Overview
The Dresser Style 38 is a bolted mechanical coupling engineered for flexible, leakproof connections on steel pipe in water, wastewater, and industrial piping systems. No threading, beveling, or precise pipe alignment required — installs with standard wrenches only.
The resilient gasket design absorbs vibration, accommodates thermal pipe movement, and allows angular deflection — enabling curves to be laid using straight pipe lengths without bends or elbows. Compliant with AWWA C219.
Key Advantages
Tool-Only Installation
No threading, beveling, or exact alignment required. Installs with standard wrenches directly in the field.
Absorbs Pipe Movement
Resilient gaskets absorb vibration and accommodate thermal expansion and contraction at the joint.
Angular Deflection
Permits angular deflection — curves can be laid with straight pipe, reducing fittings cost and labor.
½ in to 48 in Standard
One product line covers virtually any plain-end steel pipe application. Larger custom sizes available on request.
Fusion-Bonded Epoxy
Standard coating provides superior corrosion protection in buried, submerged, and aggressive service.
All-Stainless Option

⚠ Seal Only — Pipe Joint Must Be Anchored
The Style 38 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.Installation — Step by Step
No special tools required beyond a torque wrench and basic hand tools.
- Pipe End PreparationClean all dirt, rust, oil, and loose scale from pipe end. Inspect gasket seating surface — any gouges or grooves must be corrected before assembly.
- Mark Center PointsMeasure back on each pipe end: ½ the middle ring length plus 2 in. Chalk mark both ends to center the coupling over the joint.
- Position FollowersSlide the follower(s) over the pipe end(s) before assembling any other components.
- LubricateWipe gaskets clean. Lubricate each gasket, pipe OD, and middle ring flares with soapy water or non-petroleum lubricant. Use antifreeze in freezing weather.
- Assemble Middle RingSlide lubricated gaskets over each pipe end, then assemble the middle ring onto one pipe end.
- Join Pipe EndsStab second pipe end into middle ring. Center between chalk marks. Pipe end must extend past end of gasket by minimum 1 in after any angular deflection.
- Install FastenersInstall all bolts and hex nuts. Draw up finger tight before torquing.
- Torque SequenceTighten nuts on opposite sides in a cross-pattern, drawing followers up evenly. Do not fully torque one side before the other.
Torque Specifications
| Bolt Diameter | Required Torque (Ft. Lbs.) |
|---|---|
| 3/8 in & ½ in | 35 |
| 5/8 in | 75 |
| ¾ in | 90 |
Important
For single-gasket products, reduce all torque values by one-half. Stainless steel bolts must be lubricated before installation to prevent thread galling.

Eradicated Decade Long battle with KP on INNER KNEES in less than 1 week. NEW KP HOLY GRAIL CREAM!!
Scent: Sweet Vanilla & Soft Wood, Size: 10 Fl Oz (Pack of 1)
About my skin- 43 year old fair, normal to dry, very sensitive, prone to KP bumps on back of arms, inner knees and if aggravated - all over thighs. I am pretty careful with what I use and I even have to be careful within the same brand if something DOES work. I have spent a long time being snobby about “drugstore” brands because over the years they have all aggravated my now mostly under control KP. I recently was convinced to try the Olay SUper Serum body wash because a friend with similar issues said she was really impressed. I have been also! In fact, the body wash for “Rough and Bumpy” skin has been my go-to wash for the past few months and has visibly improved my overall skin texture and has not aggravated any KP flare ups. I was very excited to try this body cream, since the current one I use is over 50 dollars for a similar size jar. I like to use A LOT of moisturizer and the cost is really annoying and close to being prohibitive when you use a jar a week. I purchased this cream (packaged well, no leaked, fresh product, overnight delivery). I am in LOVE! It smells great, very high end. The fragrance is real so if you hate fragrance, bot for you. I wear Baccarat Rouge and this lotion does not interfere with that, and it does dissipate after a while (I asked others to be sure). The crazy thing is this… most of the time my KP bumps on my inner knees are there, but when I have them under control they just lack color and are a lot smoother. THEY ARE GONE AFTER 1 WEEK.. THIS IS THE FIRST TIME IN THE DECADE OR SO I HAVE HAD KP BUMPS ON MY INNER KNEEES THAT THEY HAVE BEEN COMPLETELY GONE. I do not feel it is the combo of the wash and this cream, as I have been using a different wash while out of town. The only new item I used was THIS CREAM, alone, without my other more expensive product. I am kind of blown away and delighted. Also, I was able to use less of this to feel moisturized than I have been using with the “fancy” brand. The scent is warm, slightly vanilla, expensive and not too floral. Cream absorbs quickly and well, leaves skin feeling plumped, soft, no greasy residue and MAJOR BONUS… NO PILLING. That is a nightmare when a product does that. It absorbs quickly, leaves no marks on clothes when squeezing into a pair of black legggings…. All the good stuff you may forget to look for but notice when they happen. I HIGHLY RECOMMEND TRYING, if a light, high end fragrance is good with you. To reiterate- the fragrance is not crazy strong but it also calms WAY down about 30 mins after applying and melts into just a nice feminine clean but warm (not body spray type of vibe) scent that is not very noticeable to me or others. No where near as strong as like a Bum Bum cream (which I LOVE IN SUMMER) and smells high end, not like cheap shampoo or air freshener. Get this!!!!!!! It also did not irritate my chest area which for me is always a little prone to red spots when I use fragranced products. No irritation and dude… NO BUMPS FOR FIRST TIME IN A DECADE OR MORE. WOW!!!!

