APPLICATION
ACTUATORS MAN. w/NEOPRENE DIAPHRAGMS
MGM Brakes manufactures service chambers and spring brakes with “Neoprene” diaphragms for severe service applications where
petroleum saturated contaminants may enter the air system and come into contact with the diaphragms.
While “Natural Rubber” diaphragms may resist the negative effects of oil and oil saturated contaminants for a period of time, “Neoprene”
diaphragms have proven to be more durable. Manufactured from a combination of materials that insure superior strength, flexibility and
resistance to degradation due to contact with oil and other chemicals, “Neoprene” diaphragms are a great option when the air system is
prone to contamination from oil.
