Hose barbs with external threads are screw-in barb connectors made from plastics such as HDPE, PA, POM, PP, PVDF, and PTFE.

Screw-in barb connectors/hose barbs with external threads from these plastics, particularly HDPE, PA, POM, PP, PVDF, and PTFE, are exemplified by screw-in barb connectors made of PA 6 (Polyamide 6). Generally, for these:

  • The connectors are adjusted for a temperature range from -10 °C to +70 °C.
  • They ensure a maximum working pressure of 8 bar at +20 °C.
  • They are highly impact-resistant/tough according to DIN 53453.

Screw-in barb connectors made of POM (Polyoxymethylene/Delrin®):

Screw-in barb connectors made of POM are characterized by high mechanical hardness and strength.
They feature good sliding friction coefficient. Their dimensional stability is noteworthy. POM is considered physiologically safe and therefore food-grade. Its working temperature ranges from -40 °C to +105 °C, temporarily up to +140 °C.

Hose barbs made of PP (Polypropylene/Hostalen® PP):

  • These hose barbs are distinguished by the highest mechanical strength.
  • Their chemical resistance and thermal resistance are very good.
  • The material is hydrolysis-resistant and has excellent dielectric properties.
  • However, the material is not suitable for very low temperatures as it becomes brittle.
  • PP is food-safe and complies with drinking water regulations according to KTW.
  • Additionally, PP is FDA and BfR compliant.
  • Hostalen® PP ensures resistance to lubricants, gasoline, aliphatic hydrocarbons, alcohols, ketones, as well as organic and mineral/inorganic acids, hydrogen peroxide, and alkali solutions.

Screw-in barb connectors made of PVDF (Polyvinylidene fluoride/Solef®/Kynar®):

  • PVDF is a fluoroplastic and a high-performance material.
  • It has excellent chemical and temperature resistance.
  • PVDF is hydrolysis-resistant and has the highest thermal shape stability.
  • It possesses excellent electrical insulating properties and is completely radiation-resistant, suitable for nuclear technology.
  • The fluoroplastic PVDF is BfR and FDA compliant.
  • As a fluoroplastic, PVDF resists lubricants, gasoline, other aliphatic hydrocarbons, organic and mineral acids, alkali solutions, and amines.
  • PVDF is less resistant to xylene, benzene, other aliphatic hydrocarbons, esters, ketones, oxidizing acids like nitric acid, and UV radiation.

Hose barbs made of PTFE (Polytetrafluoroethylene/THOMAFLON):

  • PTFE is a fluoroplastic with the highest chemical resistance, except against fluorine and free alkali metals.
  • Its temperature resistance is remarkable, from -260 °C to +260 °C, temporarily up to +280 °C.
  • Its Shore hardness is D 55° to D 59° as per DIN 53505.
  • Its electrical insulating properties are well-known in high-voltage and HFN technology.
  • Fluoroplastic PTFE shows absolute resistance to lubricants, gasoline, other aliphatic hydrocarbons, benzene, xylene, and other aromatic hydrocarbons, phenols, halogenated solvents, free halogens, esters, ketones, alkali solutions, ammonia, and amines, as well as organic and inorganic/mineral acids, ozone, and other oxidizing agents, but also hydrogen peroxide, hot water, steam, and UV radiation.
  • PTFE is unstable against free alkali metals and fluorine; the material decomposes.

Screw-in barb connectors made of HDPE (High-Density Polyethylene):

  • The HDPE material is characterized by the best weather and aging resistance.
  • Its surface is non-adhesive.
  • It is particularly resistant to impacts, even at low temperatures.
  • It is especially resistant to acids, bases, oils, and gasoline.
  • The material is considered temperature-resistant from -50 °C to +90 °C.
  • The material is resistant to lubricants, oils, and fats, gasoline and aliphatic hydrocarbons, alcohols, esters, ketones, organic acids, and inorganic/mineral acids, as well as in hot water, alkali solutions, ammonia, and amines.
