Milton S-986 Heavy-Duty Straight-Foot Tire Pressure Gauge, Dual-Head Chuck, 10–160 PSI, 13¼" Reach

Milton S-986 is a heavy-duty straight-foot tire pressure gauge with a dual-head chuck that reads 10–160 PSI and is built to reach inner duals and rugged commercial tires.

This service-grade pressure gauge combines a long 13 1/4" body, durable plated brass construction and a four-sided nylon indicator to deliver clear, repeatable readings for trucks, RVs, tractors and passenger vehicles. Designed for mechanics and fleet operators who need a tool that sustains frequent use, it measures in 2 PSI increments and includes metric kilopascal markings for wider compatibility. The dual-head chuck makes accessing tight inner dual tires straightforward, while the solid construction helps resist wear in demanding environments.

How accurate and durable is this Milton pressure gauge?

The S-986 was engineered for consistent readings and long service life. Its seamless drawn brass tube and four-sided nylon indicator reduce wear and keep the scale readable through heavy use, unlike cheap pad-printed dials that fade quickly.

• Precision-seamless brass tube for stable measurement
• Four-sided nylon indicator resists abrasion and maintains visibility
• 2 PSI resolution across the 10–160 PSI range for clear increments

Will this reach inner dual tires and awkward valve positions?

The straight-foot design paired with a dual-head chuck allows easier access to inner dual valves and recessed stems that are hard to reach with standard gauges. The 13 1/4" length gives added reach without sacrificing control when seating the chuck on a valve.

• Dual-head chuck accesses both outer and inner duals without repositioning
• Long 13 1/4" body provides extended reach for recessed valves
• Straight-foot layout keeps the gauge steady during readings

What pressure units and ranges does the gauge display?

The Milton S-986 displays PSI and kPa so it fits North American and metric preferences. Its scale covers most heavy-duty and passenger tire needs, spanning low-pressure applications up to higher commercial tire requirements.

• 10 to 160 PSI range, useful for automotive to heavy-truck tires
• 2 PSI increments for practical on-vehicle adjustments
• 80 to 1100 kPa markings in 20 kPa steps for metric reference

How does the S-986 compare for everyday shop use?

Built for repeated service checks, this gauge balances rugged materials with user-friendly features. It's a straightforward tool that minimizes fuss—no batteries, no electronics—so technicians can quickly verify pressures during inspections or before road service.

• Robust metal construction stands up to shop and field environments
• Simple mechanical operation reduces maintenance and downtime
• Clear, tactile indicator speeds reading under low-light conditions

Who is this for: The Milton S-986 is aimed at fleet managers, truck and RV owners, service technicians and anyone who regularly checks tires on heavy or dual-wheel vehicles. If you need a dependable, long-reach mechanical gauge that reads both PSI and kPa and works well with inner duals, this gauge is a practical shop-ready choice.
