About Reducing adapters

Reducers bring two different pipe threads together and save an extra adapter in the line. The group covers threads from G 1/8 to G 1 1/2, each as male or female. The parts are rated PN 250 to 630 bar.

What matters when choosing

• Thread 1 and thread 2: the pairing sets which size changes into which, for instance G 1/2 male to G 3/8 female.
• Pressure rating: PN runs from 250 to 630 bar, with the smaller thread sizes reaching the higher ratings. For the line as a whole the lowest rating among the fitted parts counts.
• Material: galvanised steel to DIN 2353 for standard duty, stainless steel 1.4571 where corrosion or demanding media are involved.
• Version: the soft sealing heavy version with an FKM seal makes sense where vibration or frequent disassembly would strain a metal to metal joint.

Typical applications

• Adapting hydraulic power units to existing connection threads
• Pipework built with compression fittings
• Machine tools and presses with high pressure circuits
• Retrofitting measuring and test ports
• Maintenance work where pump and line carry different threads

The parts follow DIN 2353 and are available in galvanised steel and in stainless steel 1.4571, soft sealing versions with FKM. Manufacturing takes place in Italy, Germany and Poland.
