    Works well for Woodcraft system componen

    It works well for most hose connections but doesn't fit all PVC pipe or machine dust ports. Costs add up if you require a lot of these connectors; so try to select dust collection hose, pipe and ports that do not require many of these.

    Bad size description

    I wanted to attach a flexible hose to a gate of a dustcollector. The hose side fits well, the gate side not, because it is exactly the same size as the gate. I wished the online description had exact measurements, ideally in cm for outer and inner diameters of this fitting.

    Adapter for shop dust collection system

    Good place to start. Adaptation necessary. Adapter does NOT fit snugly into any 4" PVC pipe product. Get out the duct tape and wrap to increase diameter for a snug fit. If you use PVC pipe for its smooth wall, you must consider how to eliminate static charge build up. Refer to JET book on dust collection.

    Used in 4" thinwall pvc sewer/drain pipe

    Needed to use silicone on adapter for a tight fit with the pipe.

    Excellent, well designed fitting

    Adapts nicely from 4"ID PVC to 4"hose. Connection at hose end could not be easier; simply screw the fitting into the hose. Connection at PVC end may require warming the PVC with a heat gun and massaging it to fit snugly, not too tight and not too loose. Other reviewers have criticized this product; in fact, I almost passed on ordering it. I bought 1 to see for myself, and I am reordering. This is a fine product.

    Don't waste your money...

    Don't waste your money! I bought 4 of these fittings, and within three weeks, they were all broken. For a "compression" fitting, I expected the material to be more structually sound. When I attempted to push the fitting onto a collection port, the plastic exploded into multiple pieces. Same story with the others. Completely unsatisfied with this purchase. Woodcraft should be ashamed for stocking this WORTHLESS item.

    Don't buy this adapter!

    This is a poor fitting adapter at the hard connection end. I just hope the ABS cement will fill in the space and compensate for the poor fit of the adapter!
