Corrosion-Resistant Breather Vents
304 Stainless Steel
303 Stainless Steel
316 Stainless Steel
These breather vents withstand corrosion in damp environments. Use them to prevent excess vacuum and pressure in cylinders, gear boxes, and tanks and to block debris from entering equipment.
Stainless steel breather vents stand up to higher temperatures than polyethylene breather vents. Those with a Viton® fluoroelastomer O-ring offer extra protection against leaks. 316 stainless steel breather vents resist corrosion better than 303 and 304 stainless steel breather vents.
