Hi, I want to fit one of these to my 07 Ultra. Does anyone have the thread size? I am in the Uk and am having trouble sourcing. Thanks

 

1/8" pipe......?

 

1/4-28 tapered thread.

1/4-28 is correct. Here you have to buy a selection of straight, 45 and 90s.
The 90 would work better with a standard gun but I couldn't get it to fit on my 07.

 

I believe they are 1/8 NPT's.

 

1/4-28...SAE thread(its not pipe thread)

to get the 90* ones on you hafta take it apart...put the threaded end in, then screw the nipple back in...


1/8" pipe is way too big...

 

ok,1/16 ?

 

Uh no. 1/16 pipe is still larger than a 1/4-28
Pipe thread sizes are based on the inside diameter And TPI is wrong
A 1/16 pipe thread is 27 TPI
TPI = threads per inch
The diameter of a 1/16 pipe is 5/16

Ok, ok, I went out and checked the box to make sure. It is in fact 1/4-28.
Also thanks for the tip, I didn't realize you could unscrew the nipple on a 90.
I tried it. Next time I grease, the 45 is coming out and in with the 90.

 

Ok .......
