What is a Dresser Coupling?
A Dresser coupling is a mechanical fitting designed to connect two pipe sections securely without the need for welding or threading. These couplings typically consist of a metal sleeve with rubber gaskets, which ensure a leak-proof connection. Originally designed for cast iron pipes, they are now widely used with various materials, including steel, PVC, and ductile iron, making them versatile for different applications.
Components of a Dresser Coupling
Dresser couplings generally consist of three main components:
- Metal Sleeve: The primary body that encases the pipes.
- Rubber Gaskets: These create a seal between the pipes, preventing leaks.
- Bolts and Nuts: Used to secure the coupling to the pipes, ensuring a tight fit.
Each component plays a crucial role in the coupling’s overall functionality, providing a durable and flexible connection.
Types of Dresser Couplings
Dresser Style 38
Dresser Style 38 couplings are the most commonly used type. They are designed for standard applications and provide a reliable connection for typical piping needs. Their ease of installation makes them a popular choice among professionals.
Dresser Style 65
These couplings are engineered to accommodate axial movement, making them ideal for larger pipes. Dresser Style 65 is particularly useful in environments where thermal expansion and contraction occur.
Dresser Style 90
