Assembly Instructions

Cut the flexible conduit (flex) to the required length.
(Wrap tape around the cut location before cutting.)
Without removing the tape, use pliers to cut and remove all of the braided layer that is embedded into the vinyl at the cut end. (Photo 1)
(This will make step 4 easier.)
Pass the cover nut ① and the slide ring ② through the flex.
Make sure of the direction of the slide ring.
(The thicker side should face the cover nut — see component diagram.)
Remove the tape and slide the braid back so that about 20 mm of the vinyl sheath is visible. (Photo 2)
Insert the taper ring ③ between the braid and vinyl so that the step edge of the taper ring is aligned with the edge of the braid.
Slide ring ② is then pushed up to meet taper ring ③. (Photo 3)
Cut off any braid protruding between slide ring ② and taper ring ③ with pliers. (Fig. 1)
Pass tightening ring ④ over the vinyl sheath, then screw guide collar ⑤ into the inner diameter of the flex. (Photo 4)
① Pull the cover nut toward guide collar ⑤.
(It’s difficult to perform the task if you try to pull while turning the cover nut.)
Hold connector body ⑥ in a vise and tighten the cover nut ①. (Photo 5)
Note:
The structure fixes the braid in place when the cover nut is securely tightened.
If only temporarily tightened, the braid may come loose.
Be sure to fully tighten the cover nut once.
