Stainless Steel Heavy Duty Flexible Coupling, Model 97HP
The model 97HP stainless steel flexible coupling is designed for high pressure applications including reverse osmosis and desalination systems. To adapt the special environment, the housing materials are made from high strength and corrosion resistance material of duplex CD3MN (2205) and super duplex steel CE8MN, CE3ME (2507). The bolts are made from 316L stainless steel and the heavy duty nuts are made of silicon bronze to help prevent galling during repetitive use.
- Size: 3/4"to 12" (DN20 to DN300)
- Rated working pressure: 1200 psi (83 bar)
