Schrader Universal Tire Pressure Gauge Value Guide

The Schrader Universal Tire Pressure Gauge is a quintessential piece of early automotive history, representing the transition to pneumatic tires. Patented by George Schrader, these cylindrical brass tools were essential for maintaining the very valve stems his family company pioneered.

What affects the value of Schrader Universal Tire Pressure Gauge?

• Condition of the brass finish, as heavy oxidation or deep scratches can lower the $15-$25 market value.
• Legibility of the stamped patent dates and pressure increments on the pop-up scale.
• Functional integrity of the internal spring mechanism and leather seals.
• Presence of the original leather carrying pouch or period-correct packaging.

How to Identify Schrader Universal Tire Pressure Gauge?

• Look for the 'Schrader Universal' branding stamped directly into the cylindrical brass body.
• Verify the patent dates, which typically range from 1910 to 1923, etched on the side of the metal casing.
• Check for the internal calibrated scale that slides out from the top when pressure is applied.
• Confirm the construction is primarily brass and steel, characteristic of early 20th-century American manufacturing.

History of Schrader Universal Tire Pressure Gauge

George Schrader, the son of the founder of the Schrader valve company, patented this style of gauge in the early 1900s. These devices became essential automotive tools as pneumatic tires became standard on motor vehicles, allowing drivers to check pressure via the same valve stems Schrader also invented.
