Rislone 41812 – Hydraulic Jack Oil + Stop Leak, 370ml

Use When You Notice…

• Jack slowly drops under load: Leaking ram seals bleed pressure — this formula conditions seals and restores hold.
• Fails to reach full extension height: Low or degraded fluid reduces lift travel; a refill with the correct jack oil fixes this immediately.
• Visible oil seepage near the ram or fill plug: Seal conditioner swells and reconditions dried seals to stop seepage at the source.
• Spongy pump action or extra strokes needed to lift: Air intrusion and fluid breakdown cause spongy response — fresh fluid and air bleeding restore crisp operation.
• Jack feels stiff or sluggish in cold mornings: Correct-viscosity fluid flows freely even after cool nights in hilly or northern Indian regions.

Key Benefits

• Stops Active Leaks: Built-in seal conditioner halts fluid loss around ram seals, preventing dangerous mid-lift drop.
• Restores Full Lift Capacity: Returns sluggish jacks to their rated lifting height — saving thousands of rupees on replacements.
• Correct Viscosity for Jack Cylinders: Engineered specifically as hydraulic jack oil, not a repurposed generic fluid that can damage seals over time.
• Climate Resilient: Performs reliably from Rajasthan's peak summer heat to Kerala's monsoon humidity without thinning or thickening.
• Oxidation Resistant: Outlasts cheap jack oil available in local Indian markets, extending service intervals significantly.
• No Special Tools Needed: Single-pour application; results are visible within minutes of pumping the handle.

The Technology Inside

Rislone 41812 is a mineral-oil based hydraulic fluid blended to the precise ISO viscosity grade required by jack cylinder circuits. Unlike workshop-grade AW46 or generic hydraulic oils, this formulation includes proprietary seal conditioning agents that penetrate and re-swell elastomer seals suffering from heat-induced shrinkage or oxidation hardening. The anti-oxidant additive package inhibits varnish formation inside the cylinder bore — a common failure mode when cheap substitutes are used in high-cycle workshop jacks. Foam suppressants reduce air entrainment, which is the primary cause of spongy pump action and inconsistent lift height. The result is restored volumetric efficiency and a sealed, reliable hydraulic circuit.

Dosage & Coverage

One 370 ml bottle is sufficient to fully refill most standard floor jacks and bottle jacks rated up to 3 tonnes, which typically hold 200–350 ml of fluid. For larger 5-tonne floor jacks, two bottles may be required. Under normal workshop use, fluid should be inspected annually and topped up as needed — one treatment commonly restores performance for several months to years depending on jack condition.

Compatibility

Safe to use with

• Most hydraulic floor jacks (1.5T, 2T, 3T, 5T ratings common in Indian workshops)
• Bottle jacks used in roadside tyre shops and commercial vehicle servicing
• Scissor jacks with hydraulic assist mechanisms
• Hydraulic hoists and small shop press cylinders using mineral jack oil

Not suitable for

• Systems requiring DOT brake fluid or power steering fluid
• Synthetic or bio-hydraulic fluid systems
• Jacks with broken pump mechanisms or severely damaged internal components — mechanical repair is needed first
• Industrial hydraulic circuits requiring high-pressure rated fluids above jack-circuit specifications

Why It Matters in India

In Indian tyre shops, dhabas, and roadside garages, floor jacks are used dozens of times daily under heavy commercial vehicles — Tata Ace, Ashok Leyland trucks, Mahindra tractors — with minimal servicing. Cheap local jack oil or wrong-viscosity substitutes accelerate seal wear and create genuine safety hazards when a loaded vehicle drops unexpectedly. Rislone 41812 is suitable for hydraulic jacks, lifts, and equipment used in Indian garages and workshops operating under extreme heat, dust, and heavy-load cycles. Replacing a neglected jack costs ₹3,000–₹15,000; a 370 ml bottle costs a fraction of that.

How To Use

1. Lower the jack fully and locate the fill plug — usually a rubber bung or slotted screw on the reservoir.
2. Remove the plug and top off or fully refill with Rislone Jack Oil & Stop Leak to the marked level.
3. Replace the fill plug securely and pump the handle 10–15 times to circulate fresh fluid.
4. Bleed trapped air by cycling the jack fully up and down 2–3 times before returning to service.

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

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 won't reach full height, yes — the seal conditioner and fresh fluid will typically restore function. If the pump mechanism is mechanically broken or a major internal seal has sheared completely, mechanical repair or replacement is needed before adding any fluid.

How long does the stop-leak effect last?

Under normal workshop use, one treatment typically restores the jack for several months to a few years depending on usage frequency and original seal condition. Jacks used dozens of times daily in busy tyre shops may need a top-up annually; garage jacks used occasionally can last much longer.

Is this safe to use with jacks servicing BS6 vehicles?

Yes — this is a jack oil, not an engine or exhaust fluid, so BS6 emission compliance of the vehicle being lifted is not relevant. It works safely with any vehicle regardless of fuel type or emission norm, including BS6 diesel and petrol vehicles.

Is Rislone 41812 available with Cash on Delivery across India?

Yes — naredi.in offers Cash on Delivery and free delivery across India, including Tier 2 and Tier 3 cities. Orders are dispatched promptly and tracking is provided via WhatsApp or email.

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

Yes, topping up into existing mineral jack oil is acceptable and safe. For best results — especially if the old fluid is dark, contaminated, or has been in service for years — drain the old fluid completely before refilling with Rislone 41812.
