* Burst Pressure values are theoretical values obtained by calculation. They are intended for guidance only. The burst pressure is for “spike” pressures only. For Continuous Pressures or Working Pressures take 1/4 of the “spike” pressure value listed above. Working pressures are considerably lower than spike pressures. For guidance on working pressures, consult CleanAir.
