Hey...I am redoing my bathrooms in my old house and the supply water to the sinks and toilets are 3/8 pipe.
i cannot find any 3/8 male going to the braided hose to 3/8 female going to supply tubing..they say 3/8 but it's larger than 3/8.Compression fittings are hard to find ..HELP

is this what you want ?

YES BUT the female end needs to be the same size as what the nut is on in this picture

*** i want to cut the chrome 3/8 line and put a compression fitting on it the 3/8 to the braided water line

so you need one of these screwed into the female end of the valve.

Respectfully Packy I think he needs one of these: [www.homedepot.com]



This will attach direcly to the chrome line via 3/8" compression on the inlet side and then he can attach the braided fixture line to the 3/8" compression on the outlet side of the valve.

I WILL LOOK ONCE MORE FOR THIS, I AM CUTTING THE SUPPLY LINE NEAR FLOOR..THEN VALVE TO 3/8 BRAIDED LINE.
NEED 4 OF THESE..

evidently the OP needs a 'coupler' to fit 3/8 PIPE


OP,

do NOT, repeat NOT cut the riser pipe from the floor UNLESS you know exactly what you are doing

you may REQUIRE one of these:

Bernabeau, chrome I assumed was 3/8" tubing, but you are correct it could be 3/8" pipe. Which if he cuts it will also need to be threaded before he can use the adapter you posted. Excellent suggestion to post a pic!

i can't imagine 3/8 OD soft tubing sticking out of the floor.
it has to be mis-communication here.
if it is indeed 3/8 chrome plated brass pipe then it should be able to be unscrewed from the fitting that is below the floor.
then replace it with a 3/8 x 6 stainless nipple with the valve i posted.

YOU ARE GOING TO SCREW UP unless you know what you are doing. POST A PICTURE because we have absolutley no idea what you are trying to do, and apparently you do not either.

Do It Best has 3/8 pipe by 3/8 compression shut off valves.
