Flexitallic Flexicarb NR, also known as RGS 1, is a high-purity exfoliated graphite sheet reinforced with a 13 µm nickel foil insert. Flexitallic Product Data Sheet PDS133 specifies a polychloroprene adhesive, contrary to select legacy general guides that reference a different formulation.
Our Quebec facility manufactures custom-cut flat gaskets to your exact specifications. VAMECA can also evaluate the supply of this part number or engineer a suitable replacement.

PART NUMBER ANALYSIS
KEY COMPARISON CRITERIA
The nickel reinforcement, its low thickness, and the use of adhesive give NR a distinct construction compared to stainless steel-reinforced graphite sheets such as Flexicarb SR or FGL316.

Part Number: Flexitallic Flexicarb NR
Please provide the part number, thickness, dimensions, quantity, and process fluid. We will review material availability for the specified grade, custom cutting at our Quebec facility, or an engineered alternative tailored to your assembly.
The manufacturer's latest datasheets, certifications, and P/T curves must be reviewed prior to ordering or substitution.
The nickel reinforcement, ultra-thin profile, and integrated adhesive distinguish NR from standard stainless-steel-reinforced graphite sheet products such as Flexicarb SR or FGL316. Related reference configurations include Flexitallic Flexicarb SR (reinforced graphite), GRAPH-LOCK 3125SS (foil-inserted graphite), and Durlon FGL316 (foil-inserted graphite).
