QWORK 4Pcs Tyre Valve Stem, 90 Degree Angled Bolt-in Valve Stems for Car Motorcycle Tyre,Anti-Leakage

no leak, easy install

Looks like good quality. Unfortunately, they didn't fit my 2003 Yamaha so I returned them.

I bought these because I changed my motorcycle tires. These will make it easier to air up. Very easy to install.

Works as should

These are junk, Over time the bottom grommet rots out causing air to leak. When tightening them you cannot snug them down due to fear of crushing the rubber gasket. Went out one morning and found my bike with a flat tire. Save your money and purchase the rubber 90 Degree valve stems

I had two of the four of these stems with a leaky core and when trying to remove the core to replace they were stuck when fully threaded out. Must have been a manufacturing defect internally. I had to pull them out with pliers. tried new cores and those leaked and got stuck as well and were ruined when pulled out. Two of them work just fine, luckily I only needed two.

Permiten alcanzar la valvula con facilidad dando acceso a cualquier elemento para inflar. Tienen buen sello y son de un material robusto.

Leaky 👎
