Answer: 
Yes we do. If your supply stop has 3/8” compression connections, you may like item 11K758, which is 16” long. If your supply stop has ½” compression connections, you may like item 11K756, which is 20” long. If you need a different length, please feel free to look at the offerings on page 4172, in the current catalog, number 404.

We just bought a new home and it has a claw foot tub. My husband found on Amazon a "D & L claw foot add a shower" conversion faucet to make it a standing shower. It arrived and looked like it would work with the existing Kohler (I believe) faucet- just remove the handheld shower piece and attach the new standing shower pipe. Not so easy as it turns out, the new shower/faucet is metric. Really don't want to remove the existing faucet as it is much prettier than the plain jane metric and I was really just hoping for a simple switch. Need a 3/4" female to whatever is between 1/2" and 5/8" in metric interior thread. Help please.

I have a 1" gas powered water pump. Both intake and output have a thread that we can not find a fitting for. It is a tad bigger than a 1" NPT. Do you have any information on such a type of thread?
