Part Description:
The 3/8” Compression Assembly is a small plastic fitting connects the 3/8" brine line to the softener. It includes a nut, sleeve, and insert to create a tight, leak-free seal.
Function & Importance:
Attaches the small tube from the brine tank to the valve body
Keeps water and air from leaking in or out of the brine line
Allows the softener to pull in brine during regeneration
Common Signs of Issues:
Leaking around the connection
Softener not drawing brine
Salt not dissolving properly
Compatible Models:
WaterBoss 700, 900, and 950
AquaMaster 700, 900, and 950
AquaMaster PRO 5000, 5100, and 5500
Installation Tips:
Slide the nut and sleeve onto the tubing first, then insert the tubing into the port
Tighten by hand, then snug with wrench, do not over-tighten
Replace if the plastic is worn or cracked
Make sure the tubing is cut straight and clean
Why It Matters:
This small part helps your softener draw in saltwater to clean the resin. Without it, the softener may not work properly. A good seal here keeps the system running efficiently and leak-free. Please call technical support first to ensure this is the correct part for the issue your softener may be experiencing 1-800-437-8993 (EST).
