Fittings for harsh environments LIQUIDLINE and INOXLine push- in fittings are designed for industrial applications requiring the connection and distribution of cooling water, compressed air, gases and liquids. In the search for a solution for especially harsh production environments and higher temperatures, Eisele decided on a high-quality fixed pipe connection that combines all the advantages of the Eisele modular system. industry or automobile manufacturing. At temperatures above 100°C the bursting pressure of hoses declines. The advantage of pipes is that their pressure resistance is virtually constant. fitting geometry ensures high flow rates. Depending on the particular application, different seal materials such as FPM, EPDM or NBR can be used. The advantage of push-in fittings over compression ring fittings is that they allow faster connecting and disconnecting. Eisele offers the option of using pipes instead of hoses especially for the LIQUIDLine fittings made of dezincification-resistant brass and

Standard systems from Eisele are suitable for combination with pipes. Customers can therefore use pipes at temperatures up to 120°C, with the flexibility and convenience of push-in fittings. For stronger thermal loads, Eisele fittings can be equipped with seals that are designed for higher temperatures. Metal pipes can be used wherever a flexible connection is not needed. At high temperatures and unfavourable ambient conditions, a pipe connection is even more economical than a hose connection in the long run. Eisele delivers push-in fittings with diameters from 4 to 20mm, which also makes the concept suitable for the main air supply in machine construction. This type of compressed air connection requires little maintenance and offers a long service life. The optimised

INOXLine fittings made of stainless steel. The application parameters are based on the respective product series. Series 17 and 26 with a seal on the push-in fitting can withstand pressures up to 16 bar, while series 17a and 24 with a double O-ring seal achieve an even better leak- proof seal, making them suitable for higher pressures.

For cooling water applications or especially demanding and corrosive industrial applications, Eisele recommends the combination of LIQUIDLine or INOXLine push-in fittings with highly resistant ProWeld hoses. This combination is suitable for use in extreme conditions and at temperatures up to 100°C, but even this solution approaches its limits in the case of increased abrasion and wear from weld spatter, aggressive cleaning agents, extreme heat, soiling or mechanical stress. Such conditions exist, for example, in foundries, the semiconductor
