TR571 Tubeless Metal Clamp-In Valves
The Fortune TR571 is one of the tubeless metal clamp-in valves designed for commercial tire applications, featuring a 90 mm effective reach and a Φ19 mm diameter under the V3.21.5 ETRTO reference designation. Built on Fortune’s HN13 nut platform, it uses a standardized 9002# valve core and an RG15 grommet / RW8 washer combination. This configuration supports consistent component compatibility across Fortune’s V3.21.x valve range, helping distributors streamline inventory management and commercial tire service operations. The TR571 provides a 90 mm reach option for buyers consolidating commercial valve inventory under the HN13 platform and 9002# core standard.

Fortune metal tire valve: the engineering advantage
TR571’s V3.21.5 reference rests on three engineering pillars. First, TR571’s Φ19×90 geometry provides the V3.21.x family’s 90mm-reach reference, with Fortune’s in-house CNC machining producing both diameter and length tolerances from a single setup. Second, TR571’s V3.21.5 ETRTO designation traces to HN13 nut platform and 9002# core standardization, supporting engineering specifications under ETRTO traceability. Third, TR571 operates under Fortune’s VC2 / VC3 dual-cap option platform, allowing buyers to select cap configuration within one V3.21.5 ordering reference.
HN13 Nut + 9002# Core Reference
TR571's V3.21.5 ETRTO designation traces to HN13 nut platform and 9002# core standardization, providing the V3.21.x family's nut-core reference standard. This HN13 + 9002# pairing supports engineering traceability under ETRTO V3.21.5 reference compliance.
V3.21.5 ETRTO Standard Reference
The V3.21.5 ETRTO designation provides a published industry-standard reference for supplier qualification documentation. This explicit standard citation supports audit trails and engineering specifications when 90mm reach procurement is required.
VC2/VC3 Dual-Cap Option Platform
TR571 operates under Fortune's VC2/VC3 dual-cap option platform, allowing buyers to select between two cap configurations within one V3.21.5 ordering reference. This dual-cap option consolidates TR571's cap sourcing without managing multiple V3.21.5 SKU variants.

Why Partner with Fortune for Metal Tire Valves
Backed by 30 years of dedicated manufacturing expertise (Est. 1996), Fortune operates as an ISO/TS 16949:2018 and TÜV SÜD certified direct manufacturer. We do not simply assemble sourced components; we engineer our entire range of metal tire valves—from high-pressure passenger series to heavy-duty commercial truck metal tire valves—from the ground up. By centralizing a 30+ engineer R&D team, 100% in-house CNC processing, and premium copper/EPDM formulations within our facility, we physically eliminate the high-pressure leakage risks common in low-end aftermarket alternatives. We deliver a verified, fact-driven B2B supply chain built for high-volume global execution.
dedicated metal tire valve engineering & CNC innovation
All metal tire valve product development and structural design operations are executed directly by our professional team of over thirty experienced engineers and technicians. Guided by our core principle to “develop with technology,” this team continuously scales our high-pressure metal tire valve production capacity—yielding up to 5 Million units monthly. By integrating over 100+ advanced automated CNC processing machines directly into our assembly lines, we mathematically guarantee a strict machining tolerance of ±0.01 mm for every valve thread and hex nut, ensuring absolute precision and airtight fitment.
ISO/TS 16949 certified metal tire valve production
Our entire metal tire valve manufacturing facility is governed by strict ISO/TS 16949:2018 and TÜV SÜD quality management systems. We do not rely on random batch sampling; 100% of our metal tire valves undergo severe physical testing, including automated high-pressure air leak tests up to 130 PSI / 900 kPa and Neutral Salt Spray (NSS) corrosion testing for up to 72 – 96 hours to guarantee OE-level durability. For high-volume B2B orders, manual counting is obsolete. Our packaging lines utilize advanced automated precision weighing systems accurate to ±0.1 grams, mathematically guaranteeing absolute counting accuracy (exactly 100 pcs/box) before any container is shipped.
high-volume manufacturing & port logistics
Operating out of a highly advanced 25,000-square-meter manufacturing facility located just 45 kilometers from Ningbo Port—the most vital port city in China’s Yangtze Delta—we possess the robust logistical infrastructure required to execute rapid, high-volume metal tire valve exports. This strategic proximity allows us to cut domestic inland transit to under 2 hours, ensuring strict and stable delivery lead times of 15 to 25 days for bulk full container load (FCL) orders directly from the factory floor to your designated global facility.
global OEM servicing & localized support
Our engineered metal tire valves are fully integrated into the supply chains of over 300 OEMs and Tier-1 aftermarket customers across 65 countries in the Americas, Europe, Japan, Asia, and Oceania. To bypass cross-border communication delays and provide superior, localized support for our partners, we strategically established direct warehouses and corporate offices in North America in 2014. By maintaining a constant local inventory of over 2 million metal tire valves, we guarantee direct 24 to 48-hour local dispatch for our North American partners, delivering factory-direct pricing with zero international shipping delays.
