LIQUIDLINE cooling water connectors
LIQUIDLINE cooling water connectors
- Compressed-air tubes made of PTFE (Teflon) and FEP must have an undamaged outside diameter. Use specific Eisele tube cutters for precise cutting.
- Ensure tubes are pressed to the bottom of plug connectors for proper tightness.
- Designed for high tightness applications up to 348 psi (24 bar), with some capable of up to 1450 psi (100 bar).
- Features include release sleeves and dual seals.
- Available in straight and angled forms, with specifications for various tube sizes and pressures.
- Made from brass, resistant to dezincification, with FPM seals.
- Temperature range: -4 to 248 °F (-20 to +120 °C).
- Whitworth pipe thread DIN ISO 228, with chambered O-ring and FPM seals.
- Suitable for pressures up to 348 psi, with potential for higher pressures depending on tube specifications.
- Swiveling and lockable options available, not designed for steady tube motion.
- Made from brass with FPM seals, suitable for a wide temperature range.
- Includes T-connectors, bulkhead connectors, and Y-plugs, all made from brass with FPM seals.
- Designed for various tube sizes and pressures, with specific part numbers and dimensions provided.
- Designed for high retention force and dynamic applications.
- Features include full tube passage, intuitive assembly, and the ability to disassemble without tube damage.
- Suitable for a temperature range of -4 to 248 °F and pressures up to 232 psi, depending on the tube used.
- Ensure proper assembly and tightening of connectors to prevent leaks.
- Consult specific part numbers and dimensions for compatibility with your application.
1. Polyethylene (PE): 14 to 104°F (-10 to +40°C)
2. Polyamide (PA): -76 to 212°F (-60 to +100°C)
3. Polyurethane (PU): -31 to 158°F (-35 to +70°C)
4. ProWeld (PUR): -31 to 194°F (-35 to +90°C)
5. Teflon (PTFE) / FEP: -31 to 248°F (-35 to +120°C)
Various tube sizes are specified with their respective minimum bending radius (R min.) and maximum pressure (p max.) in psi and bar. For example, a tube with an outside diameter of 4 mm has a maximum pressure of 290 psi (20 bar) for PE and 435 psi (30 bar) for PA.
- Compressed-air tubes should not be exposed to tensile loading.
- For PTFE and FEP tubes, ensure the outside diameter is free of damage and use specific Eisele tube cutters for right-angle cuts.
- During assembly, tubes must be pressed to the bottom of plug connectors for proper sealing.
- Threaded connectors and plug connectors are available with various specifications, including temperature and pressure ranges.
- Materials used include stainless steel AISI 316L with FPM seals.
- Connectors are suitable for extreme environments with a working pressure range of -14 to 232 psi (-0.95 to 16 bar).
- For screw joints, push the tube into the joint up to the limit stop and tighten the union nut by hand or with a wrench.
- Suitable for cooling water circuits, connections with high retention capacity, and systems with high dynamics.
Eisele offers tailored connection solutions that include a combination of different connection and screw joint series, special threaded connections, and adaptations for other systems. They provide various sealing materials and integrated valve technology, along with color coding and pre-assembled components. Multiple couplings are also available.
Eisele provides a versatile range of plastic tubes suitable for various applications, including standard compressed-air tubes and those for special applications. Tubes are available in different materials such as PU, PA, PTFE, FEP, and PFA, each with specific temperature and pressure resistance characteristics. Tubes can be color-coded and labeled for easy identification.
- PU (Polyurethane): Flexible, resistant to buckling, suitable for compressed air and water, and compliant with various standards.
- PA (Polyamide): Suitable for vacuum and automotive industry, resistant to fuel, and compliant with DIN 73378.
- PTFE (Teflon): Resistant to UV and solvents, suitable for high temperatures, and FDA compliant.
- FEP (Fluorinated Ethylene Propylene): Very flexible, resistant to UV and microbes, and FDA compliant.
- PFA (Perfluoro Alkoxyalkane): Resistant to UV, hydrolysis, and weld spatter, and FDA compliant.
Eisele provides tube cutters for compressed-air tubes with outer diameters of up to 14 mm and 22 mm, made from durable materials like plastic, steel, and zinc die-casting.

Quality solutions - Made by EISELE Material properties - Brass, dezincification free What is dezincification? Dezincification is a long-known process that can lead to corrosion damage on cooling water fittings. In rare cases it is observed on brass components that are in constant contact with water. The colour of the corroded area changes to reddish copper, indicating that it no longer has any inherent strength. Explained simply, the main alloy components of the brass dissolve: copper and zinc are oxidised into water-soluble salts. The zinc is carried away by the cooling water, while the copper...
