GRAPHITE RINGS

Graphite Rings are obtained by compression in a mold, based on graphite paper without any graphite component mixed, so the required density is obtained. Contain a natural self-lubricating are excellent thermal conductors and not get old or crystallize.

Graphite Rings resist a temperature of 650º. In inert atmosphere the field temperatures are -240 / +2500 ºC.

• Conform easily to the valve’s body and bonnet.
• Maintain excellent anti-extrusion.
• Require significantly lower pressure to seal.
• Can handle minor scores & pitting to sealing surface.
• Reduce maintenance costs.
• Enable easy removal without damage to the valve body.
• Are less expensive.

  • CPI-PTFE ST

    CPI-PTFE ST stainless steel lined  gaskets consist of a perforated stainless steel insert uniformly enclosed by PTFE. The synergy between the highly corrosion resistant PTFE mantle and the perfectly centred rigid stainless steel insert give the gasket exceptional chemical and mechanical properties preventing cold-fl ow in a wide pressure-temperature range. In extreme applications they are […]

  • PTFE TUBES

    PTFE extruded tubing is manufactured by high pressure PTFE dispense resin mixed with additive, it is extruded and sintered. According to different demands, the tubing could be opaque or translucent. PTFE TUBE is suitable for contact with food, according to the FDA CFR 21.177.1550 KEY PROPERTIES • High and Low Temperature Resistance: continuous operating temperature 70℃~+260℃. • […]

  • O-RINGS

    O-RINGS The use of O-rings extends to many fields. The main function that characterizes this type of joint is its ability to maintain the seal, preventing the mixture of liquids and gases. They are characterized by their versatility and resistance to high pressures and temperatures. The type of elastomer used in its manufacture can vary. We can offer […]

  • RTJ GASKETS – TG30-TG31

    RTJ joints are indicated in applications high pressures and temperatures. They are designed to be accommodated in specific slots and flanges contact surfaces of the gasket and the flange must be carefully machined and finished. They are particularly suitable for very high pressures, up to 1000 psi. The RTJ gasket material should be a little softer than the flange itself […]
