Style 138 Coupling

Overview
The Dresser Style 138 is a wide-range bolted sleeve coupling for joining plain-end cast iron (CIP) and ductile iron pipe (DIP) in nominal sizes 3 in through 12 in. Its key advantage is a single coupling per nominal size that covers the full OD range — whether the line in the ground is legacy cast iron or current-production ductile iron, one part number fits the joint.
Style 138 couplings provide flexible, leakproof connections that absorb vibration, accommodate pipe movement, and require no threading, beveling, or precise pipe alignment. Installation is wrench-only.
Key Features
Wide OD Coverage
One coupling per nominal size fits the full OD spread of cast iron and ductile iron pipe — from older CIP to current DIP production.
CIP & DIP Application
Engineered specifically for plain-end cast and ductile iron pipe in waterworks and utility service.
Tool-Only Installation
No threading, beveling, or pipe alignment required. A wrench is all that’s needed for a leakproof joint.
Flexible Joint
Absorbs vibration and accommodates minor angular deflection and pipe movement at the joint.

Perfect
Size: CRV 2023-26 2.0L Hybird
After having my car for almost a year and searching forever to find an air filter this one fits I've had trouble at AutoZone and O'Reilly's with them saying different conflicting things as well as the dealership but rest assured if you have the 2025 hybrid this will 100% fit it's a great value for the money the quality is the same as you would get at the dealership

Highly Recommended – Saved Big and Easy Install at 83 Years Old!
Size: CF10134&CA11476
I’ve been taking my cars to my favorite garage for over 25 years, so I trust them completely. When they quoted me $150 just to install and purchase the cabin and engine air filters on my 2016 Honda Accord, I decided to try doing it myself.
I bought this Cabin & Engine Air Filter set (fits Honda Accord 2.4L 2013-2017 and Acura TLX) for only about $27 delivered. What a difference in price!
Installation was surprisingly straightforward. Everything fit perfectly with no issues. The only extra step was doing a simple factory reset on the control panel, which was very easy and took just a couple of minutes. At 83 years old, I’m proud to say I handled the whole job myself in my driveway.
The filters seem high quality, especially with the activated carbon cabin filter. My car runs cleaner now and the air inside smells fresher. Excellent value and perfect fit.
If you’re even a little handy, don’t pay the high dealer/garage prices — get this kit and do it yourself. Highly recommended!
Would buy again without hesitation.

Perfect Fit & Performance for 2022 Explorer ✅
Size: CA10242&CF12772, Size: CA10242&CF12772
I recently installed this filter set on my 2022 Ford Explorer (2.3L), and I’m very impressed with the results. Both the engine and cabin filters were a perfect fit with no installation issues.
Performance & Quality:
Solid Build: These feel much sturdier and higher quality than the filters I removed. I bought my vehicle used, and it seems the previous owners used whatever generic parts they could find. These are a noticeable step up.
Fuel Efficiency: Since the swap, my MPG has remained rock steady at 26.1 MPG while running 89 octane fuel. It’s good to know the engine is breathing efficiently.
Cabin Comfort: The cabin air is noticeably fresh, and the airflow is excellent—no whistling or restricted feel through the vents.
Value:
Getting both filters in one set is a great deal compared to buying them individually at a local auto parts store or the dealership. I’ll definitely be looking at these again in the next 6 to 12 months for my next maintenance cycle.
Bottom Line: If you’re looking for a reliable, cost-effective alternative to dealership prices that doesn't compromise on performance, this is a great choice.

Great value and quality
Size: CF11182&CA12050
Perfect fit for turbo Civic- appears well made. I had an issue with another Honda about 4 days after I changed this and paid $28 for JUST a cabin air filter at an auto parts store. Apparently- mice like to get in there
