Fits CRAFTSMAN wet/dry vacs with a 2-1/2 in. diameter blowing port. Review: Works Fine - I saw this featured in a YouTube video to reduce the noise of a shop vac AND diffuse the blowing action from the blower port of the shop vac. The blower port had always been a frustration for me in my woodworking shop because it blew all the fine dust particles everywhere. This adaptor diffuses the blast of exhaust air so it partially eliminates the problem AND make the shop vac a little quieter, too! Review: Best at filtering dust - Excellent at filtering dust. I've had mine on my shop vacuum for 4 years now and it keeps working. Like other reviewers have noted, it's not really a muffler but is excellent at keeping the dust in the vacuum. I use my vac in the basement and before this device I rarely used may shop vacuum because it made a bigger mess than it picked up. So for the price, especially if your using a shop vac inside get one of these. ## Features - QUIETER OPERATION: Vac muffler diffuser helps reduce air noise for quieter operation - REDUCES BLOW BACK: Diffuses wet dry vacuum airstream to reduce blowing debris and dust - EASY INSTALLATION: Connects to the blowing port of the shop vacuum - INDUSTRIAL-GRADE CONSTRUCTION: CRAFTSMAN wet dry vacuum attachments are built to handle heavy use - FITS: CRAFTSMAN wet/dry vacs with a 2-1/2 in. blowing port ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01HZWFLH2 | | Best Sellers Rank | 291,504 in Garden ( See Top 100 in Garden ) 699 in Blower & Vac Accessories | | Brand | Craftsman | | Brand Name | Craftsman | | Colour | Black | | Country Of Origin | Mexico | | Customer Reviews | 4.6 out of 5 stars 4,016 Reviews | | Filter Type | Cartridge | | Filter type | Cartridge | | Form Factor | Accessory | | Global Trade Identification Number | 00648846007045 | | Included Components | 2-1/2 in.

On Craftsman Vacuums there is a plastic ridge on the outside of the exhaust port which will keep the muffler from sliding off. If the Vac Master doesn't have this ridge, you may want to tape the muffler to the exhaust port. **Q: Is it possible to buy the foam replacement rather than the entire unit?** A: Hello willcee, We’re sorry the foam is not available as a separate item.
