About Elbows

Elbows turn a line through 90 degrees where there is no room for a pipe bend or where a branch has to leave sideways. The group covers threads from G 1/8 to G 1 and is rated for operating pressures up to 150 bar depending on version. That makes it the part for tying valves, gauges and equipment ports in close to the machine.

What matters when choosing

• The thread pairing decides the part. Female/female, female/male and male/male versions are available, with thread 1 running from G 1/8 IT to G 1 IT or Rp 1/8 IT to Rp 1 IT.
• Parallel female threads carry the G or Rp designation and tapered male threads the R designation. Rp with R is the pairing normally used in pipework, and thread 2 offers R 1/8 ET to R 1 ET for it.
• Where thread 1 and thread 2 differ in size the elbow also acts as a reducer and saves a separate fitting.
• Maximum operating pressure ranges from 16 to 150 bar. The figure varies by version and should be checked against the system pressure.
• Maximum operating temperature falls between 120 and 175 °C depending on the article and sets the limit for hot media.

Typical applications

• Direction changes in compressed air distribution where the branch sits tight to a wall or frame
• Connection of pressure gauges and measuring points taken off the side of a line
• Ports on FRL assemblies and valves with limited installation space
• Pipe routing in plant construction where one thread size changes to another
• Medium pressure hydraulic circuits, which the versions rated to 150 bar cover

Documented figures are maximum operating pressures to 150 bar and operating temperatures to 175 °C, with production in Italy and China. The group holds 91 articles with female and male threads from G 1/8 to G 1.
