    Droog the flaired copper hose is sealing, the 1/2BSP threads are leaking i tried tightening it it's very tight so i need thread tape or a thread sealant as the top of the thread is bubbling..

    You appear to have a 1/2 compression fitting with a 1/4 BSP threaded barb screwed into it.
    If the 1/2 BSP thread is leaking it is because the flare is not sealing, the threads are not designed to seal!
    On the other hand if it is the 1/4 BSP threads that are leaking then yes use thread tape or other thread sealant.

    The adaptor that you have to accept the barb fitting, is it a compression flange on the other end or is it just a 1/4 BSP female to 1/2 BSP male threaded adaptor ?

    You may have to cut the copper pipe and fit a new compression fitting.

    Yeah you are right Droog appoligies, the flared copper pipe is leaking i have done it yup super tight with 2x large shifter's

    I may just cut the copper hose, i bought the wrong yellow/blue hose too i thought the main center oump pipe was the output which was 8mm so i brought 8mm hose but the other pipe it's connected to now is the output which is 10mm

    So i will go buy a fitting for 10mm to 14mm and some new hose and cut the brass fitting off that's leaking

    I just could'nt workout how the thread is leaking but the bottom of the fitting isn't leaking

    I just annealed the copper hose and got it to seal, i have gone over every connection with soapy water except in the switch for obvious reason's, i have gotten under the tank and sprayed the drain fittings and i just can't find a leak

    30mins of running the pump than i release the drain valve and the very tinnest his of pressure

    Do i need to remove this section from the pump? It looks like it could be a one way valve or a trap of some sort but i know nothing about fridge/air con compressors

    As per post 8
    Back to the air compressor found a lengthy video on youtube of a homemade fridge compressor air compressor, the comment's suggest the 3x pump's with the 200L tank take's 20min's to fill at 8bar 115psi
    What did the YouTuber do for the configuration in his setup, did you use the same compressor ?

    My pump is likely a goner guy's bugger, instead of air being sucked into the vent tube its blowing out i have also swapped the hoses on the pump and again it does the same thing, i will check it one last time tomorrow by swapping the hose again

    I may need to find another pump they are everywhere on facebook so quiet easy to find

    Have you confirmed which port is the suction and which is the discharge ?

    Make and model will help find some info but yours sort of looks like this.

    Looking at videos of verticle compressor pump's the top port is the discharge, the port on the side cylinder looking thing is the intake

    But i have connected the tank to both sides, i will go check now

    I just disconnected the hose and there's next to no pressure from either port on the pump

    Pump works awesome now and gee she pumps out a lot of air much more than i estimated this tank should not take long to fill but i now have a leak

    The part circled which triggers the on/off switch is leaking really bad, it's leaking right where it meets the aluminium part

    The hose isn't leaking i have removed that and trimmed the end and reconnected
