Can TW couplings be used for food substances?
We do not recommend using TW couplings for foodstuffs. Due to their nature and construction, TW couplings do not meet the standards for couplings intended for food substances.
Do you always need to use GSD profiled seals?
No, TWF or TWO profiled seals can be used instead of GSD coupling seals, but we recommend checking the tightness of the connection each time.
What temperatures can TW couplings operate at?
According to DIN 28450 standard, TW couplings can operate at temperatures up to +65°C. If they need to be used at higher temperatures, it is necessary to consult Tubes International's Technical Department.
What is the service life of silicone automotive hoses/connectors?
The service life is very long, often longer than the lifespan of the car on the road. Car manufacturers appreciate silicone-based materials for their durability, mechanical properties and overall performance.
Why are most automotive hoses and connectors made of silicone?
Silicone hoses and connectors operate at much higher pressures and temperatures (up to +300° for fibreglass reinforcement) than other rubbers, while retaining good flexibility.
Where are automotive hoses and connectors used?
Their basic applications include systems related to a powertrain, such as fuel system, cooling, intake, lubrication, and exhaust systems, but also braking, air conditioning, ventilation, and heating systems.
Does a rubber steam hose need to be drained after use?
Rubber steam hoses should be drained after each use. Condensate remaining in the hose may be absorbed by the inner layer of the hose wall. When the hose is reheated, the condensate transforms into steam and expands damaging the inner layer ('popcorning’ effect). If the condensate comes into contact with the steel braid, it can [...]
Can rubber steam hoses be used in an oily environment?
Only hoses specifically designed for oily environments can be used in such conditions. It must be clearly indicated in the product specification that the outer layer of the hose is oil resistant. If the hose is manufactured according to EN ISO 6134 standard, make sure that the hose class is specified as 'B'. Class 'A' [...]
Can steam hoses be wound on hose reels?
Steam hoses can be used on hose reels provided that the appropriate operating procedures are followed. Before this set is used, the hose must be completely unwound. It is also important to check the condition of the hose periodically and make sure that the safety clamps are tight. During operation, the drum may become very [...]
What type of fittings are used for steam and how are they mounted?
For steam hoses, use fittings designed and intended for steam. EN 14423 standard is the most popular. There are special steam safety clamps made to the same standard, intended for this type of fittings. The fittings permanently crimped with ferrules must not be used for rubber steam hoses. This type of mounting does not allow [...]
