GIANT (EM) Valve Thread Calibrator, Tap and Core Tool – 3-in-1
GIANT valve thread calibrator | Internal Ø 7.5 mm, external Ø 11.5 mm | Sold as 1 pc.
Oversized vehicle wheels use valves considerably larger than those on passenger cars, so repairing their thread calls for a tool built to that scale. This calibrator repairs external (Ø 11.5 mm) and internal (Ø 7.5 mm) thread on standard GIANT valves used on industrial vehicles. The same tool also doubles as a GIANT valve core tool, so one piece of kit replaces two separate items on the bench. The knurled handle adds precision, and the whole tool has rust protection that significantly extends its working life.
What it's used for
A sand-clogged, corroded, or slightly damaged GIANT valve thread can make it hard to fit a nut or cap even though the valve itself still works fine. Instead of replacing the whole valve on an oversized vehicle wheel, running the calibrator over the external or internal thread restores its correct shape. The same calibrator also handles a GIANT valve core swap, so one compact tool covers two routine tasks for shops servicing industrial vehicles.

Frequently asked questions
How are GIANT (EM) valves different from standard ones?
GIANT valves have larger thread dimensions and are mainly used on oversized vehicle and industrial machinery wheels, where standard valves aren't suitable.
When is it worth using the calibrator instead of replacing a GIANT valve?
If the valve itself still works and the only issue is a sand-clogged or slightly damaged thread, the calibrator restores its shape without replacing the whole, often costly part.
What thread sizes does this calibrator fit?
Internal thread at 7.5 mm diameter and external thread at 11.5 mm diameter, found on standard GIANT (EM) valves used on oversized vehicle wheels.
Can this tool also swap a valve core?
Yes — the calibrator doubles as a tool for GIANT valve cores used on industrial vehicles.
