4-inch Rubber Coupling 4-inch Flexible Cuff Rubber Coupler Rubber Pipe Joint

Reducing a 4-inch dust port on your machinery has never been easier! With our 4-inch to 2-1/2 inch hose reducer fitting and rubber coupler, you can connect a 2-1/2 inch hose directly to a 4” port on machines like band saws, table saws, large planers, and more. This convenient combo pack is designed to accept most standard-size 4-inch dust collection fittings such as Y’s, T’s, Elbows, Blast gates, Dust ports, and other standard-size 4-inch dust collection fittings.

Most wet/dry vacuum hoses will plug directly into the smaller end of this fitting making it a super value for most professional and our weekend warrior-type woodworkers. There are some vacuum units that use different size hoses and hose adaptors so please be sure to measure your hose and machine ports before making a purchasing decision.

Two stainless steel hose clamps help provide a tight seal on the 4-inch end and keep the reducer from falling out. These clamps fit neatly into the slots around the coupler so there is no slipping when tightened. No more busting your knuckles. Each clamp is equipped with a blue turn-key mechanism to make tightening and loosening the clamp super easy.

The rigid rubber coupler seals tightly around the reducer for excellent airflow. Easy to install and easy to remove. As with most all other dust collection fittings, it’s always a good idea to have extra on hand when you need it. It’s always better to have it and not need it than it is to need it and not have it.

Made from high-quality Rubber for extended periods of use, the reducer fitting will withstand the constant friction and debris flow of woodworking dust collectors. The reducer measures: Nominal 4” end is 3-61/64” OD and 3-41/64” ID; 2-1/2” nominal OD end measures 2-15/32” OD and 2-9/32” ID. Dimensions may slightly vary due to slight variations in the manufacturing process. (Chicarubber)

  1. Leak Prevention: They provide a tight seal that prevents leaks, which is essential for maintaining system integrity and preventing damage or contamination.
  2. Vibration Isolation: By absorbing vibrations, they reduce the stress on pipes and joints, preventing premature wear and potential failures.
  3. Flexibility: They allow for slight movements and misalignments in piping systems, accommodating thermal expansion, contraction, and ground movement.
  4. Ease of Installation: These couplings are easy to install and remove, facilitating maintenance and repairs.

Material and Design of 4-Inch Rubber Couplings

The effectiveness of 4-inch rubber couplings lies in their material composition and innovative design. Key features include:

  1. High-Quality Rubber: Made from durable rubber compounds, these couplings offer excellent flexibility, resilience, and resistance to environmental factors such as temperature changes, moisture, and chemicals.
  2. Stainless Steel Clamps: They are often equipped with stainless steel clamps or bands that ensure a secure, leak-proof connection. Stainless steel is chosen for its strength, corrosion resistance, and durability.
  3. Flexible Cuff Design: The flexible cuff or bellows design allows the coupling to expand, contract, and flex, accommodating slight pipe misalignments and movements.
  4. Smooth Interior Surface: The smooth interior of the coupling minimizes flow restrictions and turbulence, ensuring efficient fluid transfer.

Applications of 4-Inch Rubber Couplings

4-inch rubber couplings are used in a wide range of applications across various industries due to their versatility and reliability:

  1. Plumbing Systems: They are commonly used in residential, commercial, and industrial plumbing to connect pipes of different materials or sizes, providing a flexible and watertight joint.
  2. HVAC Systems: In heating, ventilation, and air conditioning systems, these couplings help in connecting ducts and pipes, reducing noise and vibration, and accommodating thermal expansion.
  3. Industrial Pipelines: In industrial settings, rubber couplings are used to connect process piping, allowing for flexibility and vibration absorption in systems that transport liquids, gases, or slurries.
  4. Sewer and Drainage Systems: They are ideal for connecting sewer and drainage pipes, providing a leak-proof joint that can withstand ground movement and prevent infiltration or exfiltration.
  5. Automotive Applications: In automotive systems, these couplings are used to connect various fluid lines, such as coolant or fuel lines, providing flexibility and vibration damping.
