Dry-Disconnect Couplings: Precision Containment for Critical Transfers
Dry Link dry-disconnect couplings are a true drip-free solution, engineered to protect your team and your product during critical transfers. JHFOSTER provides these components to operators who can’t afford leaks, spills or contamination when handling hazardous, high-viscosity fluids and ultra-clean sanitary media.
Engineered for Safety, Built for Performance
Core advantages of Dry Link dry-disconnect couplings include:
- No Drips, No Spills: Automatic shutoff ensures components seal before separation, eliminating costly cleanups and fluid loss.
- Better Flow: A smooth-bore, butterfly-style shutoff provides a direct flow path with minimal turbulence and low pressure drop, even when transferring high-viscosity media.
- Lightweight and Compact: Our designs are up to 50% lighter and more maneuverable in tight spaces than standard couplings.
- Safety Interlocks: Built in interlocks prevent accidental opening, supporting strict U.S. Environmental Protection Agency (EPA) and work safety compliance.
Versatile Applications Across Critical Industries
Dry Link dry-disconnect couplings are trusted wherever precision and containment matter, including:
Chemical and Petroleum Industries: Safe transfer of corrosive and aggressive fluids using Hastelloy C or Alloy 20 wetted parts.
Food, Beverage and Pharmaceutical Production: In sanitary applications, mirror-finish internals (20 RA) eliminate bacterial growth for ultra-clean transfers.
Semiconductor and Nuclear: High-precision containment for sensitive or hazardous environments.
Bulk Transfer: Securely containing hoses to tanks, pipes and manifolds for mobile transfers.
Dry-Disconnect Coupling Product Selection
Standard & Sanitary Couplings (316 Stainless Steel)
Ideal for general industrial and ultra-clean pharmaceutical and food applications.
| Size (DN) | Body Material | Features |
| ½” – ¾” – 1″ – 1½” (DN 15-40) | 316 Stainless Steel | Standard swivel for hose alignment; available in Threaded, Flanged, or Triclover ends |

Specialty Material Couplings (Corrosion Resistance)
Engineered for aggressive fluids that require advanced metallurgical compatibility.
| Material | Available Sizes | Typical Use Case |
| Alloy 20 | 2″, 3″, 4″ | Aggressive chemicals and oxidizing acids |
| Hastelloy C | 1″, 1½”, 2″ | Highly corrosive environments; wetted parts built for long-term reliability |
Keyed Couplings (Prevention of Cross Contamination)
Designed for batch processing and manifold systems to ensure only matched pairs connect.
| Feature | Description |
| Error-Proofing | Custom-machined mechanical keys prevent accidental connection of different media |
| Field-Replaceable | Larger sizes (2″-4″) use field-replaceable keys for unique left/right combinations |
| Set Codes | Available in a wide variety of set codes (A-U) to manage complex manifold systems |
Technical Specifications and Customization
High-performance couplings provide reliability in demanding applications. Operational capabilities include:
- Maximum Working Pressure: Up to 210 psi (14.3 bar) for smaller sizes.
- Temperature Range: -20°F to +230°F, depending on seal material (Viton, EPDM, PTFE or FFKM).
- Vacuum: Tested to 28” Hg vacuum in all positions without leakage.
