• Designed for clean connection/disconnection without fluid loss
• Supports a variety of seal materials (Buna-N,Neoprene,EPDM,FKM)
• Wide range of thread configurations and sizes
• Compatible with steel, brass, and stainless steel variants
Material Compatibility & Seal Options
CB-SP-1F is available in multiple material constructions (e.g., carbon steel, brass, 303/316 stainless steel) and supports several industry-grade seal materials:
| Seal Material | Max Temperature |
| Buna-N | -40°C to +121°C |
| Neoprene | -54°C to +100°C |
| EPDM | -54°C to +149°C |
| FKM | -29°C to +204°C |
This flexibility allows the CB-SP-1F to be adapted to different fluids and environmental conditions, whether you're dealing with mineral oils, synthetic compounds, or compressed air.
