WAYASDCU TR574 5in Truck Valve Stems 20-Piece Kit — 0.625in Bore, Brass/Copper Tubeless

These WAYASDCU TR574 straight truck valve stems are a 20-piece replacement kit of 5-inch copper/brass tubeless valve stems engineered to fit 0.625-inch valve bores and restore reliable air sealing on truck wheels.

If you maintain heavy-duty vehicles, trailers, or commercial truck fleets, swapping worn valve stems is a simple, high-impact repair that prevents leaks and protects tires. This kit contains 20 OEM-matching TR574 valve stems made from solid brass/copper for corrosion resistance, a long-stem design for easy accessibility, and a 19mm base to match tubeless wheel holes. Each stem is tested for durability so you can replace multiple wheels at once with consistent fit and performance.

How do these valve stems match OE TR574 specifications?

WAYASDCU designed these stems using the original TR574 dimensions so they sit and seal like factory parts. The 19mm base and overall length mimic OE geometry to ensure a snug installation without requiring wheel modifications.

• OE number compatibility: TR574 profile and measurements
• 19mm base diameter for tubeless wheels
• Long 5-inch stem for easier access from hub-mounted wheels
• Fits standard 0.625-inch valve bores in commercial wheels

What materials and testing back up their durability?

These valve stems are manufactured from solid brass/copper alloys that resist corrosion and maintain sealing surfaces over time. WAYASDCU performs strict component testing—pressure checks and material inspections—to reduce failures and extend service life compared with cheap, untested alternatives.

• Solid brass/copper construction for rust resistance
• Pressure-tested to detect leaks before packaging
• Robust base and core to withstand tire pressures of truck applications
• Designed to avoid tire or rim damage during installation

Will these fit my truck wheels and are they easy to install?

The stems are intended for tubeless truck tires with a 0.625-inch valve hole; measure your wheel’s valve bore first to confirm compatibility. Installation is straightforward—no specialty tools are required for most standard installations—and the long stem simplifies inflating and reading pressures on wheels with deep rims or hub covers.

• Inner bore compatibility: 0.625 inches—measure before purchasing
• Tool-free or basic hand tool installation for most wheels
• Long 5in length provides better reach for inflators and caps
• Supplied as a 20-piece kit for fleet or multi-wheel replacements

How does this kit help with fleet maintenance and uptime?

Replacing multiple valve stems proactively reduces roadside failures and slow leaks that lead to downtime and uneven tire wear. The 20-pack format is sized for small fleets or multi-axle installs, letting technicians standardize parts stock and speed up wheel service intervals.

• Bulk 20-piece pack reduces ordering frequency for fleets
• Consistent OE-fit parts simplify technician training and repairs
• Durable alloys cut repeat replacements and emergency calls
• Saves time during multi-wheel servicing and preventive maintenance

Who is this for: vehicle owners, fleet managers, and repair shops that need reliable, OE-matching tubeless valve stems in bulk. If you run heavy trucks, trailers, or commercial vehicles with a 0.625-inch valve bore and want corrosion-resistant, long-stem brass valve stems that are easy to fit and pressure-tested, this WAYASDCU 20-piece TR574 kit is designed to streamline replacements and keep wheels sealed and road-ready.
