Dual Valve Core Tool Standard/Giant
Tool for standard and giant (EM) valve cores | 135 mm length | Sold as 1 pc.
Any given shop deals with both standard valve cores and the larger giant (EM) cores used on truck and machinery wheels. This tool handles both, so there's no need to keep two separate tools on the bench. The profiled plastic handle gives a solid grip, and the metal tip is corrosion-protected to hold up against daily contact with moisture and grease. At just 135 mm long, the whole tool fits in a coverall pocket and is easy to maneuver even in tight spots.
What it's used for
Replacing or tightening a valve core is one of those jobs that comes up dozens of times a day in a tire shop, so both convenience and versatility matter. This tool handles standard valve cores, including the 17-490c and 17-850 models sold in our shop, and also lets you screw in and remove the larger giant (EM) cores. The shape of the metal tip makes working with both core types comfortable, without swapping tools mid-shift.

Frequently asked questions
What's the difference between standard and giant (EM) valve cores?
Giant (EM) cores are larger than standard ones and are mainly used on machinery and heavy truck wheels. This tool handles both types with a single tool.
Which valve cores does this tool work with?
Standard valve cores, including the 17-490c and 17-850 models sold in our shop, as well as giant (EM) cores.
Why a plastic handle instead of metal?
The profiled plastic gives a more secure grip than bare metal and holds up to normal mechanical wear during daily use.
Does this tool work well in tight spots?
Yes — the overall length of 135 mm and the tool's compact size make it easier to work in places where a longer tool would be hard to angle correctly.
