SENZEAL 5x Car Tyre Valve Tool Steel Shaft Bike Repair Kit Valve Key Red

You are looking at these valves and the tools because you think your valve core is leaking ? That is exactly what those are meant to be used for. Simply replace the valve core using either tools and stop your tyres from going flat.However, if you are unsure whether the leak is coming from your valve core or valve stem (rubber tubing), spray some soapy water and hopefully you may see the bubbles forming indicating where the leak is. If it's a leaky valve stem you need replacing the stem not the valve core.Having said this, this product is good and does the job it's supposed to do and value for money. 20 valves to keep you going for few years.

As an older woman with an electric bike, I was having trouble putting air in rear tyre, using this great little gadget, I removed the old valve, replaced the new valve and pumped up my tyre, so easy. Great quality product at a very good price.

Ok but core hole could be better if it was deeper and central to the main shaft

So far I've used 3, 2 for my car (slowly loosing pressure) and one for my lawn mower. For the car I'd wanted to put goop in one while because I think the alloy being scuffed might be some of the problem for that wheel. This allowed me to more easily install the Goop and swap out the valve quickly and without any hassle.The accompanying silver tool would be sufficient on it's own, the red handled tool is a welcome addition and nice to have.

Small and compact 2 in 1 valve core remover. My second favourite one.

Handy little tool I keep one in each of my classic cars tool kit

It's what I need

Very useful
