Style 40 Long Body Coupling
Cast & Ductile Iron Pipe

Long body bolted sleeve coupling for plain-end cast iron and ductile iron pipe in nominal sizes 4 in through 24 in. Bridges wider-than-normal pipe gaps with a single coupling — no spool pieces, no extra fittings.

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 →

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.

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.

So lightweight. Perfect for extra thick hair.
Scent: Hair Styler (1 Pack)
Its almost mousse like in how light weight it is and smells fantastic. I wanted something just above light weight hold and not weigh my thick hair down and this does a great job. A little pricey but SO much better than the usual store brands out there. And my wife is totally in love with how great it smells when I put it on, so bonus!

My boyfriend doesn’t use any skincare but this, he loves this moisturizer. It leaves his skin looking shiny and fresh. I always joke around about how it makes him look more attractive. It truly does give a glow!

Fantastic Face Wash for Men
Scent: Face Wash, Size: 5.1 Fl Oz (Pack of 2)
I love Huron's Face Wash. It is mild, moisturizing, and has just enough abrasive to exfoliate. Most Huron products are top-notch, and this is one of my favorites.

Decent face moisturizer with SPF
Huron’s SPF 30 Face Moisturizer offers a refreshing experience for daily sun protection. Unlike many other SPF products, this moisturizer does not have that overly strong "sunblock" smell, making it pleasant to use throughout the day. It's there, but it does not dominate the lotion when applied. Application goes on smoothly and absorbs quickly without leaving any sticky or streaky residue behind. One of the standout features is how it avoids that common greasy feeling often associated with sunblock. Instead, it leaves your face feeling naturally soft and well-moisturized. Ideal for anyone looking for effective moisturizer with sun protection. Highly recommended for those who want a non-oily, fast-absorbing solution for their daily skincare routine. I have previously tried Anthony Day Cream with SPF 30 and would rate this product in the same league.
