1. Produce high quality rubber by ourselves . Some suppliers produce bad rubber whose lifespan is about 1 year, after a year that rubber may get as hard as stone and easy to break down . Our rubber lifespan is 4 years to 6 years , very reliable !!

2. Paint Chemlok, improve tensile . Chemlok is a chemical substance used to bond metal and rubber , without chemlok the rubber can be tear apart from metal very easy . Now our valve tensile is over 680N , rubber and metal bonded very tight .

3. Every valve Leaking Tested . We test every valve before sale to customers , if any valve leak , we promise to compensate a whole bag .

Some suppliers may category their quality by A level , B level or C-level , they may skip one procedure to cut down price and get B level , skip more procedures to cut down prices further and get C level . Our factory do not skip any procedure , we only produce reliable good quality products . My boss have long experience producing tyre vlaves , as much as my boss know about Chinese valve market , our quality is top 10 good quality in Chinese market .
