## Questions & Answers

**Q: Will it fit the  blower port that is screw on type?**
A: No, I am sorry to report.

**Q: Will this fit a vac master 6gallon 3HP?**
A: If the inside diameter of the exhaust outlet is 2.25" this unit will fit.  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. 

If you have any questions, you may call Craftsman Customer Care at 1-888-331-4569. 

Sincerely, 
Craftsman Wet/Dry Vac Customer Support

**Q: will it fit a 113177280 craftsman wet % dry vac?**
A: Hello TEA,

No, we’re sorry this muffler/diffuser will not fit the 113.177280.

If you have further questions or concerns, you may call our Customer Service at 1-800-325-1184 from Monday to Friday between 8:00 AM to 5:00 PM Central Time and we’ll be glad to assist you.

### ⭐⭐⭐⭐⭐ Review
*by S***. on 11 February 2026*

Super easy to use! Fit on my boyfriend’s rigid shop vac. I feel like it makes it less of a high pitch but doesn’t eliminate much sound. But it does stop a lot of small stuff coming out the back. Overall great addition!
