Which material is used to cover the label and hose when labeling near an engine intake?

• A. TAPE
• B. PAINT
• C. CLEAR HEAT SHRINKABLE TUBING
• D. MIL-PRF-46846 TYPE V

Answer: (D)

When labeling something near an engine intake, the protective covering over the label and hose must stand up to heat, fuels, oils, and vibration while keeping the marking legible. MIL-PRF-46846 Type V is a designated labeling product that provides a rugged, approved solution for harsh aerospace environments. It includes an outer protective layer that seals the label on the hose, resisting chemical exposure and high temperatures, and is designed for permanent, durable readability in demanding areas like engine bays. Tape can peel or degrade under heat and fuel exposure, paint can wear off and obscure information, and clear heat-shrink tubing, while protective, isn’t the standardized covering specified for this application. Using Type V ensures the labeling remains legible and compliant in those critical conditions.
