To understand how this specialized part functions, its unique design can be deconstructed through its manufacturing and component segments:

1. WH (Wheel Hub / Swivel Designation): Identifies Haltec's heavy-duty industrial series components built to attach securely to heavy equipment wheels. [1]
2. 330 (Chamber & Base Profile): Specifies the standard base diameter and thread configuration required to match industrial large-bore spud structures. [1, 2]
3. J-693 (Tire & Rim Association Standard): The official TR J-693 industry specification designating the precise dual-bend shape required for planetary gear wheel drives.

Key Features & Benefits

• Planetary Gear Clearance: Features a double 60° bend routing (60° bend #1, a 1-inch offset, and a 60° bend #2) specifically engineered to navigate around protruding planetary wheel hubs.
• High-Flow Efficiency: Standardized as a "Large Bore" valve profile to significantly accelerate inflation and deflation times on massive earthmoving tires. [1, 2]
• Complete Ready-to-Install Assembly: Shipped fully equipped with all critical installation components, including the valve core, hex cap, spud nut, and sealing rubber grommet.
• Maximum Durability: Precision machined from heavy-duty brass to remain corrosion resistant, leakproof, and stable under extreme mechanical vibrations and severe climate conditions.
