Bosch VAC024 Vacuum Hose Adapter for 1-1/4 In. and 1-1/2 In. Hoses

I know the ROS20VS is an older model but mine works great for what I do. Like others, I was also frustrated at the sheer number of adapters out there. It took awhile but my research lead me to conclude that this adapter was what I needed. I can say nothing about any other makes or models of sanders, but if you have a Bosch ROS20VS orbital sander, this one fits perfectly. It does take a bit to get it onto the sander exhaust port but not unduly so and the snug fit means it won't come off. The hose on my small Shop Vac has an inside diameter of 1.5125". The outside diameter of the adapter's end that mates with the shop vac hose measures 1.5305" at the end of the adapter and it tapers wider. The very slightly larger diameter of the adapter's business end, and its tapered design, allows me to push the shop vac hose over the adapter even though it's a bit larger than the inside diameter of the shop vac hose. I've used this several times and I've always been able to simply push/wiggle the hose onto the adapter and it stays on for the duration of the job. Some people commented on a non-smooth swivel action. Given that the hose is pretty well stuck on the adapter, and the fact that the adapter's attachment to the sander body is pretty well fixed also, I didn't expect any swivel action to begin with; not an issue with me. My complaints with Bosch: 1) this adapter is priced a bit high for what it entails 2) the sander came with a goofy twist-on "dust collector" cartridge that is practically useless. For the same amount of money, I think Bosch could have provided this adapter instead of the useless thing they gave me. Throw that thing away and get this adapter. Still, if you do very much sanding, this adapter is well worth the investment. I am surprised at how very little dust is NOT being collected by the sander now.

Check your tools owner manual or Bosch website for compatibility with your Bosch tool. Works fine with my GKS18V-25GCN circular saw.

Fits Bosch GSS12V-40N cordless detail sander

It fits the RO Sander GEX18V-5n, but very snug, I first I thought the inner diameter too small, but it really grips firmly onto and around the ridges of the tool. I assume that 35mm is standard Bosch sizing. The 1 1/4" side does not fit the Bosch Cordless Vac however. It did not friction fit a standard Shop-Vac 1 1/4" either. I need just one small wrap of electrical tape on the outer connector of the Shop Vac hose to snug it in; easy fix, but why does it NOT fit to a Bosch GAS18V-3N vacuum hose?

okay - there does not to be a standard with vacuum fittings. Good luck finding hoses and fittings that will work with your power tools, because all the tools are different.

I have the Bosch VAC90 and the hose adaptor fit all of my Bosch tools. This hose will not fit on any of my other tools in the shop without an adaptor of some sort. Bought this adaptor to keep in the L-Boxx that sits on top of the VAC90. This along with a variety of other Bosch adaptors allows me to connect the Bosch hose to most of my other non Bosch tools.

It works to attack my shop vac to my ros. What I didn't expect was for it to also adapt to my makita track saw and my old kreg jig. Is it perfect? No. You have to check the hose every once in a while to make sure it doesn't slip off but it does work if you can get passed that.

This stopped me from taping my normal shopvac hose to my bosch sander. Works well to 1 1/4 hose.

This works with both my Bosch Sanders and hooks to the sander very firmly and the vacuum hose stays on firmly. Also swivels so it helps to move the hose to different positions when required.

bought a new Bosch mitre saw and this push-fit into the existing dust port perfectly. Holds reasonably well

This is a bit expensive for a plastic tubing. However, the fit is perfect and helps reduce sanding dust.

Perfect fit for attaching to my 4 gallon Rigid Shop vacuum 5 HP with no other attachment pieces needed. Perfect snug fit, just sanded for hours with no issue. Sander is Bosch GSS12V-40

Would not fit the BOSCH ROS10 either end ,either male or female coupling . End with the rubber O ring seal would not fit.
