Dualco High Pressure Hydraulic Grease Guns (11000 Series)
The Dualco 11000 Series hydraulic grease guns are engineered for high-pressure valve lubrication in demanding industrial environments. Rated up to 10,000 PSI, these tools meet the requirements of oil and gas operations, refineries, chemical plants, and processing facilities where standard grease guns fall short.
High-Pressure Performance
High-pressure applications demand equipment capable of delivering viscous lubricants, sealants, and packings through valve fittings under controlled pressure. The 11000 Series meets these needs with a design that handles thick materials and operates reliably across temperatures and positions common to field maintenance work.
High Pressure Grease Gun Models
The 11000 Series includes three primary configurations:
- Model 11000 – Base hydraulic gun without attachments; ideal for operations with existing hose assemblies.
- Model 11000GB – Adds an integral gauge mounted to the gun body for direct pressure monitoring.
- Model 11020 – Complete assembly including a 26-inch high-pressure hose, integrated pressure gauge, and Giant Button Head Coupler outlet.
Each model features a detachable handle with multiple functions: it measures lubricant volume in one-ounce increments, serves as a push rod to return the barrel piston, and locks or unlocks the barrel cap. This design reduces the need for additional tools during valve maintenance procedures.
Operational Characteristics
- Operating Pressure: Up to 10,000 PSI
- Delivery Rate: 1 oz per 50 strokes
- Capacity: Accepts standard “J” size sticks (9½ oz) or bulk lubricant fill
- Outlet Connection: ¼″ NPT (other sizes available)
The self-priming system minimizes manual priming steps and allows immediate operation after filling. The measured delivery rate helps prevent excess lubricant discharge, reducing the risk of contamination in valves or process streams.
Safety features include a tamper-proof internal relief valve to prevent overpressurization and a safety-latch mechanism that protects against accidental discharge. The heavy-duty metal construction and corrosion-resistant finish ensure reliable service in marine, chemical, and outdoor environments.
The grease guns function reliably in any orientation—upright, inverted, or horizontal—to accommodate the tight access angles common in valve and piping maintenance. Sure Grip surfaces provide secure handling with gloved hands or in wet, oily conditions.
Service and Maintenance
All internal components are field-replaceable without special tools. The manufacturer stocks replacement parts for the 11000 Series to support quick service and minimal downtime. This maintainable design extends equipment life compared to sealed, non-serviceable units.
The ¼″ NPT outlet is standard, with optional sizes available to match specific hose assemblies and valve fittings, allowing seamless integration with existing maintenance systems.
Applications
Primarily used for lubricating ball, gate, and plug valves in natural gas, oil, and chemical service, the 11000 Series also supports hydrostatic testing, wellhead maintenance, and other high-pressure service operations. The equipment’s measured delivery and pressure rating make it suitable for controlled fluid injection during testing and valve maintenance procedures.

FEATURES AND BENEFITS
Pressure and Performance
- 10,000 PSI Operating Pressure – Handles the most demanding valve lubrication requirements in oil and gas operations, where lower-pressure equipment fails to deliver adequate grease penetration.
- Superior Performance with Viscous Materials – Pumps thick lubricants, sealants, packings, and cleaners that would clog standard grease guns, helping ensure proper valve protection in extreme-temperature applications.
- Self-Priming Operation – Minimizes manual priming steps, allowing technicians to begin work immediately after filling.
Safety and Control
- Tamper-Proof Internal Relief Valve – Protects equipment and operators by preventing dangerous overpressurization —a critical safety feature for high-pressure gas systems.
- Safety Latch Mechanism – Prevents accidental discharge during transport or storage, reducing injury risk and material waste.
- Measured Delivery – Detachable handle features one-ounce calibrations, enabling precise lubricant application and preventing excess material discharge that can contaminate gas streams or create safety hazards.
- Double Bypass Valve Stop and Sliding Stop Link – Provides precise control during operation, allowing operators to work confidently in tight spaces around valves and piping.
Design and Usability
- Heavy-Duty Metal Construction – Built to withstand drops, impacts, and harsh handling common in field operations, unlike aluminum or composite alternatives that crack under stress.
- Corrosion-Resistant Surfaces – Maintains performance and appearance despite exposure to saltwater spray, chemical atmospheres, and extreme weather conditions found in offshore platforms and coastal facilities.
- Usable in Any Position – Functions reliably whether held upright, inverted, or horizontally, accommodating the awkward angles often required when accessing valves in confined spaces.
- “Sure Grip” Surfaces – Maintains secure handling with gloved hands or in wet, oily conditions typical of field maintenance work.
- Handle Retaining Strap – Keeps the detachable handle attached to the gun body, preventing loss during transport or storage.
Versatility and Maintenance
- Easy Refilling – Accommodates standard “J” size sticks (9½ oz. capacity) or bulk lubricants, providing flexibility for different maintenance procedures and reducing material costs through bulk purchasing.
- Easily Serviceable – All internal components can be accessed and replaced without specialized tools, minimizing downtime and repair costs.
- Readily Available Replacement Parts – Dualco stocks all components, ensuring you won’t wait weeks for a critical seal or valve to restore equipment to service.
- Multiple Outlet Configurations – Standard ¼” NPT outlet, with other sizes available to match your specific hose assemblies and valve fittings.
