2. Coupling Body Material

• Ordinary service environment: Carbon steel
• Harsh, rust-prone environment: Stainless steel or brass
• Compressed air as fluid: Carbon steel with chrome/nickel plating, brass or stainless steel are all acceptable
• Steam as fluid: Stainless steel is required
• Corrosive fluid: 316 or 316L stainless steel

3. Seal Material

• Hydraulic oil or water-glycol fluid: Nitrile rubber (NBR) for ambient temperature; Fluororubber (FKM) for high temperature
• Corrosive fluid: Fluororubber (FKM)
• Water as fluid: EPDM or nitrile rubber (NBR)
• High-temperature fluid: Fluororubber or silicone; Perfluororubber for operating temperature ranging from 200℃ to 300℃
• Low-temperature fluid: Hydrogenated nitrile rubber (HNBR)

4. Check Valve Configuration

• Both male and female ends need fluid shutoff after disconnection: Check valves installed on both ends
• Only one end needs fluid shutoff after disconnection: Install check valve on that single end (usually the female end)
• No fluid shutoff required on either end after disconnection: Straight-through type without check valves
