2. Self-sealing fuel tank - Wikipedia

   en.wikipedia.org/wiki/Self-sealing_fuel_tank

   Self-sealing fuel tank. A self-sealing fuel tank (SSFT) is a type of fuel tank, typically used in aircraft fuel tanks or fuel bladders, that prevents them from leaking fuel and igniting after being damaged. Typical self-sealing tanks have layers of rubber and reinforcing fabric, one of vulcanized rubber and one of untreated natural rubber ...

3. Head gasket - Wikipedia

   en.wikipedia.org/wiki/Head_gasket

   Head gasket (in dark gray with a red border) sitting on top of an inline-four engine block. When installed, the four large holes will align with the cylinders. In an internal combustion engine, a head gasket provides the seal between the engine block and cylinder head (s). Its purpose is to seal the combustion gases within the cylinders and to ...

4. Fuel tank - Wikipedia

   en.wikipedia.org/wiki/Fuel_tank

   Once the soldering, brazing or welding is complete, the fuel tank is leak-tested. [1] In the aerospace industry, the use of Fuel Tank Sealants is a common application for high temperature integral fuel tanks. This provides excellent resistance to fluids such as water, alcohols, synthetic oils and petroleum-based hydraulic fluids. [2]

5. Hydrostatic test - Wikipedia

   en.wikipedia.org/wiki/Hydrostatic_test

   A hydrostatic test is a way in which pressure vessels such as pipelines, plumbing, gas cylinders, boilers and fuel tanks can be tested for strength and leaks. The test involves filling the vessel or pipe system with a liquid, usually water, which may be dyed to aid in visual leak detection, and pressurization of the vessel to the specified test ...

6. Wet wing - Wikipedia

   en.wikipedia.org/wiki/Wet_wing

   Wet wing. A wet wing (also referred to as integral fuel tanks[1]) is an aerospace engineering technique where an aircraft's wing structure is sealed and used as a fuel tank. The use of wet wings has become common among civilian designs, from large transport aircraft, such as airliners, to small general aviation aircraft.

7. Pipe dope - Wikipedia

   en.wikipedia.org/wiki/Pipe_dope

   Pipe dope. Pipe dope is any thread lubricant, thread sealing compound, or anaerobic chemical sealant that is used to make a pipe thread joint leakproof and pressure tight. [1] It is also referred to as "thread compound" or "pipe thread sealant." [2] Although common pipe threads are tapered and therefore will achieve an interference fit during ...
