MS525AL metal tire valve
Engineered specifically for high-speed alloy wheel applications, the MS525AL Aluminum snap-in tubeless valves reduce unsprung rotational weight while maintaining absolute high-pressure integrity. We machine the main body in-house from premium automotive-grade aluminum on our multi-axis CNC centers, ensuring exact-tolerance thread pitches and a flawless mechanical fit. Backed by severe-temperature EPDM sealing grommets and 100% automated pre-shipment leak testing, the MS525AL delivers mathematically verified, corrosion-resistant airtight performance for Tier-1 automotive assembly requirements.

Fortune metal tire valve: the engineering advantage
We manufacture OE-quality metal tire valves strictly under ISO/TS16949 accreditation, covering everything from high-pressure passenger snap-ins (TR600HP series) to heavy-duty large-bore commercial truck valves (TRJ650 series). By physically controlling the CNC machining and rubber formulation on our own factory floor, we completely eliminate the catastrophic failure points common in low-end aftermarket metal valves.
premium copper & aluminum (zero zinc alloy)
Whether we are engineering a straight TR416 clamp-in valve (strictly machined to a Φ18.5x40 mm external dimension for .625" rim holes) or a heavy-duty TR-618A agricultural valve (maintaining an exact 15.9 mm solid base), we machine the main bodies exclusively from premium copper rods and aerospace-grade aluminum. We strictly prohibit the use of zinc alloy main rods in our facility. Zinc alloy valves suffer from poor material stability, causing them to crack, age, and catastrophically lose sealability under continuous radial stress. Furthermore, we completely reject the aftermarket cost-cutting practice of using lower copper content, reducing critical external dimensions by fractions of a millimeter, or drilling larger bottom holes to save material. By physically maintaining 100% of the engineered metal wall thickness, we mathematically guarantee our valves can sustain extreme operational loads without structural deformation.
in-house CNC threads & precision truck bends
A metal valve relies entirely on mechanical tolerances to prevent air bypass. From the internal core threads of our MS525AL aluminum valves (machined precisely to a Φ17x42 mm external dimension using exact-tolerance HN9 hex nuts for .453" rim holes) to the complex multi-axis bends of our V3.20 metric truck series (such as the exact 27° bend on the Φ16x115 mm V3-20-6), we do not rely on cheap, inaccurate casting. Every metal stem and hex nut is physically cut on our internal CNC processing machines. This hardware-driven control creates mathematically high-precision sizes and smooth mating surfaces, physically eliminating the scratches and surface blemishes that cause inferior valves to leak at the rim hole.
international high-standard EPDM components
The rubber component on a metal valve—whether it is the molded base of a TR600HP locking into a .453" rim hole (strictly rated for a maximum cold inflating pressure of 100 PSI / 720 kPa at room temperature) or the heavy-duty RG60 sealing O-ring on a commercial V3.20 truck valve—is your ultimate air barrier. We formulate our sealing components using international high-standard EPDM rubber. We categorically reject inferior natural rubber, which easily ages in the air and fractures under mechanical stress during automated installation. Combined with our premium 9002# high/low-temperature resistant valve cores, our in-house EPDM formulation guarantees absolute sealability and material stability across extreme temperature bandwidths from -54°C to +150°C.
