Air Tool Oil

About Air Tool Oil

Air tool oil is a specialised lubricant formulated specifically for pneumatic tools and compressed air equipment. Unlike general-purpose oils, it features a precise viscosity that allows it to atomise effectively in air streams whilst providing superior protection against moisture, rust and internal component wear. MyToolShed.co.uk stocks professional-grade air tool oil from trusted brands like Sealey, available in individual bottles or convenient multi-packs for busy workshops.

Regular lubrication with quality air tool oil is essential for maintaining the performance and longevity of pneumatic equipment including impact wrenches, nail guns, air hammers and spray guns. Just a few drops applied through the air inlet before and after use significantly reduces friction, prevents premature wear of moving parts, and protects against corrosion caused by moisture in compressed air lines—a particular concern in the UK's damp climate.

Applications

Air tool oil is used across numerous trades and industries where pneumatic equipment is essential:

• Vehicle mechanics and auto technicians – maintaining impact wrenches, air ratchets and pneumatic hammers for daily repair work
• Body shop professionals – ensuring spray guns and air sanders perform consistently for quality paint finishing
• Joiners and carpenters – keeping nail guns, staplers and pin nailers operating reliably on construction and joinery projects
• Manufacturing facilities – implementing scheduled lubrication programmes for extensive pneumatic tool fleets
• Construction workers – maintaining demolition hammers, cut-off tools and fastening equipment on-site
• Plant maintenance engineers – servicing industrial pneumatic systems across various sectors
• DIY enthusiasts – properly maintaining home workshop compressor-powered tool collections

Choosing The Right Air Tool Oil

Viscosity grade: Most pneumatic applications in UK workshops are well-suited to ISO 32 grade oils, which flow freely through air systems without causing drag. Heavier ISO 68 grades may be appropriate for demanding industrial applications or colder environments.

Anti-corrosion properties: Select oils with robust rust inhibitors to combat moisture naturally present in compressed air lines, particularly important given Britain's humid climate and the condensation that forms in compressor tanks.

Pack size: Individual bottles suit occasional users and small workshops, whilst multi-packs like Sealey's 12-bottle format offer better value for professional environments with multiple pneumatic tools requiring regular maintenance.

Application method: Consider whether you need bottles with applicator spouts for direct tool lubrication or oil suitable for automatic in-line lubricators that provide consistent lubrication across your entire air system.

Brand reliability: MyToolShed.co.uk stocks established manufacturers like Sealey, whose formulations have proven track records in demanding professional environments across automotive, construction and industrial sectors.

Safety Information

Always disconnect the air supply before applying oil to prevent accidental tool activation. Wear safety glasses during application as residual air pressure may cause oil to spray. Store containers in cool, dry conditions away from heat sources and direct sunlight. Whilst air tool oil has low toxicity, avoid prolonged skin contact and wash hands thoroughly after handling. Ensure adequate workshop ventilation during use as oil mist may be expelled from tool exhausts. Dispose of used oil responsibly in accordance with local authority environmental regulations.

Frequently Asked Questions

How often should I lubricate my pneumatic tools?

Add 3-4 drops of air tool oil through the air inlet before each use and after extended operation periods. For tools used continuously throughout the day, lubricate at the start of each shift and mid-shift. If you've fitted an in-line lubricator to your air system, daily manual oiling may be unnecessary, though periodic verification is recommended.

Can I substitute motor oil for air tool oil?

No, motor oil is unsuitable for pneumatic equipment. Air tool oil has specific viscosity characteristics allowing it to atomise properly in compressed air without leaving gummy deposits. Motor oil is too thick, contains detergents that create harmful residues, and lacks the moisture-displacement properties essential for protecting pneumatic components from corrosion.

Why is my air tool still underperforming after lubrication?

If oiling doesn't restore performance, check your compressor is delivering adequate pressure (typically 90 PSI for most tools), inspect air filters for blockages, and examine your air lines for moisture accumulation. MyToolShed.co.uk also stocks filter regulators and moisture traps that can resolve these common compressed air system issues.
