Sealing Technology
Bar Tite

1

Upward

to seal the underside of the fastener and washer hole

2

Outward

to seal the contoured underside of the washer and the surface of the fastened material

3

Downward

to seal the clearance hole and threads of the fastener

What makes BarTite unique?

BarTite washers employ a proprietary PVC plastisol sealant that is unlike ordinary molded or sheet rubber compounds, which only create static seals. The plastisol is applied as a viscous material that adheres to the metal washer and thermally sets. The result then compressed is a sealant that flows in every direction to fill all gaps, creating a truly dynamic seal.

Stainless Steel - What are the benefits of using 316 Stainless Steel?

What differentiates 316 Stainless Steel from 304 Stainless Steel?

The composition of Type 316 Stainless Steel includes slightly increased nickel content and the presence of 2%-3% of molybdenum, which significantly increases the metal’s corrosion resistance.

    Where would I use 316 Stainless Steel?

    The use of 316 Stainless Steel is ideal in coastal areas, marine applications subject to sea sprays, industrial equipment exposed to corrosive process chemicals, and any area subject to high exposures of chloride (including de-icing salts).

      What are some of the benefits of 316 Stainless Steel?
      The unique composition of 316 Stainless Steel provides improved performance in many areas, including:
      • Superior Resistance to Chloride
        Corrosive salts can be present in many areas of the country. In addition to coastal areas, sea sprays, and salt in rain water, heavy exposure to chloride can also be present in many parts of the country that use de-icing salts on roadways. Salt-laden roads in colder climates can sometimes create even heavier salt deposits than coastal areas. The de-icing salts become airborne via dust and road mist that allows them to travel significant distances from busy roads and deposit on surrounding structures including buildings, exterior furniture, lampposts, etc.
      • Resistance to Corrosive Chemicals
        The addition of molybdenum increases the metal’s resistance to acetic, sulfuric, and sulfurous acids as well as many industrial chemicals and solvents. These types of corrosive process chemicals are used to make a wide variety of products including inks, textiles, photographic chemicals, paper, textiles, rubber, and bleaches.
      • Better Resistance to Cracking & Pitting
        316 Stainless Steel offers a reduced risk to stress corrosion cracking, improved creep resistance, and better protection against pitting and crevice corrosion.
      What are some common applications for Type 316 Stainless Steel?
      • Marine environment applications – (*with the exception of fasteners that require better strength & wear resistance versus corrosion resistance).
      • Coastal area structures and exterior products.
      • Architectural structures and exterior products found in colder climates where significant amounts of de-icing road salts are used.
      • Industrial equipment that handle corrosive process chemicals used to make such products as inks, textiles, bleaches, photographic chemicals, and rubber.

      BarTite Washers without Sealant

      Stainless Steel Washers are available without the plastisol sealant, and will collapse under pressure.

        Applications and Benefits:
        • Can be used as a spacer, shim, or traditional washer with adjustable thickness
        • The overall height will reduce to washer thickness as pressure is applied
        • Can control surface contact area and reduce wear/abrasion on plated, painted, and finished surfaces
        • Customers report using these washers to create a better seal with some non-metal surfaces
        To Order:

        Request BarTite part numbers with “B” at the end. (Examples: RS62200B, RSCM10B)
