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.

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

Baby bumps and bodyguards
Format: Kindle
Dark, emotional, and unexpectedly tender, Not Ready is an omegaverse romance that delivers found family feels, fierce protectiveness, and a very pregnant heroine who refuses to break. Vale’s on the run from a stalker, but lands in the arms of three private security alphas, cue the swoony tension, fake marriage twist, and slow-burn heat.
It’s a little gritty, a little soft, and a whole lot addictive. If you love protective alphas, high stakes, and heroines with quiet strength, this one’s a must-read.

Strong Omegaverse Comfort and a Attention Grabbing Plot
Format: Kindle
Jillian West never misses when it comes to Omegaverse, and Not Ready is no exception. This story was the perfect blend of cozy comfort and emotional depth while still delivering a strong plot.
Vale is such a powerful heroine, she is strong, capable, and determined but I love that she still allows her pack to love and take care of her. It’s that balance of independence and vulnerability that makes her so relatable.
The relationship dynamics were amazing: Bishop is steadfast and completely head over heels, Mercy is skeptical but protective in his own way, and Holt is the hesitant one whose slow fall is so satisfying to watch unfold.
The romance hits that sweet spot between insta-love and cautious build, keeping me hooked the entire way through. And that ending. Oh my god, the cliffhanger! I need the next book in this duet immediately.

Interesting
Format: Kindle
So I will say I enjoyed the story, for sure had its moments where it dragged but it was a great story. I really liked that omegas picked their alphas/make the pack. Normally the Alphas make it and the omega fits in with them which is great but I enjoyed this new version where all the power basically went to the omega. It was a nice change of pace. I can admit some of the weird bedroom stuff with her being pregnant was odd, it’s really not hard to do stuff when pregnant (I know I’ve had two and it’s normal and even encouraged at the end especially if you want the baby out). But I like the story as a whole and will read the second, I do hope the next one isn’t dragged bc it stopped being action or tense after she met her alphas and I don’t think it was brought up or properly done when they tried to do it. More sweet after she left.
