Hi, ive bought a terrafirma braided hose set and when fitting the single hose to the rear axle ive come across this (see pic). The tee piece looks like it needs a male connection but the braided hose has a female. Will it still seal or am i missing something? Can i put anything on the thread to form a seal i.e. Ptfe?

Ok threads on out side are male
threads inside are female

I understand that but the male on the braided hose looks like it needs a bulb on the end otherwise when they tighten they will only be sealing on the thin edge of the male. Is this right?

No a machined boss to receive the shoulder on it, should be. use Teflon tape on the threads before assembly seals the threads and makes it easier to undue( stops then from rusting together)

Can you see how the other end of the hose with the longer thread has a bulb on the end, it looks like i need this end for the tee piece but i need the longer thread to go through a mount on the boot floor crossmember

are the ends the same as what you took off? if they are then should work. If not they sent you wrong stuff.

t pieces have different sealing surfaces some female with concave surface some female with convex surface which your pipe is for you need to look in t piece to be sure

ok thanks, it is fitted at the moment, i was just gonna fill up and test it when all the rest of the work is completed. im pretty sure its concave inside the tee piece which is why im concerned because in my mind (being a plumber) two concave's meeting together wont seal but i may be wrong as i mainly use olives for connection, the only time i use a flaring tool is on oil lines. all this mechanical malarchy is still new game at the moment

the seal is normally on the taper on the end....and not on the threads....but that relys on having mating tapers on the two parts. proper bsp threaded hydraulic fittings have tapers whereas bsp threaded plumbing fittings dont.... i have joined the two in hydraulic systems by using ptfe tape on the threads.
the only other way of getting a seal is to use a bonded washer...basically a metal washer with a rubber seal in the hole... sandwiched between the nut bit on the male fitting and the end face of the female fitting... doesnt blow out under pressure like an o ring would
