Mellbree 2-Pack Tire Valve Extension, 90 Degree Schrader Tire Valve Stem Extension Brass Adaptor Compatible for Passenger Cars, Stroller, Bicycles, Motorcycles, Trailers, RV and Recreational Vehicles

Nice quality, excellent price, fast delivery!

Works great.

These came on time and look good. unfortunately i need 137 degrees minimum to cleat my wheel covers. I bent them to 137 and didn't notice the cracks until i installed them. The both leaked. I couldn't use heat because of the rubber seals. Disclaimer: I have been a metal worker / machinist for over 40 years. Failure was my fault for thinking i could get 2 more degrees from them. Tubing is to thin and brittle to do that without heat.

What a great item for the smaller bikes and even larger bikes! Easier to fill the air!

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.

Could be user error but I struggle to use this as a temporary extension to fill up my e-scooter tire. The tire valve isn’t quite long enough on its own for my compressor so I ordered this to help pump it up. When I install or remove this extension, the valve stem lets out air while it’s being screwed on or off, so kinda negates any additional psi I’ve added to the tire. Could be a technique to it but I haven’t figured out a way to do so reliably.

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.

Very pure quality

Installed on dual wheel motorhome with dress rims. Work well. Appear to be well made.

Son muy buenos y fáciles de instalar

Poor quality had to return, not worth the price.

Bcp moins cher qu'en magasin, bonne qualité, m'a permis de déporter une vise de purge de boîtier thermostat sur un moteur normalement inaccessible.

Me funcionaron muy bien para inflar la llantas de mi moto, ahora puedo pasar a cualquier gasolinera sin problema
