Arrowhead Brass 458 Series Faucet Length Guide

The wall thickness is the measurement from the front of the wall to where the faucet connects to the plumbing.

Keep in mind that the fitting (3/4” Copper Sweat ID 3/4” Male Pipe Thread OD) will add 1 5/8" to the overall length of the hydrant.

If you already have a faucet, you can measure from the wall plate back to where the fitting starts to get the wall thickness like the diagram below.