THE BEST LOTION I HAVE EVER USED
Scent: Sweet Vanilla & Soft Wood, Size: 18.5 Fl Oz (Pack of 1)
THIS WINTER AND HAVING THE HEAT ON HIGHER THEN I NORMALLY DO HAS DONE A NUMBER ON MY SKIN. IT IS SO DRY AND I HAVE TRIED SO MANY THINGS AND NOTHING HAS REALLY WORKED. SO I GAVE IN AND SPENT THE MONEY AND TRIED THIS. I AM SO GLAD I DID. THIS WAS WORTH EVERY PENNY. I LOVED IT SO MUCH I BOUGHT ANOTHER BOTTLE JUST TO HAVE SO I WOULDN'T RUN OUT. I START OUT WITH THE BODY WASH WITH THE OLAY SUPER SERUM BODY WASH AND JUST AFTER ONE WASH MY SKIN WAS MUCH SOFTER AND SMOOTHER. YOU DO NOT NEED A LOT AS IT LATHERS UP NICELY IT SMELLS GREAT AND IT RINSES OFF GREAT LEAVING YOUR SKIN FEELING CLEAN AND SOFT. IT DOESN'T HAVE A STRONG SCENT TO IT WHICH IS FINE . I FOLLOW IT WITH IT WITH THIS SUPER SERUM LOTION JUST TO MAKE SURE THE SKIN STAYS SOFT. THIS LOTION IS SO SOFT AND SILKY. IT ABSORBS QUICKLY INTO YOUR SKIN WITHOUT LEAVING YOUR SKIN FEELING GREASY. IT IS LIGHTWEIGHT AND LEAVES YOU FEELING SOFT WITHOUT THAT DRY CRACKED APPEARANCE. THE SCENT ISN'T VERY STRONG TO ME WHICH IS FINE BECAUSE I WEAR PERFUME SO I DO NOT HAVE TO WORRY ABOUT THE SCENTS MIXING. I DEFINITELY RECOMMEND THIS REGIMEN TO ANYONE SUFFERING FROM DRY SKIN.

4.5/5; Great product, but smells strong
Scent: Sweet Vanilla & Soft Wood, Size: 10 Fl Oz (Pack of 1)
Context:
To start off, I should say that I have dry skin. Like, VERY dry skin. In purchasing this item, I wanted a product that I could consistently apply every single day to hydrate my skin.
Product:
The application of this stuff was like a dream. If you’ve ever tried using ANY sort of lotion (Lubriderm, Cetaphil, etc.) you’d know that usually it leaves that greasy texture on your hands that you have to wash off. This one doesn’t do ANY of that. The cream melts into your skin and absorbs very easily, unlike other lotions. I didn’t need that much to apply to my entire body. The results were great—my skin looked better and felt softer. If there was to be a con, it would be how strong the fragrance of the lotion is. This stuff smells STRONG. It’s not an unpleasant scent, but if you wanted to wear a perfume or body spray along with it, good luck because I can’t see a world where the cream won’t overpower or at least show through your preferred scent.
TLDR
Overall, good product with dreamlike application, but strength of scent could be dealbreaker for some.

This everyday body lotion is the bomb!
Scent: Collagen, Size: 17 Fl Oz (Pack of 1)
This body lotion is absolutely fabulous! It really does make the skin on my thighs and abdomen look and feel firmer and the skin on my arms, legs, hands, and feet is noticeably softer and more hydrated without looking greasy or feeling sticky. I even use it on my neck and my face, which has tended to be more dry than oily as I've aged. I also really appreciate that the scent is pleasant enough to stand on its own but subtle enough to work well with other fragrances. I don't think that I have ever been this satisfied with a health/beauty product at such an affordable price point. I even purchased a few extra bottles to gift to friends and family.

Wow - my new favorites 💜👍😀
Scent: Retinol, Size: 17 Fl Oz (Pack of 1)
I just purchased this and tried it last night for the first time along with the firming version. I didn't take photos because I was skeptical as a product I had purchased from a different line for more money didn't work. This morning I notice that not only does my skin feel more hydrated but the texture appears more smooth. I recently turned 75 & lost my husband a few months ago and having been a care giver for awhile and put taking care of me aside. These products and body wash are great and I like the fragrance.
Please give them a try. To have something show this much difference over night is incredible. They are also affordable which is a plus for me. Thank you Olay.
