Quickun Air Pneumatic Mufflers, 1/2" Male Thread Sintered Bronze Exhaust Muffler Silencer (Pack of 2)

I am using this for my diesel heater. I have this screwed into the outlet coming from my garage. I have an inline muffler and then this on the outside of the garage to help with keeping it quiet and keeping things out of the exhaust of the heater. So far it works great! Especially since I'm using it for something it's not intended for!

Purchased for work. Just what the guys needed.

Used these to make an Argon purge diffuser for when I’m welding Stainless Steel pipe. Does a much better job equally filling the pipe with the shielding gas, noticeably difference in weld quality when running hotter now.

Most of the bad reviews here failed to realize that you have to stuff them with cotton or fabric or something to muffle the sound of a pressure release. I made the mistake of using TOO much at first, so the release of air was slow, but VERY quiet. Honestly these are great.

Works better than I expected good product

Better choice for the muffler on my vacuum tank for resin projects, definitely better than the plastic one that it came with.

Great filters for the price increase my tools air capacity

works fine
