EISELE LIQUIDLINE

Screw-in and push-in fittings of brass, aluminum and stainless steel

Connectors for coolant applications

The Eisele LIQUIDLINE offers the most extensive line of screw-in and push-in fittings for coolant applications on the market. High-quality craftsmanship and low production tolerances set the Eisele LIQUIDLINE – quality made in Germany – apart from the coolant fittings of other manufacturers. The Eisele LIQUIDLINE is designed for long-term operation with no leaks or corrosion even under harsh ambient conditions.

Push-in coolant fittings and diverse other connections are supplemented by compatible tubes. Especially for high stress conditions such as in welding applications, flame-retardant and robust ProWeld tubes made of polyether-polyurethane are used. Accessories for the product line include colour-coded sleeves to eliminate the risk of incorrect connection of coolant fittings, a pipe/tube adapter for the transition from pipes to tubes and special parts for the transition from oval copper cooling coils to tubes.

 Properties

The coolant connections are made of dezincification-resistant brass, seawater-proof aluminum or stainless steel. FKM (Viton) is used for the seal material. LIQUIDLINE push-in coolant fittings are resistant to high temperatures, aggressive aqueous media and many other substances.

Types

To provide connections for diverse applications, Eisele also offers Series 4500 and 4600 with push-in and screw-in coolant fittings made of highly resistant stainless steel. Series 5500 with screw-in fittings of seawater-resistant aluminum is designed for use in combination with aluminum heat sinks. We offer special swept screw-in elbows of brass or stainless steel for extra high flow rates.
