Repair Clamp Hinge

Products / YN Couplings / Repair Clamp Hinge

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)

Repair Clamp Hinge – two models: shorter RCH-S (DN20-DN500) and longer RCH-L (DN25-500). The couplings are suitable to be used with all pipe materials with new mountings as well as during repair works.
