Products / YN Couplings / Fire Protection Cover

YN pipe couplings (straub-type coupling)

  • Easily and quickly installed without special tools
  • Lightweight, space saving structure

Material: Stainless steel SUS 304/316/316L

Gasket: EPDM -30°C – +100°C (water, waste water, air and some chemical products) or NBR -20 °C – +80 °C (oil, gases, gasoline and other hydrocarbons)
