Review on 🏍️ High-Quality OTAUPRS Motorcycle CNC Alloy Tubeless Tire Valve Stems | 90 Degree Design Fits 8.3mm Rim Holes | Sleek Black Finish by Dan Deng

This is complete crap, I ordered them for my bike. The quality of the metal is so poor that at the slightest pressure on the nut, the thread flies off. The o-rings are recessed to allow them to sit flush with the metal, which is great, except one of them had a different o-ring that was too small anyway. The valve core in one of them wasn't even screwed in properly and could be leaking because the little red gasket on it was crushed and torn. Tried both on my rim, both failed, don't buy.
