Dry Disconnect

Dry Gas Couplings

Dry Gas Couplings


Designed for safe loading and discharge of bobtails or intermediate bulk delivery trucks and transfer to and from rail cars. Quick and easy to connect, can be connected to a tank unit with pressures up to 225 PSI at ambient temperature (70oF). If the pressure is higher you can equip the couplings with a pressure relief valve. The easy to connect pressure relief valve dissipates trapped fluid pressure into the hose coupler without spillage. The primary application for dry gas couplings is in the handling of LPG - Propane and Butane. 

- Safe handling of LPG, Propane and Butane and hazardous gases or fluids

- Reliable and easy to maintain
- Can be coupled to a tank unit with pressure up to 225 PSI
- Minimises the risk of cold burns 
- Minimises spillage and product loss
- Minimises health risks
- Keeps the environment free of hazardous vapors and liquids
- Compatible with existing dry disconnect couplings
- Stainless steel and brass/ gunmetal (produced to US government bronze specification G)
- FKM (FPM) seals
- Female NPT, female ACME and ASA flanges
- Working pressure: 360 PSI at ambient temperature (70oF)
- Composite (Polyeten PE-HD 300) plug to provide good protection in harsh environments
