The Haltec WH-546 Large Bore Swivel Valve (MPN: WH-54-6 / HAWH546) is a premium-grade, heavy-duty tire valve designed for large off-the-road (OTR), industrial, and commercial vehicles. Engineered with a 90-degree single bend, this valve utilizes a swivel design that allows for easy alignment and access during inflation and pressure checks, even in tight or complex wheel configurations.
Built by Haltec Corporation—the industry leader in tire inflation systems—this valve features a durable brass construction that ensures maximum corrosion resistance and a leak-free seal under extreme operating conditions.

• Swivel Design: The innovative swivel base permits independent rotation, allowing you to position the valve at the perfect angle for convenient servicing without loosening the rim seal.
