Epsilon™ Dry Disconnect Couplings
Featuring an innovative double ball-valve system, Epsilon™ Dry Disconnect Couplings deliver the lowest product loss in the industry. A tactical balance of an unrestricted flow path and double shutoff reliability makes Epsilon™ the safest and most efficient coupling system in the world.
Features & Benefits
- Lowest fluid loss, driven by the innovative unique double ball-valve system, ensures the lowest product loss in the industry.
- Unparalleled safety with multiple interlocks that eliminate unintentional disconnects and chemical releases that could threaten worker safety and the environment.
- Full flow with unrestricted flow path. No turbulence!
- Optimal defense against cross-contamination with optional keyed couplings that mechanically lock out and isolate transfer lines.
- Engineered for easy operation and maintenance with no special tools needed for seal replacements.
- 316 Stainless or Hastelloy® Construction for critical, aggressive, corrosive fluids.
- 1", 2" and 3" sizes
- Pressures up to 435 psi (30 bar)

Options
- Ultra Low Spill Face Seal
- This seal reduces the amount of spillage at disconnect to .2 cc. This seal is not pressure assisted and should only be used for applications lower than 100 psi.
- Cavity Filled
- Designed to reduce the possibility of contamination by entrapment of process fluid in the void normally found behind the ball and the valve body. Ideal for applications where cross-contamination and cleanliness is a concern. Back side of the valve balls are bored for efficient cleaning.
- Keyed Couplings
- For extremely critical operations, Epsilon offers the unique keyed interface which locks out and isolates transfer lines, preventing cross-contamination.
Dual Ball Race (Optional)
- Radial swivel seal
- Replaces dynamic face seal
- Lower leak rate
- Lower seal mortality rate caused by over-compressing seal to install bearings
- Dual ball races with hardened stainless bearings
- Replaces PTFE sleeve bearing that may become overloaded and allow greater axial misalignment causing the dynamic face seal to leak
- Provides additional support for applications with long hose drops or high load requirements
- Spring energized dust seal
- Transportation Coupling System (TCS)
- Specially designed for railcar, truck, isotainer or tote equipment used in transporting chemicals safely. Contact us for more information.
