How To Install Braided Hose Fittings – Step by Step Guide
Although the images show stainless steel braided hose, the process is the same for Aeroquip Startlite hose and Black Nylon Lightweight hose.
When cutting the braided hose to length first wrap some masking tape around the hose where the cut will take place. This serves to allow a pencil mark to define the precise position and it also helps stop the stainless steel braid from flaring out. There are a number of ways to cut this hose. The easiest way for someone cutting hose at a home workshop is to use a fine tooth saw with the hose held in some vice jaws. You could also use hose shears if you have access to them.
When cutting the braided hose with a fine tooth saw allow the blade to cut through without exerting any significant pressure. It is important to cut the hose square.
If you have any stray pieces of stainless steel braid remove them with your snips.
Insert the cut braided hose into the socket using a twisting and pushing motion until the hose reaches the back of the threads inside the socket nut.
There are a range of tools available that help to guide the hose into the socket. However, in many years of making up hoses we have never felt the need to use them. Care and attention when cutting the hose will make fitting the hose into the socket a lot easier.
Mark the position of the hose against the back of the socket nut. Wrap a piece of masking tape around the hose where it meets the back of the socket. This will act as a marker to check if the hose is being pushed out during assembly.
We find it useful to apply a small amount of oil to the inside of the hose and the threads of the socket nut. Then insert some long nosed pliers to gently open out the hose. There is no need for any significant force to be used.
Apply oil to the threads and nipple of the hose end.
Carefully insert the hose end nipple into the socket and hose until the socket engages with the hose end threads. Keep everything square to avoid cross threading. Hold the hose to stop it from being pushed out of the socket.
Tighten the hose end into the socket using the correct size spanner. Ensure there is plenty of oil on the threads as you tighten the union. Tighten until you have a gap of approximately 1mm between the socket nut and the hose end nut. Align the flats of the nuts for a professional finish.
Finally check for any signs the hose has been pushed out. Any significant movement should be investigated.
