Toilet tank water connector 3/8 COMP to 7/8 BC

Model No. B28-23-38C78BC
Category:Polymer braided flexible connector
Tag:Polymer water supply line
This polymer water supply line is used to connect toilet fill valve and stop valve. It has a 3/8" Comp. inlet and a 7/8" B.C. outlet.

The nut is brass material on 3/8" Compression end. We have two choices for the 7/8" plastic nut - POM and Nylon 66. POM is more economical, but it is more brittle, while Nylon 66 is tough and more durable. Nylon 66 nut will not easily crack when tightened by wrench.
