THE PROTEK HAND DIAPHRAGM PRIMER #5 contains a rubber diaphragm working in an aluminum chamber. A levered handle attached to it by a connecting rod actuates the diaphragm. Air is drawn into the chamber through a suction valve on the up-stroke and discharged through a discharge valve on the down-stroke. The diaphragm is of molded rubber, and it is extremely tough and long wearing. A rubber air discharge valve, built into the diaphragm, provides a positive seal.
