Thread grommet 1/4"r ext. x 4mm

The 1/4" thread has a hollow cone. Hose grommets 914005 to 914008 with a cold seal fit on this, so that 2 hoses can be easily connected or disconnected. Threaded grommets are also often mounted in an internal thread with Teflon tape or they are glued in. A 4 mm (lilliput) hose must be mounted on the grommet with a hose clamp or a press sleeve.
