Shower hose advise

Hi Lyndon,
The hose is usually called Fuel hose, just PVC with a braid. The hose you are holding looks smaller than 18mm, it looks more like 14mm or 1/2" outside diameter. It looks 18mm where it is bulged out to fit the fitting. If it is 1/2 " outside diameter hose, its likely to be 5/16" or 3/8" inside diameter. Bunnings don't sell it but BCF do in a few sizes by the metre, its a clear hose with braid. Any other Industrial Supplier will have it too and also Pirtek . The male fitting on the end is RYCO click connect fitting, it works with water but it designed for air pressure lines so these you can get from Pirtek or an Industrial Supplier as well. The RYCO fittings also come in Brass which would suit water better.. That male RYCO fitting you have in the pic has been forced into that hose, it looks like a 1/2" diameter Barb, pushed into 3/8" hose. You can also get the fittings in 3/8" 5/16" and 1/4" to suit other hoses. If you want just an extension, Pirtek is your best bet. Take the current hose with you and you should get what you want. Pressure drop should not be an issue, most of those pumps are about 10 litres a minute at about 35 PSI so should be all good there. I hope this helps, regards Michael

I too did what you are tying to do now yrs ago on another vehicle. Extended the shower hose so l could use it on either side of the car. Its very important that it is airtight or the flow is not constant and there's nothing worse than a spluttering shower.
As previous person said, all fitting you require l got at Pertic who do Hydrolic and air fittings.
