RUBBER BRAIDED HOSES
1 Buy enough hose for the job. Measure the length of each hose you intend to replace. Indicate where to cut by wrapping masking tape around the new hose and placing a mark where you intend to chop. The best way to cut the hose is with a junior hacksaw, but let the blade do the work – exert too much pressure and the hose ends may fray.
2 With the hose end (an AN fitting) securely supported, you can insert the newly cut hose using a twist-and-push motion. Bear in mind the hose needs to be inserted until it reaches the back of the socket threads. You have been warned!
3 Mark the position of the hose after it has been inserted into the hose end. This will allow you to see if the hose is being pushed out when you assemble the hose end.
4 We found it helpful to apply a little light oil inside the hose and on the threads of the hose fittings. We also used a pair of longnose pliers to ‘open’ the hose before inserting into the hose end. Ensure the hose end and nipple are treated to a liberal coating of oil to prevent snagging.
5 Check to make sure everything is ‘square’ in order to prevent cross-threading. Gently insert the hose end into the hose until the threads engage. Hold the hose to prevent it from being pushed out as the hose end is inserted.
6 Tighten both halves of the hose end together. Use the correct spanner to prevent damaging the hose end. Ensure there is sufficient oil on the threads at the point you tighten the parts. Continue to tighten the hose end until you have a gap of approximately 1mm between the two halves. For a neat finish, rotate so that both ‘flats’ line up.
7 Before you fit the hose, it’s vital to check that the hose hasn’t been pushed out of its end fitting. If all is okay, a quick clean and the removal of the previously applied masking tape is all that requires your attention. Job done!
