Products / YN Couplings / Grip Ring

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)

Grip Ring – two models: shorter GR-S (DN20-DN350) and longer GR-L (DN25-350). Couplings suitable to be used with metal pipes.
