LATTYgraf EFA

LATTYgraf EFA is an expanded graphite sheet with a stated 98% purity, mechanically reinforced with a tanged ISO 1.4404 stainless steel insert, free of any adhesives or binders. Its rigidity particularly facilitates the installation of flange and valve body gaskets in hard-to-reach areas.

PART NUMBER ANALYSIS

To properly select or replace this material

Construction and Key Features

The expanded graphite is mechanically bonded to the ISO 1.4404 stainless steel tanged insert. This rigid construction is ideal for blind assembly installations and sets itself apart from homogeneous graphite sheets, adhesive-bonded flat foil inserts, and multi-layer graphite laminates.

Selecting the Right Grade

The manufacturer recommends considering LATTYgraf EFA G2F when quick flange disassembly is a top priority. When selecting any grade, take into account the atmosphere, oxidizing media, bolt load, and flange geometry. Maximum temperature and pressure ratings cannot be combined simultaneously.

To compare construction designs: Durlon FGT316 and TEADIT GE 1520. The metallic core reinforces the graphite, but its thickness, geometry, and bonding method vary by grade.
