304 Stainless Steel Sealing Washers with Fluorocarbon Seal

Manufacturer part: 90467A208

Tested to hold up to high pressures, these washers create the strongest seal of all to lock in air and fluid and keep equipment running efficiently. They are often used on flanged connections to prevent leaks in pumps, hydraulic systems, compressors, and other pressurized lines. The flexible rubber or plastic layer compresses to fills gaps, while the metal backing stops the washer from squeezing through the hole. For Screw Heads—Fit under screw heads to stop leaks. These washers seal best on screws that aren't threaded all the way up to the head. Reuse them a handful of times, as long as the material isn't damaged.Chemical-Resistant 18-8 Stainless Steel and Fluoroelastomer—These washers resist corrosion better than zinc-plated steel, so they're less likely to rust in wet and outdoor environments. The seal withstands high temperatures and won't degrade when exposed to acids, alcohols, solvents, synthetic lubricants, and harsh detergents.
