Frequently Asked Questions

Nitto refers to the plug/socket style — fast-connect and standard across Aussie tools. BSP is the thread type (British Standard Pipe), used for tight, leak-proof connections.

Yes, but be consistent where possible. Brass is corrosion-resistant and good for workshop air, while steel is tougher and preferred in harsher conditions.

Absolutely. We carry inline oilers to extend air tool life and regulators to control PSI at the tool — a must for long-term reliability.
