QUESTIONS & ANSWERS
Yes. The TTL-300-ATG-I Analog Aircraft Tire Pressure Gauge is compatible with standard Schrader valves, which are commonly used on aircraft tires and many automotive-style applications. This makes it a practical tool for both general aviation and ground support tasks.
Yes. This aircraft tire pressure gauge can be used to measure nose gear strut pressure when the strut is equipped with a Schrader valve. Technicians should always verify pressure limits and follow the aircraft maintenance manual when servicing struts.
The TTL-300-ATG-I is designed to measure aircraft tire pressure up to 300 PSI. It should not be used on systems exceeding this range, as doing so could damage the gauge or affect accuracy.
Yes. This analog aircraft tire pressure gauge is well-suited for routine preflight inspections, scheduled maintenance, and hangar checks. Its straightforward design allows technicians to take quick, reliable readings without external power.
Like most precision measuring tools, the TTL-300-ATG-I should be periodically checked for accuracy in accordance with your shop’s calibration schedule. Regular verification helps ensure consistent readings and supports compliance with maintenance best practices.
The gauge should be stored in a dry, clean environment to protect internal components and maintain accuracy. Keeping it in its protective carrying case helps prevent impact damage and contamination.
Yes. The TTL-300-ATG-I is suitable for use in hangars and on the ramp during normal maintenance operations. As with any analog gauge, avoiding excessive moisture, dirt, or impact will help extend its service life.
Yes. The built-in air bleed system allows technicians to fine-tune pressure readings without removing the gauge from the valve. This feature improves accuracy and efficiency when adjusting aircraft tire pressure.
The TTL-300-ATG-I is designed with maintenance technicians in mind, making it easy to handle even when wearing work gloves. Its analog display provides clear, immediate readings without relying on electronics.
This gauge is commonly used for aircraft tire servicing, routine inspections, and nose gear strut pressure checks. It’s a reliable option for line maintenance, MRO environments, and general aviation operators.
Yes. As long as the tire or strut uses a Schrader valve and falls within the gauge’s pressure range, the TTL-300-ATG-I can be used on both fixed-wing aircraft and helicopters.
Technicians should ensure the chuck is firmly seated on the valve stem before taking a reading and avoid using the gauge on systems exceeding 300 PSI. Following the manufacturer’s instructions helps prevent inaccurate readings and unnecessary wear.
