Main image. Main image. Main image. Main image.


Clamped-on KAN-therm Inox Sprinkler connectors are made of stainless steel – material No. 1.4404 to EN 10088. Standard connectors are provided with an O-ring of EPDM rubber. O-rings of the DN20 - 50 connectors feature a function of signalisation of not assembled (clamped) LBP connections (Leak Before Press) – „not clamped – not leak-proof”. Diameter range: DN20 - DN100.

Connectors are provided with pressed on tips with an O-ring or with tips pressed on and threaded with a female of male thread to PN-EN10226-1:

  • knees/bends and tees, connectors

  • connectors with GZ and GW threads and screw joints

  • approaches for receivers

  • special fittings


Sealings (O-rings)

Standard „Press“ fittings in the KAN-therm Inox Sprinkler System are provided with EPDM rubber O-rings satisfying the PN-EN 681-1 standard.

Working parameters and the scope of application of these seals are given below:

Material EPDM LBP (DN20-DN50) EPDM (DN76,1-DN108)
Colour black black
Coating without silicone – PTFE-based without silicone – PTFE-based
Temperature minimum/maximum -35°C do + 135°C od - 20°C do +85°C
Short-term working temp. 150°C  120°C
Max. working pressure 16 bar 16 bar
Scope of applicability without silicone – PTFE-based without silicone – PTFE-based

All the fittings of KAN-therm Inox System within 15-108 mm dimensions contain LBP function (unsealed connections alert - LBP-Leak Before Press).

Within 15-54 mm dimensions the function is realized by a specially designed O-rings. With a special grooves LBP O-rings provide optimal control over connections during the pressure test. Unsealed connections are leaky and therefore easy to locate.


Within 76,1 - 108 mm dimensions the LBP function is realized by an appropriate shape of fitting (pipe connector ovalisation).
