  • We are building a Launch Pad to interface with a rocket from a rocket lab. We must install the same Dry Break that is currently used which is a: Stucchi 6025 1" BSPP, flat face drybreak. We would prefer SAE not BHPP.
  • We are currently using flat face couplings on a hydraulic breaker and after a short amount of time, the two halves become locked together and need to be replaced. Is there a different product better suited for our application?
  • We are currently using poppet style couplers on our snow removal equipment and often experience water freezing in the couplers when left out all night and oil spillage on disconnection. Do you have a better option for a small fleet of plow trucks?
