Ammonia is also known as azane, spirit of hartshorn, and aqua fortis. It is commonly used in fertilizer production, as a refrigerant, and as a household cleaner. Common failure types of rubber when exposed to ammonia include cracking, dry rotting, and loss of elasticity. When exposed to high concentrations of ammonia, the rubber may become brittle, swell, and eventually disintegrate.
