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.

Finally sleeping through the night without waking up drenched
I was dealing with night sweats almost every night. Waking up overheated, flipping my pillow over constantly, just uncomfortable and restless. It was starting to mess with my sleep in a real way. Since switching to this cooling pillowcase (and pairing it with a cooling blanket), it’s been a completely different experience. I’m actually staying cool through the night and not waking up soaked or irritated. The fabric feels cool to the touch right away and doesn’t trap heat like a regular pillowcase. It’s smooth, comfortable, and still feels good after washing. Not stiff or weird like some “cooling” materials can be. Is it magic? No. But does it noticeably reduce overheating and help you sleep better? Absolutely. If you run hot at night or deal with night sweats, this is one of those small upgrades that makes a big difference. I wish I had bought it sooner.

so far so good
I was surprised at this pair of pillow cases only because the material seemed impossible to be cooling - it's that weird polyester blend. So far I have not awoken feeling sweaty around my face and scalp. I don't recall what I originally paid but I think it is great value for money! If you are sensitive to out of the box smell, I washed mine first and it didn't impede on the efficacy of the cooling!

It’s like sleeping on a beach in San Vito lo Capo
Italian voice: I’m a big meaty fella so I put off a lot of heat ya hear. These pillow cases have changed my life. One moment they’re hot and the next you flip them and you’re blasted with a blast of ice cool what it feels like to chew 5 gum feeling capeesh. I would reccomend these pillow cases to even my grandma. If ya wanta get a rest so good that it feels like ya been sleeping with the fishes get these pillow cases, they’re the real deal. Then stop at Pauline’s joint and grab a slice of pizza say Vinnie sent ya. Anyways I gotta go my wife’s cooking up a mean lasgna and we’re gonna watch the dodgers. Let me know how these treat ya I guarantee they will change your life. Vinnie out

Soft "cooling" case.
Yes it is very cool when you lay on it. It doesn't stay cold though. Within a minute or 2 to whatever your temp is.

Great for hair and skin. Great buy.
These pillow cases are great for my hair and skin. They look good, hold up well in the washer and dryer, and the price is great. They are cooling. Of course I wish they could be more cooling, but honestly I'm not sure that's even possible. Great pillow cases. Already bought more for other heads. Would buy again.
