes used as substitutes, this formulation will not over-swell or chemically degrade the nitrile and polyurethane seals common in floor and bottle jacks. The result is restored system pressure, eliminated fluid bypass, and a jack that holds its lift height reliably under load.

Dosage & Coverage

Lower the jack fully, remove the fill plug, and top off or completely refill with Rislone Jack Oil & Stop Leak to the manufacturer-specified level. After filling, bleed trapped air by pumping and releasing the jack several times before returning it to service. For most standard floor and bottle jacks used in Indian workshops, one bottle is sufficient for a complete fluid change and seal treatment.

Compatibility

Safe to use with

• Standard hydraulic floor jacks (2-tonne, 3-tonne workshop type)
• Bottle jacks used for vehicle lifting and load support
• Scissor jacks with hydraulic assist mechanisms using mineral jack oil
• Most OEM and aftermarket jack brands common in Indian garages

Not suitable for

• Systems requiring brake fluid, power steering fluid, or synthetic hydraulic fluid
• Jacks with a broken pump mechanism or catastrophic internal seal failure
• Industrial hydraulic machinery requiring ISO VG-rated specialty fluids

Why It Matters in India

In Indian workshops — from busy tyre shops in Delhi to roadside mechanics in Tier 2 cities — floor jacks are used hard, serviced rarely, and stored in dusty, high-heat conditions where ambient temperatures reach 42–48°C in summer. This heat accelerates seal degradation and oil evaporation, causing jacks to drop dangerously under load. A slow-dropping jack is a genuine safety hazard; Rislone 41812 makes the old jack safe and reliable again at a fraction of replacement cost, which matters to every mechanic keeping a tight budget.

How To Use

1. Lower the jack fully and locate the fill plug (usually a rubber plug or screw on the side).
2. Remove the fill plug and top off or refill completely with Rislone 41812 to the correct level.
3. Replace the fill plug securely, then pump and release the jack several times to bleed trapped air.
4. Test lift operation under load before returning the jack to regular workshop service.

Safety Note: Never work under a vehicle supported only by a hydraulic jack. Always use axle stands once the vehicle is raised. Verify full lift restoration before relying on the jack for any repair work.

Frequently Asked Questions

Can Rislone 41812 fix a jack that completely fails to lift?

If the jack still builds some pressure but drops slowly or cannot reach full height, yes — this product is designed for exactly that scenario. If the pump mechanism is physically broken or seals have completely disintegrated, mechanical repair or jack replacement will be needed.

How long does the stop-leak effect last?

Under normal Indian workshop use, one treatment typically restores the jack for several months to years depending on usage frequency and original seal condition. Jacks used daily in high-heat environments may benefit from an annual fluid refresh.

Is this suitable for the imported floor jacks commonly found in Indian garages?

Yes — Rislone 41812 is compatible with most mineral-oil-based floor and bottle jacks regardless of brand or country of origin. If your jack's manual specifies mineral hydraulic jack oil, this product is appropriate.

Can I get this delivered to a Tier 2 or Tier 3 city with Cash on Delivery?

Absolutely. naredi.in offers free delivery across India with Cash on Delivery available at checkout. Most Tier 2 and Tier 3 locations are covered within 5–7 business days.

Is jack oil near me hard to find — is ordering online reliable?

Genuine Rislone products are difficult to source locally outside major metros, making naredi.in the most reliable option for authentic stock. Ordering online ensures you receive the correct formulation, not a generic substitute.
