Common Applications

Pressure systems (potable water, mining, industrial plants)
Drainage and sewer lines
Fire protection systems
Temporary or emergency repairs
Vibration and movement zones (e.g., pump stations)
Joining dissimilar materials (PVC to HDPE, steel to ductile iron)

Installation Notes

No pipe end preparation required – no welding, threading, or beveling.
Only a torque wrench needed to install. Torque values indicated on each coupling.
Open-style couplings (Straub Open Flex, Orbit Open Flex) are ideal for retrofit and repair work.
Save time, space, and money compared to traditional flanged or welded connections.
