3/8" x 16 standard bolt thread.

Thanks. I was hoping it was a standard thread.

[QUOTE=Enough 4 Play;1673789]I have used this exact unit from Stevens Instrument. Probably the best one out there, it has a quick disconnect and you pump up the pressure and just let it fill the drive up. There is a valve right at the coupler to shut off the flow when drive is full. Unit is around $150.[/QUOTE


The best! +3

So where does one find a pipe with 3/8" x 16 thread that can then be adapted to the quick disconnect?
Im sure i can find a quick disconnect in my garage but i dont know about that pipe ???
I can put a nipple on the open half of the disconnect and attach it to the pump tubing but i havent seen a pipe that has the 3/8" x 16 thread that i can then attach a 1/4" quick disconnect to??

Thanks

I see your post is 5 years old, but i have to ask, did you make or buy that 3/8" x 16 pipe to quick disconnect?
Is that maybe 3/8" x16 to 1/4 npt? So a standard quick disconnect will screw on it?
I woild like to find one, tired of fighting the goofy plastic tee on the end of a pump and now i am changing a couple of buddys drive lube as well as my own.
Thanks

3/8-16 is a standard bolt coarse thread. It is not a NPT (pipe thread) Can't mix the 2 w/o ruining your threads in your drive housing.

Buy the cheapest pump unit and use the end.

I made a new end, but made it an inch longer. The ones that come with the manual pump units are usually short that they are a pain to unscrew with oily fingers unless you remove the anode behind the prop, that helps alot for better access to the drain screw threads.

I was just hoping (as in mr gadgets 5 year old post) that this was already a made up piece.
My pump isnt here at my house, so i gotta go to it to see about making tbe end into what i want.
Looks like a little time with a lathe and i can whip something up(which my brother happens to have)
if anyone happens to already have done this or knows if the quick release end from one of those commercial pumps is available seperately, give me a shout.
Thanks

so is it a standard thread...or pipe thread needed ?

yeah just buy the west marine one for 10 bucks you arent going to be able to rig something for cheaper

That is what I ended up doing. I used the wand thing from the garden sprayer I bought left the spray tip off and zip tied the hose and attached fitting end from the WM pump all together. I use the thumb lever for the sprayer as my on/off valve.
It's a super rigged contraption, but for $30 it works good enough including the drips.
