Haltec Large-Bore to Standard Tyre Valve Adapters 5-Pack — 8807N-4 Solid Brass, OTR/Farm

Haltec 5-pack 8807N-4 adapters convert large-bore OTR and agricultural tire valves to standard bore fittings for routine air service.

These Haltec 8807N-4 valve adapters are solid-brass fittings designed to let mechanics, fleet operators, and farmers use common tire gauges, inflators, and air tools on large-bore truck and off-road tires. Each adapter threads over larger valve stems and reduces the bore to a standard size, making pressure checks and inflation faster without changing valves or specialized tools.

How do these adapters make tire service easier on heavy equipment?

By adapting the large-bore valve down to a standard bore, the adapters let you use conventional gauges and air chucks. That eliminates the need for special fittings and speeds up routine maintenance across mixed fleets.

• Instant compatibility with standard bore gauges and inflators
• Reduces downtime by simplifying valve access
• Fits over .485-26 valve cap thread size common on OTR tires

Are these adapters durable enough for frequent field use?

Yes—each adapter is machined from solid brass for corrosion resistance and mechanical strength in demanding environments. Brass resists rust and holds threads precisely, making the adapters reliable through repeated connect/disconnect cycles.

• Solid-brass construction for longevity in wet or dusty conditions
• Maintains thread integrity under frequent use
• Works well in both shop and outdoor settings

Which valve stems and equipment do the Haltec 8807N-4 adapters work with?

These adapters are sized to fit over large-bore stems with .485-26 valve cap threads and reduce the opening to accept standard-bore tools. They are suitable for OTR truck tires, farm implements, and other heavy equipment that use oversized valve hardware.

• Compatible with large-bore valves on off-road trucks and agricultural tires
• Interfaces with common inflators, pressure gauges, and air hoses
• Sold as a 5-piece set to outfit multiple vehicles or spare kits

How should I install and care for these adapters?

Installation is straightforward: thread the adapter over the existing large-bore valve cap threads until seated, then attach your standard tool. Keep the threads clean and store spares dry to extend service life; occasional inspection for wear is recommended when used heavily.

• Hand-thread onto valve cap threads and snug—no special tools required
• Wipe threads clean before installation to prevent cross-threading
• Store spare adapters in a dry kit or toolbox to avoid contamination

Who is this for: The Haltec 5-pack 8807N-4 adapters are ideal for fleet managers, mechanics, agricultural operators, and off-road maintenance crews who need a simple, durable way to use standard tire service tools on large-bore valves. If you manage multiple vehicles or want spare adapters for field kits, this solid-brass 5-pack gives compatibility and reliability without replacing valve stems or buying specialized gauges.
