Supranite Packings
Supranite Packings is a comprehensive range of high-quality sealing solutions, suitable for most demanding applications.
They are specifically designed to ensure dynamic as well as static sealing on various equipments and vessels: pumps, reactors, mixers, valves, furnaces…and satisfy the most severe conditions: high temperatures, high pressures, hazardous fluids and longer operating times.

Supranite Packing 243 BF AS
Evolution of Supranite Packing 242 CP AS. Used as anti-extrusion top and bottom rings for valve stem sealing set. Developed and qualified to reduce friction on valve stems. PMUC n°17-0388.
Supranite Packing 557 EF
Developed for effective valve fugitive emission reduction. Constructed from exfoliated graphite tape reinforced with a specific Inconel ® mesh, treated with a graphited lubricant reducing frictions and a corrosion inhibitor.
Supranite Packing 545
Made entirely of thin graphite filaments having a High Specific Modulus and high mechanical properties, coated with a thin film of PTFE to facilitate fitting and running in. Increases packing-box life in most applications.
Supranite Packing 602
Made from high-density diagonal braiding of two complementary synthetic yarns : one with high mechanical strength, while the other provides excellent self-lubricating properties and facilitates the dissipation of heat generated by friction. PMUC n°17-0128.
Supranite Packing 530
Consists of very thin filaments of spectroscopically pure PTFE. Features outstanding chemical compatibility as it contains no other lubrification compound (oil,…) than pure PTFE dispersion.
Supranite Packing 601
Made from high-density diagonal braiding of synthetic and silicate yarns with high mechanical resistance. Associated with a chemically inert lubricant impregnated.
Supranite Packing 251 VR AS
The reference for PMUC braided packing used in nuclear power control valves. PMUC n°17-0019.
Supranite Packing 242 CP AS
For top and bottom rings for valve stem sealing set. Composed with an expanded graphite tape reinforced with Inconel ®. The reinforced yarns are then braided to produce this packing. PMUC n°17-0170.
Supranite Packing 557
Expanded graphite braided packing for valves, reinforced by Inconel ® wires in a specific structure that limits friction and improves the sealing performance.
Supranite Packing 660
New grade of braided packing made from an innovative organic yarn that combines high mechanical strength and limits shaft wear, associated with a dry lubrication system that increases packing-box life.
Supranite Packing 850
Produced by braiding pure calcium silicate yarn. The absence of an organic support in the production of these yarns results in a much smaller loss of volume at high temperatures than with most other products.
Supranite Packing V01
Made from chemically and thermically exfoliated vermiculite ribbons reinforced with Inconel ® mesh. This construction allows excellent handling characteristic, minimize extrusion under compressive load and improves blow out resistance.
Supranite Packing 801
Made of long pure amorphous silica filaments that do not loose weight and volume at high temperatures. Made of yarns braided in the mass, giving the product excellent mechanical resistance and ensuring a good seal.
Supranite Packing 650
Made with Supranite Packing 850 tape vulcanized for mechanical resistance and contains in its core the Supranite Packing 600. Customised manufacturing on request.
