Emergency Seal for Elbow Joint Leaks
The Elbow Joint Emergency Repair Clamp is for emergency elbow leaks. Elbow joints experience high stress from water turning. The rubber rings at elbow joints age faster than on straight pipes. When an elbow joint leaks, it is often severe. Our clamp gives you an emergency seal without removing the elbow.
The housing matches the elbow bend radius. It covers the elbow body and both socket ends. The gasket follows the curved path of the elbow. It seals the inner curve and outer curve equally. Multiple bolts compress the gasket evenly around the whole elbow. The clamp does not add much size. It works in tight valve pits and small chambers. The clamp creates a new seal independent of the old rubber ring.
We have many patents for elbow repair products. We have experience with both standard and custom angles. We hold ISO 9001 certification. Our quality team checks every clamp for fit and pressure resistance. We can custom-make based on your elbow angle and size.

Used in a Chemical Plant Fire System
A chemical plant had a DN150 elbow leak on their fire water line. The elbow was in a tight space. The line could not be shut down. The plant used our Elbow Joint Emergency Repair Clamp. The curved housing fit around the elbow. The team installed it in the confined space. The leak stopped and the fire system stayed operational.
We offer a 10-year warranty. The housing is QT450 ductile iron with epoxy coating. The gasket is EPDM rubber with chemical resistance. Sizes cover DN40 to DN300. Standard 90° elbows are available. Other angles are custom-made.
