Air King Universal Swivel

The Guardair Air King Universal Swivel is a 3/4 inch male air gun coupler built to connect an air hose to an air tool. It is designed for technicians and operators who need a reliable, leak-free junction in pneumatic systems. The aluminum construction provides corrosion resistance while keeping the assembly lightweight for handheld use.

3 5/16 in overall length

The coupler measures 3 5/16 inches in overall length, giving enough reach for tight fittings without adding bulk. Its compact profile fits between the hose and tool without forcing awkward angles. The swivel action reduces hose twist during operation, though the fixed length offers no extension beyond the stated dimension.

Includes safety pin

A safety pin is included to lock the connection and prevent accidental disconnection under pressure. This feature addresses the primary failure point in quick-disconnect setups where vibration or snagging can unseat the coupler. Buyers who need a locking mechanism for high-vibration environments will find this essential; those using low-pressure static lines may not require it.

Questions about this item

Will the 3 5/16 in overall length clear my existing hose reel swivel?

The coupler measures 3 5/16 in end to end, so compare that dimension with the clearance on your current reel swivel before installing.

How do I confirm the safety pin is engaged after connecting the hose?

After pushing the hose onto the male fitting, the safety pin should sit flush in its groove and resist light tugging on the hose.

Does the box contain thread sealant or additional fittings for my 3/4 in line?

The package includes the aluminum Air King coupler with its safety pin only; thread sealant and any extra adapters must be purchased separately.
