Filter Washers

Ron-Vik filter washers provide cost effective protection for faucet aerators, nozzles, emitters, valves and pumps by capturing debris that would clog or damage equipment. Our standard filters are made of T304 stainless steel wire cloth molded into Polyvinyl Chloride (PVC) or Thermoplastic Elastomers.

Gasket Materials
PVC: Black vinyl plastisol (PVC) in a 70 durometer shore A is used to manufacture gaskets that are flexible yet durable and economical. Note: If the installation puts this base in direct contact with any styrene based components please advise your customer service representative as our standard material is not recommended.

Santoprene® (TPE): Is basically an alloy of EPDM rubber and polypropylene, a colorable thermoplastic specialty elastomer suitable for use in food processing equipment and plumbing applications in contact with potable water. Complies with NSF regulation Standards 51 & 61, ASTM, ASME and EN681-2.

Mesh Materials
Standard
Stainless Steel type 304: The basic stainless alloy (18% chrome, 8% nickel) and is the most extensively used to weave wire cloth. It has excellent corrosion resistance which is satisfactory for most applications. Where no type is specified, it is assumed that type 304 is acceptable.

Optional*
Stainless Steel type 316: The same characteristics as type 304 with an additional 2% molybdenum to provide increased corrosion resistance to salts and acids. In additional it has increased strength at high temperatures.

Brass: Standard brass (copper 65%, zinc 35%) has high strength and ductility for severe cold with a mild corrosion resistance. Monel® alloy 400: A high nickel copper alloy which is one of the most widely used alloys for corrosion resistance. It has the strength of a mild steel and will not corrode in a great many solutions found in industrial applications.

Synthetics: Nylon, polyester and polypropylene offer a wide range of chemical compatibility. Only available on flat filter washers with Santoprene or other TPE gaskets.

*Limited availability and extended lead times apply to optional materials.

PVC - Polyvinyl Chloride Gasket
This is a pot-molded design as shown in fig. 1 & 2 is "self cleaning" because the cone-shaped screen is placed against the flow of air or liquid, forcing debris to the gasket area. A 5000 piece minimum applies to all filter washers. Consult your customer service representative for standard sizes and minimums on the larger sizes.

Thermoplastic Elastomer (TPE) Gasket
This insert-molded filter washer, as shown in figure 3, is a flat mesh disc with a molded thermoplastic elastomer gasket that creates a seal when placed in line. Mesh can be wire or synthetic material. The filter washers can be customized to your requirements.
