■ Main Parts and Materials
· Cylindrical Middle Ring: This central ring connects the two pipe ends.
· Follower Rings: There are two follower rings, one on each side of the middle ring. They help secure the pipes.
· Resilient Gaskets: These special Dresser compound gaskets absorb vibration and movement while maintaining a seal.
· Steel Track-Head Bolts: These bolts hold the coupling together.

Coplue Dresser Installation Process:
Place the coupling around the pipe ends.
Insert the gaskets between the follower rings and the pipe.
Tighten the bolts to compress the gaskets and create a secure connection.
The resilient gaskets allow for movement while maintaining a leak-free joint.
Flexibility: Dresser couplings accommodate pipe movement due to temperature changes or ground settling.
Quick Installation: They’re easy to install, saving time and labor.
Vibration Absorption: The gaskets absorb harsh vibrations, reducing stress on the pipes.
Remember, Dresser couplings are a reliable choice when you need a flexible and efficient pipe connection!
