Nominal Pressure (PN)

The Pressures specified are in accordance to DIN 2401 part 1 draft. The pressure has a safety factor of 4 times according to DIN 3859 standards.

Pressure Range

  • LL Series: Up to 100 Bar
  • L Series: Up to 500 Bar
  • S Series: Up to800 Bar

Compression Fitting Temperature ratings vary in accordance to the body material as per below:

Body Material Temperature Rating

  • Stainless Steel:-60oC to 400oC (DIN 17440)
  • Steel:-40oC to 120oC (DIN 3859)
  • Brass:-60oC to 175oC

When combing seal material,then temperature ratings of seal may become the limiting factor on the fitting's temperature rating.Kindly refer to the temperature rating below:

Elastomer's Temperature Rating

  • NBR:-35oC to 100oC (Default Option)
  • Viton:-25oC to 200oC
  • PTFE:-60oCCto 240oC

Presure Reduction in temperature

There are reductios in the nominal pressure(PN) caused by the temperature of the fluid medium or surroundings.
