摘要

PURPOSE: A rubber product and a regulator are provided to have the same low-temperature characteristic as a nitrile rubber, since a rubber product is a valve body or a diaphragm mounted on the regulator. CONSTITUTION: A rubber product is composed of quaternary fluorine rubber obtained by the copolymerization of VDF, HFP, PAVE, and TFE. The rubber product is a valve body(241) of a valve or a diaphragm(21), mounted on a regulator constituting a fuel feeding system.
