160 VAC U U M C U P S & F I T T I N G S 6 For more information or for additional configurations, please contact us at NASInsideSales@imi-precision.com Bellows cups have a pliable outer rim that will conform to curved or uneven surfaces while the bellows sections compensate for inconsistent stack heights. Under vacuum the accordion-style bellows cup will collapse on contact. The collapsing action simulates a short cylinder stroke liing the product for a short distance, possibly saving the need for a separate liing mechanism. This bellows has a total of 2 convolutions 1 2 Single Bellows Cups (1 Convolution): NVC Style C Collapsed Height Cleat B B A D 1 Material Color Temperature Range V - Vinyl Blue +32°F to +125°F (0°C to +52°C) ORV - Oil Resistant Vinyl Black +32°F to +125°F (0°C to +52°C) P - Polyurethane Green +32°F to +140°F (0°C to +60°C) N - Nitrile Black +32°F to +194°F (0°C to +90°C) C - Chloroprene Black -40°F to +230°F (-40°C to +110°C) GS - Silicone Gray -50°F to +392°F (-46°C to +200°C) S - Silicone Translucent -92°F to +392°F (-69°C to +200°C) * How to Order: All part numbers ending with a dash require customer to specify a material type to complete part number. See Chart below for material specifications. Fittings: To order fittings, please reference the fitting groups section for the approriate part numbers. NF indicates no fitting is required. The weight of the cups shown is without fittings unless the fitting is standard ie: 1/4 NPTF. For fitting weights, see vacuum fitting section. Part Number Convolutions A - O.D. in. (mm) Approx.
