Diaphragm material impacts welding gas regulator sensitivity, chemical compatibility, and durability. Neoprene is common for general use and provides good flexibility and control, while urethane or reinforced diaphragms are suited for higher flexibility and specialty gases. The Harris 9296-50-540 uses neoprene for improved control, while the Harris HP8700-4500-347 features a urethane diaphragm for specialized applications. Multiple material choices let you select the diaphragm that best matches your gas and usage requirements.
