Bellow bodies contain nylon chord fabric reinforcements in order to withstand high pressures, and provide structural integrity. Bellows up to 300nb are rated for 1600 kpa working pressure, while larger sizes are rated for 1000kpa.
The addition of the Truco bellows range has been met favorably by the market, with large orders from mines across Africa.
