QWORK TR572 Brass Commercial Valve Stems 10-Pack, 3.75" Length, 200psi Heavy-Duty EPDM Seal

QWORK TR572 brass valve stems are heavy-duty replacement stems for tubeless commercial truck and bus tires, sold as a 10-piece pack with 3.75" length and a 200psi cold-pressure rating.

Built to withstand the demands of commercial fleets, these valve stems combine a brass body and EPDM rubber gaskets to resist leaks, ozone exposure, and repeated service intervals. The TR572’s dimensions fit standard tubeless rims used on trucks and buses, and the 200psi cold rating provides a wide safety margin for heavy-duty applications. Supplied in a convenient bulk bag of ten, they streamline maintenance and spares management for shops and fleet operators.

Are these TR572 valve stems compatible with my truck or bus wheels?

These valve stems are designed for tubeless commercial wheels that accept a 16mm (Φ 0.625") rim hole and need an effective stem length of about 95mm (3.75"). They work with most truck and bus rim profiles that use replaceable rubber-stem arrangements. Always verify your rim hole diameter and required stem length before purchase.

• Effective length: 95 mm (3.75")
• Rim hole size: 16 mm (Φ 0.625")
• Designed for tubeless commercial rims
• Check rim specs to confirm fit

How durable and leak-resistant are the QWORK TR572 stems?

The TR572s use a brass body for corrosion resilience and EPDM rubber gaskets to maintain an airtight seal under repeated mounting and tire service. Brass resists galvanic degradation and the EPDM compound prevents common leak paths around the base. Combined, these materials extend service life compared with cheaper alternatives and reduce downtime from slow leaks.

• Solid brass construction for corrosion resistance
• EPDM rubber gaskets to prevent leaks
• Ozone-resistant materials to slow environmental aging
• Suitable for repeated mounting and dismounting

What pressure and environmental conditions can these valve stems handle?

QWORK TR572 stems are rated to hold up to 200psi cold inflation pressure, giving a substantial safety margin for most commercial tire pressures. They are manufactured to resist ozone exposure and routine environmental stressors, which helps maintain sealing integrity across seasons and long service intervals. That makes them a reliable choice for fleet vehicles operating in varied climates.

• Cold pressure capacity: up to 200 psi
• Ozone-resistant design for environmental durability
• Appropriate for heavy-duty commercial use
• Good aging characteristics under normal operating conditions

What comes in the pack and how do I manage replacements?

This product ships as a 10-piece bag of TR572 valve stems, providing enough spares for several tires or routine shop inventory. Buying in a 10-pack reduces downtime by keeping replacements on hand and simplifies purchasing for fleet maintenance. Install with standard valve stem tools and torque practices to ensure proper seating and seal integrity.

• Quantity: 10 valve stems per bag
• Packaging suited for shop inventory or fleet spares
• Compatible with standard valve installation tools
• Recommended to replace stems during tire service intervals

Who is this for: The QWORK TR572 brass valve stems suit fleet managers, commercial tire shops, and truck or bus operators who need dependable, leak-resistant stems in bulk. If you maintain tubeless heavy-vehicle tires that use a 16mm rim hole and require a 3.75" stem with high pressure capacity, this 10-pack provides a practical, durable spare solution. For precise fitment, compare your rim hole diameter and required stem length to the TR572 specifications before ordering.
