Waterproof device for high pressure fuel pipe of fuel injection system, has connection head with rotation surface for being in support against conical recess of reception end, where surface defines circumferential groove

摘要

The device has a high pressure fuel pipe (11) and a connection head (12) on one end of the pipe. The connection head has a rotation surface (13) for being in support against a conical recess (15) of a reception end (14). The rotation surface defines a circumferential groove (19) in which a watertight joint is placed. The joint is made up of compressible material such as rubber band.
