PART NUMBER ANALYSIS

To properly select or replace this material

Graphite Reinforcement and Construction

Flexicarb LS is a flexible graphite sheet without a metallic core. It can be homogeneous or laminated depending on the supply format and retains the conformability properties of expanded graphite. The technical data sheet specifies a typical density of 1.1 g/cm³, 40% compressibility, and 20% recovery.

Applications and Thermal Limits

Flexitallic designates this material for compatible thermal and chemical applications under moderate bolt loads. The data sheet indicates -240 to 450°C, without specifying a single maximum pressure rating. Oxidizing atmospheres and exposure duration can limit graphite performance well before reaching published brochure maximums. An unreinforced sheet can also require delicate handling during narrow gasket cutting.

How to Prepare for a Replacement

Distinguish LS from stainless steel-reinforced graphites such as Flexicarb ST or SR. GP 1520 and GRAPH-LOCK 3123 serve as points of comparison for unreinforced flexible graphite, though they are not certified direct equivalents. Always verify the exact process fluid, thermal cycling, external oxidation, sheet thickness, and flange loading.

Other constructions to evaluate: TEADIT GP 1520 and Garlock GRAPH-LOCK 3123. These are performance comparisons, not direct equivalents.
