as title ,

looking to tap pout and fit jic fittings to my block and some other parts on the engine

just wating to know what the correct size taps would be for standard jic sizes

an 6
an 8
an 10
an 12
an 14

are they simpy metric threads or unf ect


anyone shed some light for me

 

I'm sure I looked at these on t'internet and they were metric,do you have a link though?I could tell you straight away then as some maybe metric fine etc.

 

-6 is 9/16 x 18 unf
-8 is 3/4 x 16 unf
-10 is 7/8 x 14 unf
-12 is 1.1/16 x 12 unf
-14 is not a typically used size
-16 is 1.5/16 x 12 unf

 

cheers jon , are they 100 % unf , or do they have a metric equivilant

 

they are indeed 100% unf

 

Surely this would depend on the fittings used, I know on all the hydraulic stuff at work that uses jic fittings its normaly either npt-jic or bsp-jic fittings when going from a block to a hose.
It would also depend if you are using stepped fittings eg 3/8npt to jic12 or a straight size fitting would be a 3/4npt to jic12.

 

 

as said above i always got weld on adapters or NPT / bsp fittings to connect the quip stuff up.

 

your correct neil it prob would , i just wanted to know if they were metric based or unf ect ,


saying that i looked on torques website and they sell a metric to jic adapters anyway , iirc m16 to -8 jic ,


thanks for the info guys
