Style N 500 ≈ Corrugated Solid Metal
--
Low pressure gasket for smooth flanges with low bolt pressure. The advantages of this gasket are its low cost and great resilience.

Style N 502 ≈ Single Jacketed with Corrugated Filler
--
Used in application which require a narrow width. This is an economical gasket that answers many needs.

Style N 520 ≈ Single Jacketed Non-Asbestos Filled
--
Generally used on narrow width applications. The single jacket protects both edges of the filler material with its metal liner.

Style N 523 ≈ Double Jacketed Non-Asbestos Filled
--
This gasket has greater compressibility and resilience than a solid metal gasket. It provides even support by the use of the overlapped jacket on the inside and outside diameters. Also, the outside lap helps to prevent distortion of lightweight flanges.

Style N 526 ≈ Double Jacketed Corrugated Non-Asbestos Filled
--
The corrugations in this gasket act as a separate seal under moderate and even bolt loads if leakage occurs across the inside edge.

Style N 527 ≈ Double Shell Non-Asbestos Filled
--
The double shell on this gasket allows greater strength and rigidity by the addition of a completely overlapping inner shell.

Style N 529 ≈ Double Jacketed Corrugated With Corrugated Metal Filler
--
The metal filler has greater resistance to problems resulting from temperature changes. The range of temperature is limited by the metal selected.

Style N 531 ≈ Two-Piece French Type
--
The soft filler is exposed on the O.D. and the size of diameter is practically unlimited.

Style N 540 ≈ Solid Metal
--
Use where a smooth flange face and high bolt load are needed. This gasket has great strength, good heat conductivity, resistance to temperature, corrosion and pressure.
