ESCO Yellow Jackit 20 Ton Air/Manual Bottle Jack for Heavy-Duty Tire Service
The ESCO Yellow Jackit 20-ton bottle jack is purpose-built for commercial tire service, delivering reliable air-hydraulic and manual lifting capability for trucks, buses, tractors, and farm equipment. With a welded base and cylinder design for maximum strength, chrome-plated piston and ram for rust resistance, and height range from 9.625" to 18.75", this jack provides the durability and performance professional technicians demand.

ESCO Yellow Jackit Features
Air-Hydraulic and Manual Operation
Switch between air operation at 100-145 PSI for quick, effortless lifting or use manual backup when compressed air is unavailable. This dual-mode design ensures maximum flexibility in any service environment, whether you're working at a busy tire shop or remote job site.
Welded Base and Cylinder Construction
The welded design creates a single unified structure that eliminates potential leak points and provides exceptional structural rigidity. This engineering choice delivers superior strength and reliability compared to bolted assemblies, extending the service life of the jack.
Chrome-Plated Pump and Ram
Rust-resistant chrome plating on all critical surfaces protects against corrosion and oxidation. The glossy finish also simplifies cleaning and maintenance, keeping your equipment looking professional while preserving function through years of heavy use.
Height Adjustment and Descent Control
The extension screw mechanism adds up to 9.125 inches of vertical adjustment (from minimum 9.625" to maximum 18.75"), accommodating a wide range of vehicle suspension heights and service needs. Return springs enable controlled, faster descent for improved workflow efficiency.
Compact, Portable Base Design
With a footprint of just 7" x 4.5" and total weight of 35 lbs, the Yellow Jackit fits into tight shop spaces and stores easily in service vehicles. The compact base delivers excellent stability during lifting while remaining light enough for single-person handling.
4-Foot Reinforced Hose
The included 48-inch (4 ft) hose provides ample reach for connecting to air sources or auxiliary hydraulic equipment. Reinforced construction resists kinking and damage, ensuring reliable performance over multiple work seasons.

ESCO Yellow Jackit Installation Requirements
Air Supply Connection
Pressure Range: 100-145 PSI. Connect to a regulated shop air line with appropriate quick-disconnect fittings. Ensure air supply is clean and dry to prevent corrosion inside the hydraulic system. Install an air filter-regulator-lubricator (FRL) unit upstream if your shop compressor lacks adequate filtration.
Hose and Connection Routing
Hose Length: 4 feet (48 inches) included. Route hoses away from hot surfaces, sharp edges, and direct vehicle traffic to prevent damage. Secure hoses with cable ties or clamps to prevent tripping hazards and kinking. Check hose connections monthly for weeping or leaks.
Surface and Placement Requirements
Work Surface: Place the jack on level, solid concrete or steel work surfaces only. Never use on gravel, asphalt, or soft ground, as the concentrated load may cause the base to shift or sink, creating a safety hazard. The compact 7" x 4.5" base requires precise placement for stability.
Pre-Operation Inspection
Before each use, inspect the welded base for cracks, the hose for cuts or leaks, and the piston rod for smooth operation. Verify that the extension screw operates freely. Check that all connection points are tight and secure. Manual operation should be tested if air supply will not be available.

