Dispensing Guns

About Dispensing Guns

Dispensing guns are precision fluid transfer tools designed to safely and efficiently dispense oils, diesel, petrol and other liquids in workshop, agricultural and industrial environments. These essential devices enable controlled delivery of fluids whilst minimising spillage and waste, making them indispensable for mechanics, farmers, plant operators and DIY enthusiasts across the UK. MyToolShed.co.uk stocks a comprehensive range of dispensing guns from Sealey, including manual nozzles for precise control, automatic fuel dispensers with shut-off mechanisms, and complete gravity-fed dispensing kits for workshop oil changes.

Available configurations include hose-end oil guns for attachment to drum pumps, robust trigger-operated dispensing guns for controlled flow, and brass fluid transfer pumps for chemical resistance and durability. Whether you're performing routine vehicle maintenance, refuelling machinery in the field, or managing hydraulic fluids in industrial settings, the right dispensing gun ensures clean, efficient operation every time.

Applications

Dispensing guns are relied upon daily by professionals and trades across numerous sectors:

• Motor mechanics and vehicle technicians – oil changes, fluid top-ups and routine servicing in garages and MOT centres
• Agricultural contractors and farmers – refuelling tractors, combines and machinery directly in the field
• Plant operators and construction workers – maintaining hydraulic equipment, generators and site machinery
• HGV mechanics and fleet maintenance teams – servicing commercial vehicles and transport fleets
• Marine engineers – dispensing oils and fuels for boat engines and marine equipment
• Industrial maintenance fitters – managing hydraulic systems and machinery lubrication in manufacturing facilities
• Groundskeepers and landscapers – refuelling mowers, strimmers and petrol-powered garden equipment
• DIY enthusiasts – home vehicle maintenance and workshop fluid management

Choosing The Right Dispensing Guns

Fluid Compatibility: Ensure the dispensing gun is suitable for your specific fluid type. Different materials are required for petrol, diesel, oils and chemicals. Brass construction offers excellent chemical resistance for professional applications.

Manual vs Automatic Operation: Manual nozzles provide precise control for measured dispensing and are ideal for workshop oil changes. Automatic nozzles feature shut-off mechanisms that prevent overflow, perfect for unattended vehicle refuelling where hands-free operation is beneficial.

Dispensing Method: Gravity-fed kits are simple and reliable for workshop use, requiring the source container to be elevated. Trigger-operated hose-end guns work with drum pumps for versatile fluid transfer from bulk containers at any height.

Flow Rate and Control: Consider the volume you typically dispense. High-flow applications like vehicle refuelling benefit from larger bore nozzles, whilst precision topping-up requires fine flow control. Look for adjustable flow control valves if versatility is required.

Ergonomics: For frequent use, choose guns with comfortable grips, swivel inlets to prevent hose twisting, and smooth trigger action to reduce hand fatigue during extended dispensing sessions.

Safety Information

Fire Prevention: Always use dispensing guns in well-ventilated areas away from ignition sources, naked flames and sparks. Keep appropriate fire extinguishers accessible when dispensing flammable liquids.

Personal Protection: Wear chemical-resistant gloves, safety glasses and protective clothing when handling fuels, oils and chemicals. Ensure adequate ventilation when working with volatile fluids in enclosed spaces.

Spill Management: Use drip trays to contain spills and have absorbent materials readily available. Dispose of contaminated materials according to UK environmental regulations and COSHH requirements.

Equipment Maintenance: Regularly inspect dispensing guns, hoses and connections for wear or leaks. Replace worn seals promptly and test automatic shut-off mechanisms periodically to ensure proper function.

Frequently Asked Questions

Can I use the same dispensing gun for different types of fluids?
It's best to dedicate dispensing guns to specific fluid types to prevent cross-contamination. Petrol and diesel guns should be kept separate, and oils should not be mixed with fuels. If you must use one gun for multiple fluids, ensure thorough cleaning between different substances and verify material compatibility.

What's the difference between manual and automatic dispensing nozzles?
Manual nozzles require holding the trigger throughout dispensing, providing precise control over flow and exact quantities. Automatic nozzles feature a shut-off mechanism that stops flow when containers are full, allowing hands-free operation ideal for vehicle refuelling applications.

How do gravity-fed dispensing systems work?
Gravity-fed systems rely on elevation rather than pumping action to transfer fluid. The source container is positioned above the dispensing point, and gravity provides the flow pressure. They're simple, reliable and widely used in professional workshops for oil changes, requiring no mechanical pumping mechanism or 240v power supply.
