t4runnr,
Would you do me a huge favor and put a tape measure to one of your female VL4N's? I'll see what the gromets are when I get home and see if they'll fit. I would really appreciate it.
If It is a problem I'll probably just drill the holes out bigger and put my own gromets in place.
Seems like people are mostly using 1/2" tubing, so if I do that I will go with the VL4N's.
The widest part of the male is an inch in diameter. The widest part of the female is about 1 1/16".
As for the length, the female is about 2 3/4" and the male is about 2 1/4".
These VL4Ns that I have are for 1/2" ID and 3/4" OD.
