6-Pack Valve Stem Extenders, Mellbree 45 Degree 90 Degree 135 Degree Schrader Tire Valve Extension Compatible for Dual Wheels Passenger Cars, RV, Stroller, Bicycles, Motorcycles and Trailers

These valve stem extenders work as advertised. I used the 90° pieces on my dual rear wheels and it made checking/adding air so much easier. Threads were clean, no leaks after a quick snug with a wrench and a dab of thread sealant on the Schrader side. Stainless finish looks solid. Nice that the pack includes multiple angles (45°, 90°, 135°) so you can mix and match. Good value.

Good product; it makes pumping air into my motorcycle tires much easier.

Does the job , the quality and finish are slightly lacking but overall worked for me for what I intended to do with it. Pretty easy to install. Airflow seems normal. Fit is good.

I bought these to make checking/adding air to my Harley tires possible. The factory air stem is almost impossible to access with my tire gauge and air pump, and the tires would often lose significant air just trying to check pressures because of the awkward angle. (Harley has FINALLY modified their wheel rims to face the valve outward on newer bikes!) With a 135-degree extension on both front and rear wheels, I can now easily measure the pressure and add air with a leak-free connection.

on time, as advertised,

I thought these would be helpful to check the tire pressures and inflate if needed. However they leaked air due to the fact they loosened up while driving my Class A Motorhome down Vail Pass. Both outside dually tires deflated and before I realized it my Motorhome was swerving so bad I almost lost control. I removed them and threw them in the trash. I purchased one piece brass stems and had a truck tire shop install them.

The price was fair enough I did however have to purchase a valve stem wrench as all the valves were loose causing air to leak out through them. Once the valves within the extenders were tightened it was easy to inflate the tires to their required pressure. As I needed it right away the wrench had to be purchased at an auto parts store and it was almost half the price of the valve stem extenders. Perhaps this was an isolated problem.

Beautiful and quality!
