TR-650-03 Truck & Bus Screw-On Repair Valves

Engineered for the Θ=65° clamp-in profile with a 15.9mm rim bore specification, the TR-621A truck and bus screw-on repair valves pair an A=39 base with a B=55.5 bend length on Fortune’s commercial valve line. Built on Fortune’s in-house CNC machining, TR-621A produces bend and thread tolerances consistent with Fortune’s CNC-machined family standard. Qualified for buyers consolidating inventory under one supplier with the TR-618A SKU, TR-621A maintains the 15.9mm rim hole standard across both SKUs.

Fortune metal tire valve: the engineering advantage

The TR-65x series’ ten-SKU multi-β coverage rests on three engineering pillars. First, Fortune’s in-house CNC machining delivers the bend and thread tolerances that eliminate casting variability at incoming inspection. Second, the multi-β spread (60°/74°/80°/86°/90°) opens five clamp-in segments within Fortune’s bend-angle range, with each SKU anchored to its own A / B dimension pair. Third, the A=27 base dominates seven of the ten SKUs (TR-650 / -652 / -653 / -654 / -655 / -657 / -658), with A=32 / 48 / 64 variants (TR-651 / -659 / -656) extending the family for non-A=27 reach positions.

Zero-Casting Tolerance Standard

Fortune's in-house CNC machining produces all ten TR-65x SKUs' bend and thread tolerances from a single setup, eliminating the casting variability buyers screen for at incoming inspection. The ten SKUs share one machined-fit standard across the family.

Multi-β Bend Spread

The TR-65x series spans β=60° (TR-654) / 74° (TR-655) / 80° (TR-650 / -653 / -657 / -658) / 86° (TR-652) / 90° (TR-651 / -656 / -659), opening five distinct clamp-in segments within Fortune's bend-angle range.

Multi-A Variant Architecture

Seven of ten TR-65x SKUs inherit the A=27 base dimension, while TR-651 (A=32) / TR-659 (A=48) / TR-656 (A=64) extend the family with non-A=27 reach positions. This A=27-dominant architecture gives buyers one common base plus three reach variants.

Fortune metal tire valve applications

Our metal tire valves deliver absolute structural integrity and guaranteed air retention for the most demanding industrial, commercial, and high-performance applications. Engineered specifically to withstand extreme tire pressures, high-speed centrifugal forces, and severe operational temperatures, these valves provide guaranteed OE-level fitment and long-term durability. We manufacture precise sealing solutions that integrate directly into heavy-duty operations across three core vehicle sectors.

commercial fleets & heavy-duty trucks

Designed specifically for continuous radial stress in long-haul logistics. Our heavy-duty commercial metal tire valves (including the V3.20 and TR500 series) are CNC-machined to precisely fit standard 9.7 mm (0.390") and 15.7 mm (0.625") heavy-duty truck rim holes. Engineered for a strict installation torque of 10 to 14 Nm (88-124 in-lbs), they are manufactured to sustain extreme maximum cold inflation pressures up to 200 PSI (1380 kPa). The solid brass construction, combined with severe-environment EPDM O-rings rated for continuous heat exposure up to 130°C (266°F), maintains a perfect airtight seal against the extreme heat radiated from commercial brake drums, ensuring zero air loss on standard heavy-duty steel and aluminum truck wheels.

high-performance passenger vehicles

Engineered for high-speed dynamic stability at speeds exceeding 240 km/h (150 mph). Our passenger metal tire valves utilize a strictly toleranced mechanical clamp-in structure, CNC-machined to an exact ±0.01 mm precision. Featuring heavy-duty hex nuts designed for a strict installation torque of 4 to 6 Nm (35-55 in-lbs), they securely lock into standard 11.3 mm (0.453") valve holes on high-performance aluminum alloy wheels. This construction maintains absolute physical rigidity against extreme highway centrifugal forces, mathematically guaranteeing air retention at maximum cold inflation pressures up to 100 PSI. Coated with an advanced anti-corrosion finish verified by 96 hours of Neutral Salt Spray (NSS) testing, they deliver precise fitment and guaranteed high-speed safety for Tier-1 automotive assembly lines.

agricultural & off-the-road (OTR) machinery

Built for massive payload compressions and severe terrain impacts. Our large-bore agricultural and OTR metal tire valves (such as the TR-618A series) feature heavily reinforced solid metal walls engineered to fit standard 15.7 mm (0.625") rim holes. Equipped with specialized fast-flow core housings (such as the CH-3), they deliver up to 300% higher air-flow rates than standard valves to facilitate rapid liquid ballast filling and high-volume inflation. Utilizing advanced EPDM compounds rated for extreme temperature fluctuations from -40°C to +120°C (-40°F to +248°F), they provide maximum physical resistance against mud and direct mechanical impacts. This mathematically guarantees constant tire pressure under extreme payloads and sustained inflation limits up to 150 PSI in mining, construction, and heavy agricultural environments.
