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.

⚠ 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.

Gave me hope again for my back acne
Size: 5.5 Ounce (Pack of 1)
I’ve been struggling with acne on my back since I was a teen and I’m now in my 30s and still struggling. I had taken accutane (several times) and it was the only thing that has cleared me but it always came back. I decided that I’m not gonna risk potentially hurting myself over that medication again and consistently (no matter if I didn’t feel like it!) started washing my back with this every night (even if I didn’t wash my hair). I would leave it on for at least 5 minutes and then rinse it off, then moisturize. After a month this has been the CLOSEST to clear my skin has ever gotten besides accutane. I’ve tried virtually everything. I was honestly surprised, and although it’s not perfectly clear, it’s made a significantttttt difference. It’s worth a try if you plan to be serious about it. I wish I would have taken a before picture, I just didn’t have high expectations at first!!

Can do wonders but also can completely strip your healthy skin barrier
Size: 5.5 Ounce (Pack of 1)
Awesome product ONLY IF YOU HAVE SEVERE BREAKOUTS AND OILY SKIN. STAY AWAY IF YOU HAVE SLIGHTLY DRY SKIN AND/OR MINOR BREAKOUTS- not worth the risk.
I used it for back acne and it really helped. DO NOT MIX WITH OTHER ACNE PRODUCTS.
But HUGE HUGE HUGE HUGE WARNING!!!!!——
This is NOT a great play for your face or truly anyone who doesn’t have severe acne and oily skin. Yes, it eliminates acne. If your face is extremely oil and acne prone, every few days would be fine.
I, myself, always thought my face was a mix of oily and dry- but I had a lot of hormonal acne from birth control. At first, I would use this every few days (every other, every 3, depending), and I noticed it improving my facial acne as well. I used it for 3+ months. THEN *TRIGGER WARNING* I suddenly one day broke out in HIVES. It completely STRIPS YOUR SKIN BARRIER IF YOU OVERUSE IT OR IF YOUR SKIN IS NOT SEVERELY BROKEN OUT. Red, swollen, bumps, all over my face for a week straight. My face burned so bad I couldn’t even cry it hurt. I couldn’t sleep good. Couldn’t touch my face. Couldn’t even put on moisturizer. Not even an ice pack helped. I had to stop hot showers and every single facial product/makeup for multiple weeks to heal my face. I noticed after I stopped using it, it almost made my acne better on my face- like it truly did strip my skin barrier. I will no longer be putting this on my face UNLESS I have severe acne breakouts, and if that is the case it would be a ONE TIME use. I also DO NOT use it everyday on my back or chest, it’s more of an every other- every few days type of deal.
BE ADVISED- does the job, but can also make things worse.

This is a great product!
Size: 5.5 Ounce (Pack of 1)
Edit: bleached a bunch of our towels so just be aware of that. I never understood that bc he obviously rinses it all off. But it’s definitely 100% what caused the bleaching. It’s still a good product. You just have to delegate certain towels for the person using it.
My husband uses this in addition to Bubbles anti breakout facial cleanser. They have different types of ingredients (bubbles has salicylic acid) and work well together. This combo is working well for him. He has very oily skin on his face and head. He’s also been occasionally using a facial wipe during the day (when he thinks of it) for an extra quick cleaning.
We tried several different types of cleansers and he does also sometimes use a jojoba oil cleanser before the panoxyl and bubbles. (Oil breaks down oil. Despite it sounding like it would add greasiness, it does not. Jojoba oil balances all skin types and is noncomedogenic)
This product may be enough for most of you (it’s really good!) but just wanted to mention this for anyone else who struggles with really oily skin. Of note, he doesn’t ever get acne all over his face but gets an occasional medium to large oily pimple.
I also have him exfoliating once a week with Glycolic acid) and using Tretinoin a couple of times a week. He’s supposed to be working up to 3-4 times a week but forgets.
I’m a nurse who is wound care certified so know a lot about skin and really look at ingredients and research them. I’ve also worked for a dermatologist. However, please don’t take this as advice but a suggestion to bring up to your own dermatologist or doctor. :)
I suspect when he gets up to using Tretinoin more regularly he won’t even need anything else and it will keep him from breaking out altogether.
Good luck! Don’t forget sunscreen! :)

HOLY GRAIL PRODUCT!!!!!
Size: 5.5 Ounce (Pack of 1)
Don’t let the “unaesthetic” brand & packaging fool you— there is nothing better for acne than this face wash.
I have been repurchased this face wash for almost 10 years now. I use it morning & night for acne & use it daily on my armpits for a detox. I have combination skin, so this knocks out my greasy areas & acne, & then I just go in with a heavy duty moisturizer, barrier serum & milky toner after for my dry areas.
(Side note: I used Accutane as a 16 year old for cystic back acne & a face full of tiny white zits, & this has allowed me to maintain acne free skin almost 10 years later without getting a prescription ointment.)
As for consistency & smell: It’s a white cream that doesn’t foam, & a little goes a long way. One bottle last a RIDICULOUSLY long time, unlike most “viral” face washes that last a month. It doesn’t have any added fragrance, but still smells very clean (almost like a light chlorine, which I personally love).
As for cost: It’s also priced at an EXTREMELY low cost, with Walmarts great value version only being $0.50 less expensive for a more grainy & chemically smelling wash.
!!!!!!!ADDED WARNING!!!!!: this is a 10% benzoyl peroxide cream, which is REALLY strong. You absolutely need to ease your way into using it so you don’t give yourself a chemical burn, every other day to start AT LEAST, & beware of how long you leave it on your skin. I know people with severe cystic acne that will leave it on for minutes before washing it off, but I leave it on for 15 seconds MAX or else my face gets irritated. Beware of sun exposure, & be sure to research if it interacts with other skincare products you’re currently using!
