DryLink Dry Disconnect Couplings

DryLink is the market leader of the dry break range of couplings and exclusive to Action Sealtite. It’s unique patented design means that the flow is controlled by one single handle, which is attached only to the coupler. The handle operates the adaptor valve as well as the coupler making it very quick to secure and easy to use. More importantly, it is the only true non-spill coupling available in the world. The most you can expect to find on the plates after disconnection is a few tiny pinhead droplets of liquid. 

“Independent, third party testing by Factory Mutual Research has verified that the 2” (DN 50) size Dry Link hose coupling assembly had only 1 to 2 drops of total cumulative leakage after a total of 10 connect/disconnect cycles. No other product comes close!”

Where can you use DryLink?

Drylink can be used in any application where a dry disconnection is required but is most commonly used in industries where fluids are hazardous, toxic, corrosive or flammable or if the liquid is of a considerably high value. Typical industries include chemical, pharmaceutical, cosmetics, printing, paints, soap, food and drink, hygienic, nuclear and microelectronics. Dry Link can be used on IBCs.

Why use DryLink?

It is the most superior product available on the market today and this is due to the unique design:

  • It is a ‘true’ dry disconnect – no drips – no spills!
  • Servicing of the fittings is easy. All that is required is a pin pusher, a hammer and an allen key. Servicing can be done on site and in situ, saving potentially thousands in downtime for repair and or maintenance. DryLink spares are also available direct from us
  • Diversity – the range is almost infinite, with many options for materials and an option for polishing, your Dry Link coupling really can be made bespoke to your application
  • Safety – when connected and the valves are open it cannot be disconnected and when disconnected the valves cannot be opened. In either scenario, hazardous or valuable fluids cannot be accidentally lost
  • Double butterfly valve, flow is not comprised – saves time and increases productivity
  • Easy and quick to operate – increases productivity and speeds up work flow

What are Keyed Couplings?

Dry Link “keyed” couplings are used in batch process plants and manifolds for preventing accidental cross-contamination of chemicals. 

Dry Link is a premium product for special applications. 

If you can accept a very minimal ‘smear’ type of fluid loss, and your budget would be suited to another type of dry break, you could consider CleanBreakBanjo Dry-MateParker 71 Series or Maxi-Dry, which are also dry disconnects.
