Corrosion-Resistant Mufflers
Made entirely of stainless steel, these mufflers stand up to harsh, corrosive environments. Use them to reduce noise from equipment and to filter exhaust fumes.
304 stainless steel offers very good corrosion resistance.
316 stainless steel offers excellent corrosion resistance.
