Description

Elastagraph DS gaskets are produced by infusing seamless layers of flexible graphite at varying densities and thicknessess over a corrugated metallic core. Then ePTFE is applied to the I.D. portion of the corrugated core with an 1/8” overlap. Elastagraph DS 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.

Product Data Sheet

Application

Elastagraph DS is designed specifically to solve fugitive emission and compliance problems. Combines the chemical resistance of ePTFE and graphite that is fire safe. It also has excellent performance in bolted joints that experience thermal cycling or limited initial bolt load.

Chemical Compatiblity

Elastagraph DS 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 patricular customer drawings, or by given sizes. Please note that tooling may be required.
