Dueilgo Tractor Valve Stems TR618A 10-Pack — Brass & EPDM, 2.12" Length, 200 PSI

Dueilgo TR618A valve stems are durable brass-and-EPDM replacements engineered for tubeless agricultural and industrial wheels, sold in a 10-piece set.

These TR618A valve stems are designed to restore and maintain reliable air retention on tractors, graders, backhoes and other heavy equipment that use standard 5/8" valve holes. Built from brass with EPDM rubber components, they resist corrosion, high temperatures and wear—making them a practical maintenance item for fleets and farm machinery. Each stem measures 2.12" long, meets a maximum air pressure rating of 200 PSI, and is supplied as OE-compatible replacement hardware for common agricultural valve bores.

How do these valve stems improve tire maintenance?

Replacing worn or cracked valve stems prevents slow leaks and reduces downtime spent reinflating tires. The TR618A combines a metal body for mechanical strength with EPDM seals to keep air tight under heavy-duty conditions.

• Prevents air loss from degraded rubber stems or damaged cores.
• Brass body resists rust and mechanical damage from rim edges.
• EPDM withstands temperature extremes up to 212°F (100°C).
• Easy swap-in for standard 0.625" valve holes on industrial rims.

Are these valve stems compatible with my tractor or heavy equipment?

The TR618A is made for tubeless agricultural and industrial wheels that accept a 5/8" (0.625") stem hole. They are commonly used on tractors, graders, backhoes and excavators when a metal valve stem is required for reliability under load.

• Fits valve bore: 0.625" (5/8").
• Length: 2.12" to suit standard rim depths.
• Designed for tubeless tire assemblies on heavy equipment.
• Sold as a pack of 10 for fleet or multiple-tire servicing.

What are the materials and pressure limits of TR618A stems?

These stems combine a brass outer body with EPDM rubber sealing components to balance durability and airtight performance. They are rated for a maximum air pressure of 200 PSI and built to withstand the heat and abrasion found in agricultural environments.

• Brass body for corrosion resistance and strength.
• EPDM rubber seals tolerate high temperatures and ozone exposure.
• Maximum rated pressure: 200 PSI for typical heavy-duty use.
• OE reference number: TR618A for easier replacement ordering.

How should I inspect and replace valve stems?

Regular inspection helps catch cracks, leaks or seal deterioration before they cause flat tires or unsafe low-pressure conditions. Replace stems that show visible wear, leaking on inflation, or that are more than a few seasons old—especially on equipment exposed to abrasive conditions.

• Check for cracking, hardening, or exposed corrosion at every tire service.
• Use proper valve-core tools and torque when installing to avoid damage.
• Keep a pack of TR618A stems on hand for quick field repairs.
• Dispose of worn stems; do not attempt temporary patches on metal stems.

Who is this for: Maintenance crews, farmers, rental shops and equipment owners who need reliable tubeless valve stems for heavy-duty wheels will find the Dueilgo TR618A a practical, cost-effective choice. The 10-piece pack suits multi-tire servicing and fleet upkeep, offering a straightforward replacement that reduces air-loss incidents and supports safe, consistent tire pressure management for agricultural and construction machinery.
