Description of π² Milton 493-50 1 1/4" Tubeless Tire Valve - High Pressure (Box of 50)
These 1 1/4" high pressure tubeless tire valves offer a maximum air pressure of 80 PSI cold inflation pressure. The TR 600 tubeless tire valves fit a rim hole diameter of .453". 1 1/4" total effective length. Tire and rim type TR 600. Fits rim hole diameter of .453.
As my tests showed, this valve quickly began leaking air from my tire. Despite several attempts to tighten and adjust it, the leak persisted. The only positive aspect is that it was relatively easy to install. However, the constant air leakage renders it ineffective and a waste of money.
Pros
Durable and long-lasting design.
Cons
May require specialized installation tools to properly install.
I bought these tire nipples because I thought they were good quality and made in the USA like all the other Milton branded items I've bought, but they are made in China and are pretty much useless. They don't have enough retaining lugs on the outside of the rim bore to prevent them from being pushed back into the wheel when inflating a tire with a pressure gauge or air chuck. Don't buy them because you won't be happy with them.
Pros
These 1 1/4" high pressure tubeless nipples provide a maximum air pressure of 80psi when cold inflation. Valves for TR 600 tubeless tires fit .453" rim holes.
