The biggest issue with TPU tubes is in the fragility of valves. This serves as a key weight-saving measure—plastic valves are lighter compared to metal ones, yet they also represent the most vulnerable point of failure. During the inflation process, pumps exert pressure on valve stems, which for some plastic valves may exceed their limits, resulting in valve breakage and air leakage.
Most TPU manufacturers use a sticker at the plastic valve base to stabilize it, but this solution only partly addresses the issue and doesn't fully hold the valve.
As a professional TPU tube manufacturer, ridenowtech has developed a patented holder for plastic valves, addressing the issue of plastic valve damage that can lead to air leaks.
【Only for Presta Valve】These holder are compatible with tpu tube with plastic presta valve, and metal presta valve without threads. , not for schrader valve.
These holders are compatible with Ridenow and all tpu inner tube with plastic valve stems and metal presta valve without threads
It weighs only 0.7 grams
Quantity: 2 Pack, a total of 4 holders (2 holders per pack)
