About Hose fittings and swivel nuts

Hose sleeves and coupling nuts together form a detachable hose connection. The sleeve sits inside the hose while the nut pulls it against the mating thread. The range covers female threads from G 1/8 to G 1 and is rated from 25 to 60 bar working pressure depending on material.

What matters when choosing

• Thread: female threads from G 1/8 to G 1, plus left-hand threads in G 1/4, G 3/8 and G 1/2 for lines where a mix-up has to be ruled out.
• Sleeve and hose size: the sleeve and hose figures have to match. One coupling nut often serves several sleeve sizes, for example I.D. 4, 6 and 9.
• Material: brass CW614N for general use, electroplated nickel-plated brass CW614N where corrosion is a factor, stainless steel 1.4571 for aggressive media.
• Working pressure: the range spans 25 to 60 bar. The figure given applies to the part itself, while the hose sets a further limit on the joint.
• Spanner size: SW and the lengths L1 and L2 are stated and decide whether the joint can still be reached with a spanner in a confined position.

Typical applications

• Connecting compressed air and water hose to pipework and fittings.
• Workshop installations where hoses are disconnected regularly for cleaning or replacement.
• Oil and steam lines in plant engineering, provided the hose material is approved for it.
• Test rigs and laboratory setups, using the stainless steel 1.4571 version.
• Lines with left-hand thread where connections must not be interchanged.

Materials available are brass CW614N, electroplated nickel-plated brass CW614N and stainless steel 1.4571, with a maximum operating temperature of 150 °C. Production comes from Germany, Greece, Italy, Turkey and India.
