SYSTEM TECHNICAL SPECIFICATIONS

Joint type: O-ring resistant to hot water, ageing and the additives commonly used in drinking water. There are three kind of O-rings depending on its application (NBR available also under request).

Fitting material: Stainless steel nº 1.4404 (AISI 316L). Characteristics:

  • Hygienic, as demonstrated in many food and pharmaceutical industry applications.
  • Minimum load loss, resulting in faster fluid flows.
  • Excellent decorative finish avoiding need for additional painting or external protection costs.
  • Less heat conduction than other materials.
  • The use of molybdenum results in good performance in chlorinated environments.
  • Good resistance to oxidation and good mechanical and deformation resistance at high temperatures.
  • Environmentally friendly.

Joint type: Cold joint ideal for joining thinwall stainless steel pipes.

Working pressure: Max 16 bar

Working temperature:

  • With EPDM O-ring (black) –20 ºC to +110 ºC
  • With FKM O-ring (green) –20 ºC to +200 ºC
  • With FKM O-ring (red) –10ºC to +200 ºC

Wall-thickness of the fitting:

  • 1.5 mm for diameters 15, 18, 22, 28, 35, 42, 54
  • 2 mm for diameters 76.1, 88.9, 108, 114.3, 139.7, 168.3
  • 2.6 mm for diameters 139.7, 168.3
