PTFE hoses and fiitings for PTFE hoses

Polytetrafluoroethylene (trade names: tarflen, teflon, fluon) has been known as a material for more than 60 years. Due to unique qualities, it is widely used in all branches of industry including production of flexible hoses of various structure and usage. General qualities of PTFE:

  • exceptional chemical resistance – only a handful of substances affect PTFE
  • wide range of temperature resistance (from -70°C to +260°C)
  • very good aging and weather conditions resistance
  • self cleaning properties - substances do not stick to hose walls

Hoses are manufactured not only from PTFE but also from PTFE copolymers (FEP, PFA, MFA, ETFE, ECTFE) with similar to PTFE properties but increased mechanical resistance and processing qualities.
PTFE, and PTFE copolymer hoses are widely used in all branches of industry for steam, hot oil, fuel, paints, adhesives, technical gases, chemicals, acids, solvents and bases to name the most important ones. PTFE hoses ensures high level of hygiene and thus are used in food, cosmetic and pharmaceutical industry.

For PTFE and PTFE copolymer hoses see: hoses for high pressure gases, chemical hoses, ducting hoses.

PTFE hoses without braid

PTFE hoses without braid

PTFE hoses without braid designed for unpressurised or low pressure applications. Available as smoothbore or corrugated (more flexible but with reduce flow rate) versions. Semi-transparent wall allows visual control of medium being transferred. Designed for industrial applications, in food, pharmaceutical and laboratory applications. Depending on the pressure, can be assembled with the use of clamps or crimped with ferrules.
SMTO, CHEMFLUOR PTFE – smoothbore PTFE hoses – DN from 2 to 18 mm.
FXTO – corrugated outside, smoothbore PTFE hose - DN from 6,8 to 26,3 mm
CHEMFLUOR FEP – smoothbore FEP hose– DN from 2 to 12 mm.
CHEMFLUOR PFA – smoothbore PFA hose – DN from 2 to 10 mm.
PHARMALEX - corrugated outside, smoothbore PTFE hose, with transparent silicone cover - DN from 6,8 to 25,4 mm.

PTFE BRAIDED HOSES - SMOOTHBORE

PTFE BRAIDED HOSES - SMOOTHBORE

Smoothbore PTFE hoses with stainless steel (or different material) braid reinforcement designed for working pressure till 400 bar. Widely used in all branches of industry as hose assemblies with crimped fittings.
SMOOTHBORE – smoothbore PTFE hose with stainless steel braid reinforcement. Crimped with special type of fittings (modified hose tail to suit PTFE hoses). DN from 1/8” to 2”, working pressure to 380 bar.
HYPERLINE SB – smoothbore PTFE hose with stainless steel braid reinforcement. Crimped with standard hydraulic fittings. DN from 3/16” to 1”, working pressure to 320 bar.
CHEMFLUOR TH – special, high-pressure, smoothbore PTFE hose with stainless steel braid reinforcement. Crimped with special type of fittings. DN from 5,6 mm to 22 mm, working pressure 345 bar for all hose diameters.

PTFE BRAIDED HOSES - CORRUGATED

PTFE BRAIDED HOSES - CORRUGATED

Corrugated PTFE hoses with stainless steel (or different material) reinforcement. Highly flexible and widely used in all branches of industry as hose assemblies with crimped fittings.
VISIFLON (HYPERLINE V) – corrugated outside, highly flexible PTFE hose with stainless steel or polypropylene braid reinforcement. Crimped with special type of fittings (modified hose tail to suit PTFE hoses) or standard hydraulic ones. DN from 3/8” to 2, working pressure till 60 bar.
HYPERLINE FX – corrugated outside, smoothbore PTFE hose with stainless steel or aramid (Kevlar) braid reinforcement. Crimped with standard hydraulic fittings. DN from 1/4” to 1”, working pressure till 88 bar.
PHARMALINE - corrugated outside, smoothbore PTFE hose, with white silicone cover. Crimped with special hygienic fittings. DN from 1/4” to 2”, working pressure till 130 bar.

FITTINGS FOR PTFE HOSES

FITTINGS FOR PTFE HOSES

Depending on PTFE hose type differnt types of fittings (for crimping) are used:

  • SMOOTHBORE and HYPERLINE V (VISIFLON) - special fittings and ferrules for PTFE hoses.
  • HYPERLINE SB, HYPERLINE FX and HYPERLINE V (VISIFLON) – standard fittings for hydraulic hoses and ferrules for PTFE hoses.
  • PHARMALINE and PHARMALEX – special hygienic fittings and ferrules for this particular hose type.
  • CORROFLON and BIOFLEX – special fittings and ferrules for this particular hose type - described in more details in the chapter concerning that hoses.

Fittings and ferrules made of carbon steel, stainless steel AISI 304, AISI 316, polypropylene or different materials. Available with all types of connections: metric, hygienic, flanges. On request custom made items - according to customer specifications.

CORROFLON AND BIOFLEX HOSES

CORROFLON AND BIOFLEX HOSES

Highest quality PTFE hose, designed for the most demanding applications. Widely used for process applications, reloading of the most aggressive chemicals, food and pharmaceutical products. Main advantage of CORROFLON hose is ability to supply this hose as a hose assembly with PTFE lined fittings. PTFE layer is extended through the fitting and flared over the sealing face. This construction prevents any contact of the transferred medium with the material of a fitting what ensures the highest degree of hygiene (lack of crevices). CORROFLON and BIOFLEX are supplied as hose assemblies in many versions (i.e. with rubber, silicone or flame resistant cover) and many types of fittings.
CORROFLON – helically corrugated PTFE hose with stainless steel wire helix and stainless steel or polypropylene reinforcement. DN from 1/2” to 6”, working pressure till 41 bar.
BIOFLEX – Smooth inside, corrugated outside PTFE hose with stainless steel or polypropylene reinforcement. DN from 3/8” to 2”, working pressure till 80 bar.
BIOFLEX HB – highly dedicated hose designed to transfer chlorine, bromine and other penetrating halogens.

ETH PTFE HOSES

ETH PTFE HOSES

Designed for applications where the temperature of the process fluid entering the hose assembly must be maintained as it passes through the hose or when an option to prevent the medium from solidifying is needed. Widely used for oil, grease, wax, resins, paints, granulates, glue and food substances.
CORROFLON CH, BIOFLEX CH – CH hoses with CORROFLON and BIOFLEX as a base hose where steam is the heating element. Around the base hose there is a spirally wrapped PTFE hose where steam is going through.
CORROFLON ETH, BIOFLEX ETH – ETH hoses with CORROFLON and BIOFLEX as a base hose where heating element is connected to electrical installation. Temperature regulator available on request.
ETH 250 – ETH hoses with smoothbore hose with stainless steel braid reinforcement as a base hose where heating element is connected to electrical installation. DN from DN4 to DN50. Temperature regulator available on request.