ESCO Yellow Jackit FAQ
What is the maximum lifting capacity of the ESCO Yellow Jackit Model 10446?
The Model 10446 has a rated lifting capacity of 20 tons (40,000 lbs). This capacity applies to both air-hydraulic and manual operation modes. Never exceed this limit or use the jack for loads heavier than specified, as overloading voids the warranty and creates serious safety hazards. Always verify the weight of the vehicle or load before use.
What is the difference between the Model 10446 (welded base) and Model 10450 (screw-on base)?
Both models have identical 20-ton capacity and core specifications. The Model 10446 features a welded base creating a permanent, rigid structure with no leak points. The Model 10450 offers a screw-on base that can be removed for storage or replacement. The Model 10446 (welded) is more commonly used in tire shops, while the screw-on Model 10450 is preferred by field technicians who move equipment frequently between job sites.
What air pressure range is required to operate the Yellow Jackit?
The Yellow Jackit operates on compressed air at 100-145 PSI. Shop air must be regulated to stay within this range for safe, reliable operation. Operating below 100 PSI may result in insufficient lifting force; exceeding 145 PSI stresses the internal hydraulic system and voids warranty coverage. Use a regulated air line with a pressure gauge to verify compliance before use.
Can the Yellow Jackit be used without a compressed air supply?
Yes. The Yellow Jackit includes manual operation capability via the extension screw, allowing you to lift and lower loads manually when air is unavailable. Manual operation is slower but provides a reliable backup in field service situations. Some technicians use manual mode as a safety feature when working alone on critical lifts.
What is the height adjustment range of Model 10446?
The Model 10446 extends from a minimum height of 9.625 inches (245 mm) to a maximum height of 18.75 inches (476 mm), providing a total adjustment range of 9.125 inches (231 mm). This range accommodates most vehicle undercarriage heights for tire service. If you need lower or higher reach, ESCO offers the Model 10399 (shorty, min 5.83") and Model 10858 (tall, max 20.875").
How much does the ESCO Yellow Jackit weigh, and can one person handle it?
The Model 10446 weighs 35 lbs (16 kg), making it light enough for most single-person handling and storage. The compact 7" x 4.5" base fits into service vehicles, shop storage racks, and tight spaces. However, when used under load, ensure you have stable footing and follow all safety procedures for positioning and lowering heavy vehicles.
What does the included 4-foot hose connect to?
The 4-foot (48-inch) hose connects from your shop air supply to the pneumatic inlet valve on the jack. The hose should terminate in a quick-disconnect fitting matching your shop's air line standard (typically 3/8" NPT). Always verify hose connections before operation and check monthly for leaks, kinks, or damage that might compromise air supply.
Is the ESCO Yellow Jackit suitable for use at a tire shop?
Yes. The Yellow Jackit is specifically engineered for professional tire service shops. Its dual air-hydraulic and manual capability, compact footprint, and welded durability make it ideal for busy shops needing supplementary lifting stations. Many shops use multiple Yellow Jackits positioned around the service bay to speed tire changes and multi-vehicle workflows.
How should I maintain the ESCO Yellow Jackit to extend its life?
Maintain your Yellow Jackit by keeping the welded base and chrome piston clean and dry, regularly inspecting the hose for cracks or leaks, ensuring all connection points remain tight, testing extension screw operation before each use, and verifying air pressure stays within 100-145 PSI range. Store the jack in a dry location when not in use, and drain the internal hydraulic system before extended storage periods.
What warranty coverage comes with the ESCO Yellow Jackit?
The Yellow Jackit includes a limited lifetime warranty on the welded base and cylinder when registered at www.esco.net/warranty within 30 days of purchase. One-year coverage applies to pump, seals, and hose. The warranty covers defects in materials and workmanship under normal use but excludes wear, misuse, damage from neglect, and operation outside specified limits.
Can I use the Yellow Jackit outdoors or in extreme temperatures?
The Yellow Jackit is designed for indoor shop environments. Extended outdoor use or storage in extreme heat, cold, or wet conditions may accelerate corrosion and degrade hydraulic fluid performance, even with the chrome-plated protection. If you must use the jack outdoors, store it in a protective cover and inspect it more frequently for corrosion or fluid degradation.
Where can I order replacement parts or accessories for the ESCO Yellow Jackit?
ESCO offers replacement hoses, hydraulic fluid, pump seals, and quick-disconnect fittings through authorized distributors including Garage Supply Guys. You can also contact ESCO directly at www.esco.net or call their distributor network for hard-to-find parts. Always use genuine ESCO replacement parts to maintain warranty coverage and ensure safe operation.
