Leader ElastaGraph
Description
Elastagraph™ gaskets are produced by infusing seamless layers of flexible graphite at varying densities and thicknessess over a corrugated metallic core. Elastagraph™ utilizes a unique corrugated pattern which increases the depth of the groove and the pitch at the peak of the corrugation. This greatly improves the gaskets sealability over traditional corrugated designs. Available also for Heat Exchanger applications.

Product Data SheetApplication
Elastagraph™ is designed specifically to solve fugitive emission and compliance problems. It also has excellent performance in bolted joints that experience thermal cycling or limited initial bolt load. Elastagraph™ is the most economical way of meeting low emission requirements.
Advtantages
Excellent sealing against vaporous and media like gases and thermal (hot) oil.
Chemical Compatiblity
Elastagraph™ flange gaskets can be used in a wide variety of media, i.e. a pH range varying from 0-14. Application / compatibility guide is available on request. Pressure from vacuum to ASME class 600lbs and DIN/EN class PN40. Temperature from -400 ºF to 850 ºF (steam 1200 ºF).
Delivery Options
Standard gaskets are available in accordance with ASME B16.21 (1/2” – 24”) , EN12560-1 as well as EN1514-1 (DN10- DN600). Standard thickness is 1,6 mm (1/16”)en 3,2 mm (1/8”).Non-standard, or special gaskets, can be manufactured according to particular customer drawings, or by given sizes. Please note that tooling may be required.diameter of 4000 mm. We have a large stock in SS316L. Other materials are also available.
