3/8 in Expansion/Contraction
Standard pipe gap, no large separation? For typical butt-to-butt CIP/DIP joining where the pipe ends are close together, the shorter-body Dresser Style 138 is the lower-cost choice and delivers the same expansion/contraction performance.
View Style 138 →
Overview
The Dresser Style 40 Long Body Coupling is an engineered mechanical sleeve coupling designed for plain-end cast iron (CIP) and ductile iron pipe (DIP) where pipe ends are widely separated — a common field condition during repairs, replacements, and installations where a standard-body coupling cannot span the gap. Structurally similar to the Style 38, the Style 40 uses a longer middle ring with a larger belly diameter to bridge gaps that would otherwise require a spool piece, additional fittings, or pipe cutting on both sides of the joint.
Despite the added length, the Style 40 delivers the same joint performance as the Style 38 — absorbing up to 3/8 in of expansion and contraction per joint — making it suitable for service subject to thermal cycling, ground settlement, or vibration. Installation requires only a wrench. No threading, beveling, or precise pipe alignment is needed.
Key Features
Bridges Wide Pipe Gaps
Extended middle ring with larger belly diameter spans wider-than-normal pipe separations without spool pieces or additional fittings.
3/8 in Joint Movement
Absorbs up to 3/8 in of expansion and contraction per joint — identical performance to Style 38 despite the longer body.
NSF 61 & 372 Approved
Certified for potable water service with Grade 27 BUNA-S gasket and fusion-bonded epoxy ID/OD coating as standard.
Tool-Only Installation
No threading, beveling, or pipe alignment required. Installs with standard hand tools directly in the field or ditch.
Angular Deflection
Allows pipe curves to be laid using straight pipe segments without bends or elbows.
Sizes 4 in – 24 in
Standard waterworks range for CIP, DIP, and PVC. Special and larger sizes available on request.

⚠ Seal Only — Pipe Joint Must Be Anchored
The Style 40 provides a pressure seal only. When pipe pullout could occur, the pipe joint must be independently anchored or restrained. Failure to anchor the joint could result in escaping line content and cause property damage, serious injury, or death. Confirm restraint requirements before installation.Consult Inside Sales For

WHERE HAVE YOU BEEN 😊
Color: Grey, Size: 34" - 3 Panel
I purchased RANTILA 3 Panel Room Divider, 6 Ft Tall Folding Privacy Screen Freestanding Room Partition Wall Dividers, 102''W x 20''D x 71''H, Grey. For outdoor use on my patio is perfect . PRIVACY!!! YAY!
It was packaged very carefully. There were no missing parts. Instructions were there but I still had to use the video visually. A few screws would not screw in. So I used a hammer with a few good taps that helped using the screw driver. 😊 It was easy putting it together following the directions. Everything is well made. Love the height, functionality and it’s definitely light it works.
Thank you

It’s really pretty decent except for one thing.
Color: Grey, Size: 34" - 4 Panel, Color: Grey, Size: 34" - 4 Panel
I bought two of these for my basement and they do look great. They were easy to assemble and I’m happy with them. The problem is that the stitching on the fabric panels are almost the size of a machine basting stitch (which for non sewers means large temporary stitches). Because the panels are tight by design, the stitches had already started to come undone before I could finish assembling everything. Fortunately I can sew and I reinforced all the panels. I had to take the first ones back off the poles to do them but I did the second set before assembling. It’s really not a bad product for the money. It’s quality fabric and the design itself looks great. The stitching looks fine but it’s just not substantial enough for the purpose it is supposed to serve. I can’t imagine why it be sewn so insufficiently. I was able to resolve my issue because I can sew. I wasn’t planning on sewing nor did I really have the time. I could have made it myself but I didn’t want to and that is why I purchased this. I ended up using valuable time. The really unfortunate thing is, I have no other complaints. This is a manufacturing problem.

Inexpensive walls.
Color: Grey, Size: 34" - 3 Panel, Color: Grey, Size: 34" - 3 Panel
We had a hot request for a workstation in the warehouse with some privacy.
These have worked great. Easy to assemble. They are lightweight and stable.
This was an inexpensive solution that looks professional. Our client loved it.

Dont wait! Assemble right away! Just in case you need to return it.
Color: Black, Size: 22" - 4 Panel
Ok, I like the idea of this but the assembly is frustrating. One side lined up perfectly with the holes however, the small bars that connect the screen to base is not lining up. I think it's do the fabric the screen or divider is made of. It's not stretchy. I brought this months ago and just opened it today. I'm upset and don't even think returning it is possible. If the material was a bit longer or stretchy to give a little room to work with this divider would be great. However, I'm not sure what I can use it for since I'm unable to attach it to the bottom. Beware! Don't wait like me. Tip for the manufacturer. Next time invest in Velcro dividers so the fabric can be adjusted with ease. Literally if I take the screen off the frame aligns perfectly. However, it defeats its purpose of privacy. I might buy some material myself and create a more flexible divider. Or I'll buy Velcro myself and attach to the bottom. I don't know yet.
