Extension for Kitchen Sink Side Spray?

DW would like to put the spray hose hole for the kitchen sink a couple feet from the faucet, and still have plenty of length. Is there some kind of extension readily available? If not, any idea what kind and size of threads Price Pfister uses for the hose?
Thanks —

I just capped one off to install an instant hot water dispenser.
It was a Delta, but it seems that all of the older ones are generic. And there are generic replacements.
1/4" pipe thread.
Some of the new ones seem to have quick connect fittings of one type or another.
Thanks. I measured the O.D., compared the threads with a 5/16" - 18 machine screw, and looked thru the Machinery's Handbook from 1948.
The conclusion is that what I have is 1/4 - 18 NPSM, National Pipe Straight Mechanical. It's pretty much equivalent to the small end of the 1/4" NPT taper standard.

How long you looking to go?
Fisher Multimedia Stainless Steel Finish Replacement Pre Rinse Hose 96in L
Or maybe longer?
Another 2 - 3 ft. would be plenty.
Thanks for the link, it's an interesting item. But really pricey, even compared with the overpriced $68+ hose I just picked up at Ferguson's. (What a bizzarre company -- they don't stock any adapters. The clerk called the boss, and he told me that.)

Well you didn't say how$$$much$$$$.
I'm thinking you can just use a standard? 10$ or so replacement with a male to male brass fitting. Pretty standard stuff HD has a section of all those brass fittings in the plumbing department that would have it.
I'd have to look but I was thinking the connection nut was??? maybe 3/8s and fine thread not IPT, maybe the same thread thats on the supply valve to faucet and toilet.
No, it is 1/4" pipe thread. VERY close, but different than 3/8" compression fitting.That is because pipe is measured ID and tubing (which uses compression fittings) is OD.
Yes, that's basically what ended up working. I'll be returning the overpriced hose and a couple other things to Ferguson today.
The other hose was 3/8" compression female on both ends, and HD did have adapters from that to 1/4" NPT, which, with pipe dope, work OK with the 1/4" NPSM on the faucet. The shortest hose Ferguson had was 60", and HD didn't have any. So, most of it'll be coiled up and tied out of the way. The water will get pretty dizzy before it hits the dishes.... ;-)
The 1/4" NPSM that I measured was 0.525" O.D., and 18 threads per inch. Now that I have an identified specimine of 3/8" compression in captivity, I'll measure that, too. It looks to be a little smaller in diameter, and a lot finer thread.
Thread sizes for small plumbing items are sure a mess.

Side Spray Hose Connections (Typical)
A few mfgrs have switched to quick connect, but the "basic" old method still used by many is a 1/4" female straight thread for connection of hose to body. So the hose end is a female swivel connection.
If you want to add an extension, your "extender" would need to be 1/4" female straight threads to now connect to the body, and the opposite "hose connection end" would need to be 1/4" straight male threads.....so allow threading on of original hose swivel end.
Hopefully you can find appropriate parts. It might be easiest to pipe the "extension" with rigid copper tube....and end that with the 1/4" straight male adapater. Then use the original hose from there.
Take a good look at how the fittings are attached
On mine the flexible hose is attached with a crimp ring over a bayonet at the faucet end, and could readily be pulled of and inserted into a new length of hose, (which my hardware store sells by the foot), and a hose clamp substituted for the crimp ring. The other end is just a barbed bayonet fitting with no crimp.
So, salvage the fittings from the current hose, and make up a new one, as long as you want. I guess there is a limit on the length. The roll it comes on is only 250-ft long.
After 5 and a half years.............
I'm thinking John has this figured out.
I just looked at a house for a young couple b/4 they made their final offer. You could pull out the sprayer about 6 inches. Funny how those damn pipes get in the way underneath the sink.
