Featured products for Marine
Supranite V01
Made of chemically and thermally exfoliated vermiculite, that gives high-temperature properties comparable to those of compressed asbestos gaskets. It is reinforced by a ultra-thin stainless steel core.
Supranite PG VF
Made of chemically and thermally exfoliated vermiculite reinforced by synthetic fibres, in a matrix that gives higher mechanical properties than conventional elastomeric fibers gaskets at high temperature.
Flexitallic Style R
Consists of a spiral-wound metallic strip in a deep «V» with a flexible filler. The inside and outside diameters are reinforced by several wraps of winding without filler, reinforced by a suitable number of spot welds. PMUC certified.
Flexitallic Style CGI
Comprises a spiral-wound part with inner and outer rings. Preferred solution for sealing flat and/or raised face flanges. PMUC certified.
Supranite MG
High Performance Expanded Graphite Gasket. Designed to work under metal / metal contact. PMUC n°17-0200.
Flexitallic Style MRGH-V01
Comprises a serrated metallic core covered with a Supranite V01 coating.
Supranite PG XS
A restructured highly compressible modified PTFE gasket composed with only extra pure PTFE. The specific progressive structure of this quality allows high conformable faces, while ensuring maximum creep resistance. PMUC n°17-0345.
Supranite PG AC
Composed of a homogenous bundle of PTFE fibers having an isotropic structure, resulting in high level of resistance to creep relaxation compared with conventional PTFE gaskets. PMUC n°17-0156.
Supranite NGR
Made of high purity expanded graphite foils and ultra thin stainless steels laminated sheets in a multi-layer structure capable of withstanding high stresses.
Supranite NGR AS
Made of nuclear grade expanded graphite foils and ultra thin stainless steels, laminated in a multi-layer structure capable of withstanding high stresses. The graphite and stainless steel are bonded without glue by an exclusive physico-chemical process that gives outstanding cohesion. PMUC n°17-0214.
Supranite 2400
Compressed sheet material based on a blend of organic and inorganic fibers with a nitrile rubber binder system. Versatile and reliable solution.
Flexitallic Change
Its design is exclusive and provides unrivalled performance. Originally developed in direct response to customers’ long-term heat exchanger sealing problems.
Flexitallic Style RIR
Comprises a spiral-wound part with an inner ring. The inner ring acts as a compression stop. By filling the annular space between the bore of the flange and the inside diameter of the gasket, it reduces the effects of turbulence of the fluids and prevents premature flange erosion. PMUC certified.
Flexitallic Style CG
Consists of a spiral-wound part and an outer ring. The seal is made by the spiral-wound part. The external ring ensures very precise installation. PMUC certified.
Flexitallic Style MRGH
Comprises a serrated metallic core covered with a flexible coating. The profile of the grooves is specially designed according to the coating and your applications.
Flexitallic Style HX-RIR
Consists of an inner ring limiting the compression of the spiral-wound element made of a winding strip with a soft filler achieving the sealing.
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 251 VR AS
The reference for PMUC braided packing used in nuclear power control valves. PMUC n°17-0019.
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 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 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 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 NGN 02 AS
PMUC graphite tape reference. More than 20 years of positive feedbacks and returns of experience obtained from plants. PMUC n°17-0077.
Supranite NGN 03 AS
Evolution of Supranite NGN 02 AS. Can be delivered in rings, complete packing sets or boxes containing lengths (coils). Developed and qualified to reduce friction on valve stems. PMUC n°17-0393.
Supranite Packing Sets
Packing sets with Supranite NGN 02 AS or Supranite NGN 03 AS rings placed into two anti-extrusion rings in Supranite Packings 242 CP AS or 243 BF AS. Metal insert can be included inside the rings in order to facilitate future extraction. PMUC qualified.
Supranite MGM
Made from compressed graphite inserted between inner and outer stainless steel ring. Recommended for all types of application, and especially the most difficult ones. PMUC n°17-0129.
Supranite SL2
Made from compressed expanded graphite packing gasket associated with a steel backing ring. This gasket solves two major problems of valves sealing : valve opening, the need to re-machine the valve and the valve sealing surfaces. PMUC n°17-0266.
Training
« State of the art of tightening » Training with rules to follow during assembly and disassembly of bolted assemblies.
Supramet
Fabric made of silicate fibers treated by a unique compound giving it excellent performance: heat resistance, mechanical strength, and abrasion resistance. PMUC n°05-0026.
Supranite Extractors
Allows and facilitates the extraction of braided packing rings from all type of stuffing boxes.
