PCTFE Sleeve,PCTFE Tube,Kel-f Tube

PCTFE,also known as kel-f, is a kind of perfect sealing material under cryogenic and high pressure conditions.It has excellent rigidity, low temperature resistance, cryogenic fluid resistance and good size stability.

• Perfect material for cryogenic applications
• Dimensionally stable over a wide temperature range
• Extremely low gas permeability.
• Excellent resistance to creep.
• Working temperature from -200°C to +120˚C

Machined parts by PCTFE (Kel-f) sleeves/tubes

Application of PCTFE sleeves/tubes

• Cryogenic applications -- super-cold refrigeration components
• Vacuum insulated piping for Liquid Nitrogen or Liquid Oxygen
• Valves -- seats, stems, seals (Butterfly Valves for cryogenic applications were developed for large pipes which are used to transport cryogenic fluids).
• Seals for lip seals with spring energizer, o-rings, v-rings, special construction seals
• Compressors & pumps
• Gaskets -- pressure, diaphragm, liquid gauge seals, fluid handling
• Bearings -- sleeve & thrust
• Stock shapes -- for machining components

• Full traceability on all material under ISO 9001:2015
• Reliable and brand raw material
• In-house tensile strength and elongation testing
• Hot size on stock and quick lead time
• With over 20 years of manufacture experience of fluoropolymers
