Overview

The Dresser Style 138 is a wide-range bolted sleeve coupling for joining plain-end cast iron (CIP) and ductile iron pipe (DIP) in nominal sizes 3 in through 12 in. Its key advantage is a single coupling per nominal size that covers the full OD range — whether the line in the ground is legacy cast iron or current-production ductile iron, one part number fits the joint.

Style 138 couplings provide flexible, leakproof connections that absorb vibration, accommodate pipe movement, and require no threading, beveling, or precise pipe alignment. Installation is wrench-only.

Key Features
Wide OD Coverage
One coupling per nominal size fits the full OD spread of cast iron and ductile iron pipe — from older CIP to current DIP production.
CIP & DIP Application
Engineered specifically for plain-end cast and ductile iron pipe in waterworks and utility service.
Tool-Only Installation
No threading, beveling, or pipe alignment required. A wrench is all that’s needed for a leakproof joint.
Flexible Joint
Absorbs vibration and accommodates minor angular deflection and pipe movement at the joint.

Slim profile, stays anchored all night (Berry flavor is great!)
Scent Name: Berry, Size: 100 Count, Scent Name: Berry, Size: 100 Count
I rely on these nightly to combat dry mouth, and they deliver exactly what is promised. The adhesion mechanism is impressive—once placed against the gum, the disc stays securely anchored for a full 6–8 hours without shifting, allowing me to sleep without interruption. ​The profile is ideal; the discs are incredibly slim and unobtrusive, so you don't feel like you have a bulky object in your mouth while trying to fall asleep. Despite being so compact, they pack enough moisture to last until morning. The Berry flavor is mild and soothing, making it a perfect bedside companion. Highly recommended.

Excellent product for dry mouth
Scent Name: Berry, Size: 100 Count
If you are having trouble with dry mouth, especially while sleeping, this is definitely the product for you. I have severe dry mouth and have tried multiple things including hard candy (yes, I know not very smart) as well as different biotin products, the mouthwash, the spray and the gel, which all do work, but do not last for very long. These stay in place open the corner of your mouth, last for hours and truly work. I highly recommend it if you are having a dry mouth issue
