The pipe nipple is 1.5" male pipe thread (NPT) x 1.5" male barbed hose fitting. Do your own research on the female end of your things to see if it is a match. Or you could just order one and see if it fits, return it if doesn't.

Q: What is the total length of the 1.5 fitting?

It will vary depending on which supplier and which production lot ends up in your order. Order the correct diameter for your pipe and use Amazon's return process if it doesn't suit your needs. BTW; it is plastic and thus you can easily trim it a bit if too long.
