Look at WoodRiver 2-1/2" O.D. Hose to 4" O.D. Quick-Connect Dust Collection Fitting, it appears to be more toward what you are looking for, with a female 4" and will do 2.5" or 2.25" hose connections. **Q: Can I use it to reduce a 4" pvc pipe (water pipe) to a 2-1/2" dust collector hose?** A: you would have to measure the inside and out Dia.of your pipes.and then check what this product dimensions. **Q: Will this connect directly to 4" abs pipe?** A: No, you will need a 4”coupler. **Q: I have a Jet bandsaw and the dust comes from a 4" outside dim hole I need to cover and to attach it to a 2 1/4 outside dim vac hose. Will this work?** A: It looks like the small end is 2 1/4 ID and 2 3/8 OD. The larger end is 3 3/4 ID and 3 7/8 OD.

They are good quality and they do the job. Fit is good with other product lines. Thanks ### ⭐⭐⭐⭐⭐ Great product and price *by W***N on April 14, 2026* Good product ### ⭐⭐⭐⭐⭐ Perfect Reducer With One Minor Catch *by J***Y on February 18, 2019* I bought a new Laguna 14 Twelve Bandsaw and needed to be able to connect my Rigid Shop Vac for dust collection. I purchased this PowerTec reducer because I knew it would connect perfectly to my shop vac. And I knew ahead of time that it would be the same diameter as my 4” dust port on my Laguna, so I knew it wasn’t going to simply slide over my dust port. But I had seen videos where other folks had cut a small section of 4 inch PVC pipe (Schedule 40) to use as a coupling. I did the same and it worked perfectly. I will say though that I had to lightly sand the inside of the 4” PVC pipe to reduce the wall thickness by just a hair so that it would slide on. It was not difficult at all. I didn’t have a Spindle Sander at the time so I glued a 2 inch strip of 150 grit sandpaper to a 1/2 β€œ dowel and installed it in my drill press. After running it around the inside of the PVC several times with the drill press set on medium speed, it was just enough to allow the PVC to slide over the dust port. You may not have this problem. The Laguna has an exceptionally thick powder coating finish on it which is very durable but probably also makes the outside diameter of the dust port just a hair thicker than some other brands, which explains why the 4 inch PVC needed just a tiny bit of sanding of the inside to make it fit. You can get a smaller length of 4 inch PVC at both bog box stores if you don't already have some or don't have a need to buy a full 10 foot stick of pipe. I absolutely LOVE the Laguna Dust Collection. Almost zero sawdust gets inside the cabinet or falls out onto the base. I still can't believe it. I've cut a few hundred feet of board and there is less than a teaspoon of sawdust inside the lower cabinet, and about a pinch of dust inside the upper cabinet. 99.99% of all dust gets captured through the dust port. Why other Bandsaw manufacturers have not copied their design, I will never know. Even bandsaw brands that use a tow-port design still have horrible dust collection. It makes no sense. Anyway, if you’re looking for a dust port reducer, this is the one. It’s very solid and thick enough that I would consider it to be heavy duty. Delivery was pretty good. No complaints. ## Frequently Bought Together - POWERTEC 70136 4" to 2-1/2" Cone Reducer, Dust Collection Fittings for Dust Collection Hose to Hose Connection - WEN DC1300 1,300 CFM 14-Amp 5-Micron Woodworking Dust Collector with 50-Gallon Collection Bag and Mobile Base , Black - 2 1/2" x 20' Heavy PVC Dust Collection Hose, Flexible Clear PVC Fume Collection Hose with Carbon Steel Wire Coil, Puncture Resistant PVC Dust Collection Hose for Dust Collectors with 2 1/2" Ports --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.au/products/15245457-reducer](https://www.desertcart.com.au/products/15245457-reducer) --- *Product available on Desertcart Australia* *Store origin: AU* *Last updated: 2026-05-24*
