About Hydraulic couplings

Hydraulic couplings disconnect and reconnect fluid lines without tools. Versions that shut off on both sides hold the medium in each half of the line, so very little oil is lost when uncoupling. Maximum operating pressure runs from 10 to 400 bar depending on size, with connections from G 1/8 IT to G 1 IT.

What matters when choosing

• Connection: G 1/8 IT through G 1 IT, which together with the nominal bore sets the flow that can be reached.
• Operating pressure: the maximum lies between 10 and 400 bar. Smaller bores cover the higher pressures, larger bores correspondingly less.
• Housing material: plain brass, nickel plated brass, steel, stainless steel 1.4305 or white POM (Delrin), chosen by medium, corrosion load and weight.
• Sealant: NBR for mineral oil and normal temperatures, FKM where medium temperature reaches up to 200 °C.
• Overall length: allow 29.5 to 96 mm when the coupling sits inside a power unit or behind a cover.

Typical applications

• Machine and plant construction with hydraulic lines that are opened regularly
• Manufacturing industry, for example on clamping fixtures and tool change points
• Chemical and pharmaceutical plant using the stainless steel 1.4305 versions
• Automotive applications with changing test and filling points
• Food technology where lines are disconnected for cleaning

The couplings that shut off on both sides for liquid media follow ISO 7241 series B and are sealed with NBR or FKM. Production takes place in Germany, Sweden and Spain.
