These economical fittings will help you build a high performance dust extraction system for your shop. Made of ABS plastic (except for the aluminum blast gates), these fittings are designed to stand up against the abrasive nature of saw dust and wood fiber. Universal Tool Adapter adapts your wet/dry vacuum hose to stationary or portable power tools. It's constructed of a tough material and conforms to slight variations in size. The "stepped" design contains a 1", 1-1/4", 1-1/2" and 2" external diameter and a 1-1/4", 1-1/2" and 2-1/2" internal diameter connection. It also has a square flange with mounting holes that can be used with a collection box. Because of the danger of static electricity involved with dust collection we highly recommend the book Dust Collection Basics #85O17 to be read prior to any installation.

    Inexpensive, but limited application

    These are good alternatives to the expensive metal elbows. I use them for a shop-built cyclone lid that fits on a 30gal metal trashcan. They hold up great and I have not noticed any significant loss of pressure using them. I have only tried using them with the 4" clear dust collection hose because they do not look like they fit well into the spiral pipe. Break down and go metal to metal, but use these inexpensive elbows where you are running 4" DC hose.

    Positive Connection Needed

    There's nothing wrong with this dust elbow, or any of the other plastic parts sold here. They're durable; they fit. I wish, however, that someone would come up with a way to make the plastic-to-plastic connections more secure. I'm using this elbow to connect the vacuum hoses to the 2-stage trash can lid, and any movement of the hoses will cause the elbow to disconnect from the lid. I also found the elbow that connect inside the trash can to have fallen off. Must be a better way...

    I would buy this product again

    I am using the elbow on a pre separator.
