1'' Dry-Shut™

Dry-Shut™ Precision Spill Control Couplings

The CPP® Dry-Shut™ range is a precision moulded minimum spill coupling system designed for safe, clean and reliable low pressure liquid transfer applications. Engineered for industrial, chemical and fluid handling environments, the Dry-Shut™ system helps minimise fluid loss and air inclusion during connection and disconnection.

Using a simple ISO 7241-1 Series B (ISO-B) interchangeable design, the couplings automatically close internal poppets when disconnected, shutting off liquid flow with no levers or external switches required. This makes the system fast to operate, easy to handle and ideal for repeat connection applications where cleanliness and reduced spillage are important.

Manufactured by CPP® in glass filled polypropylene (GFPP), the Dry-Shut™ range combines lightweight corrosion resistance with excellent chemical compatibility. Precision moulded internal components and Viton® sealing elements provide reliable sealing performance across a wide range of industrial liquids and chemicals.
