Style 138 Coupling
Cast & Ductile Iron Pipe

Wide-range bolted sleeve coupling for plain-end cast iron and ductile iron pipe. One nominal size covers the full OD spread from legacy cast iron through modern DIP.

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.

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.

Fun toy for my dogs but squeaker broke easily
Size: X-Small, Color: Pig
So far my aggressive chewer dog hasn’t been able to rip this toy apart but in one day she did break the squeaker inside. But I like that she hasn’t been able to rip it apart so it is pretty tough. I got this on a deal so it was good price for a toy that will last. Put 1 star down because the squeaker quality wasn’t the best when she was able to break it so fast. Esp love that it has no stuffing. And it’s a cute pink pig which is great.

The cutest softest, quack, quack
Color: PINK
My seven year-old full octane energy 12 pound dog is obsessed with ducks every toy that she’s ever gotten really attached to has been a duck and I bought the same exact up from a different store at least a dozen times because she was obsessed with it. But as soon as she would get the noisemaker out of it, it was time for anyone. But it was so cheaply made I decided to start getting her different ducks that were supposed to be harder to destroy, and we still have a graveyard of destroyed ducks. But this one she doesn’t wanna destroy it. It only has one little squeaker is what I call it so she doesn’t care to try to tear it open and take it out. The material is extremely lush and soft and it is incredibly adorable. I don’t really know what makes it an interactive toy though, but I recommend it.

Puppy destroyed in days
Color: PINK, Color: PINK
My 5 1/2 month old Maltese destroyed this toy in a few days so I would definitely say it is not chew resistance.
