Shielded couplings connect Cast Iron hubless soil pipe and fittings in sanitary and drain waste and vent (DWV) applications. For non-pressure, gravity flow applications only.
Multiple sizes from 1 1/2” to 10″.
No-Hub couplings have an inner gasket made of a synthetic rubber compound, polychloroprene (neoprene). The inner gasket is surrounded by an outer stainless steel shield or band with stainless steel worm clamps strategically riveted to the shield to keep them in place. Series 300 stainless is used for corrosion resistance. With the use of a No-Hub Torque Wrench, the installer applies 60 inch-pounds torque to the 5/16″ hex-head screw for optimum and proper assembly.

What are the Maintenance Requirements for Stainless Steel Couplings to Ensure Their Longevity?
To ensure the longevity and optimal performance of stainless steel couplings, regular maintenance is essential. The maintenance requirements for stainless steel couplings typically include:
- Regular Inspection: Conduct routine visual inspections of the coupling to check for signs of wear, corrosion, or damage. Inspect the coupling’s fasteners and ensure they are properly tightened.
- Lubrication: Some stainless steel couplings may require periodic lubrication of the moving parts to reduce friction and wear. Follow the manufacturer’s guidelines for the appropriate lubricant and frequency of application.
- Cleaning: Keep the coupling clean from debris, dirt, and contaminants. Regularly clean the coupling using appropriate cleaning agents to prevent the build-up of foreign particles that could lead to accelerated wear.
- Alignment Check: Verify that the shafts connected by the coupling are properly aligned. Misalignment can lead to increased stress on the coupling and reduce its service life. If misalignment is detected, take corrective measures to realign the shafts.
- Torque Check: Periodically check the torque on the coupling’s fasteners to ensure they are properly tightened. Loose fasteners can result in coupling slippage and potential failure.
- Replacement of Worn Parts: If any components of the stainless steel coupling show signs of wear or damage beyond acceptable limits, they should be promptly replaced with new parts from the original manufacturer.
It is important to follow the maintenance schedule recommended by the coupling manufacturer. Different applications may have specific maintenance requirements based on factors such as operating conditions, torque levels, and environmental exposure. By adhering to proper maintenance practices, operators can extend the lifespan of the stainless steel coupling, reduce the risk of unexpected failures, and ensure consistent and reliable performance in their mechanical systems.
Causes of Failure in Stainless Steel Couplings and Prevention
Stainless steel couplings are designed for durability and reliability, but like any mechanical component, they can experience failure under certain conditions. Understanding the potential causes of failure and taking preventive measures can help ensure the longevity and performance of stainless steel couplings. Some common causes of failure include:
1. Overloading: Exceeding the maximum torque or load capacity of the coupling can lead to deformation or breakage. To prevent overloading, it’s essential to choose a coupling with the appropriate torque and load ratings for the specific application.
2. Misalignment: Misalignment between shafts can create additional stresses on the coupling, leading to premature wear and failure. Regularly inspect and adjust shaft alignment to ensure it stays within the coupling’s allowable limits.
3. Corrosion: While stainless steel is corrosion-resistant, it is not immune to corrosion, especially in harsh environments with exposure to corrosive substances. Regular cleaning and maintenance can help prevent corrosion-related failure.
4. Fatigue: Repeated cycles of loading and unloading can cause fatigue failure in the coupling. Ensure that the coupling’s rated fatigue life matches the application’s requirements and replace worn-out couplings promptly.
5. Installation Errors: Improper installation, such as insufficient tightening of set screws or improper keyway fitting, can lead to coupling slippage and failure. Follow the manufacturer’s guidelines for correct installation procedures.
6. Contamination: Foreign particles or debris can get trapped between the coupling’s mating surfaces, leading to uneven loading and premature wear. Keep the coupling and surrounding area clean to avoid contamination-related issues.
7. Temperature Extremes: Extreme temperature variations can affect the material properties of the coupling and lead to failure. Choose couplings rated for the temperature range of the application.
8. Vibration and Resonance: Excessive vibration or resonance can cause stress concentrations in the coupling, leading to fatigue failure. Dampen vibrations and resonance using appropriate mounting and isolation techniques.
9. Material Defects: Occasionally, manufacturing defects in the stainless steel coupling can cause premature failure. Source couplings from reputable manufacturers with a track record of quality and reliability.
Preventive Measures: To prevent failure and ensure optimal performance, consider the following preventive measures:
- Choose the right coupling type and size for the application’s torque and load requirements.
- Regularly inspect and maintain the coupling, checking for signs of wear, misalignment, or contamination.
- Ensure proper installation following the manufacturer’s guidelines.
- Monitor operating conditions and address any unusual vibrations or temperature variations promptly.
- Perform regular shaft alignment checks to avoid excessive misalignment.
- Use protective measures such as seals or covers to prevent contamination and corrosion.
- Monitor coupling fatigue life and replace worn-out couplings before they reach their fatigue limit.
By understanding the potential causes of failure and implementing appropriate preventive measures, users can increase the reliability and longevity of stainless steel couplings in their applications.
Types of Stainless Steel Couplings
Stainless steel couplings come in various designs and configurations to suit different application requirements. Some common types of stainless steel couplings available in the market include:
1. Clamp-Type Couplings:
These couplings consist of two hubs with screws or clamps that tighten around the shafts to create a secure connection. Clamp-type couplings are easy to install and provide good torque transmission while accommodating shaft misalignments.
2. Oldham Couplings:
Oldham couplings have a unique three-piece design with two hubs connected by a center disk. The disk is made of a different material like acetal or nylon and allows for zero-backlash operation and misalignment compensation.
3. Jaw Couplings:
Jaw couplings are made of two hubs with elastomeric inserts, known as spider elements, that provide shock absorption and misalignment compensation. They are commonly used in pumps, compressors, and other machinery.
4. Disc Couplings:
Disc couplings consist of multiple thin stainless steel discs stacked together with spacer elements. They offer high torsional stiffness and are suitable for applications requiring high torque transmission and precision.
5. Bellows Couplings:
Bellows couplings use thin-walled stainless steel bellows to compensate for misalignments while maintaining a hermetic seal. They are commonly used in vacuum systems and applications requiring precision motion control.
6. Grid Couplings:
Grid couplings feature a flexible grid element between two hubs, providing excellent shock absorption and misalignment compensation. They are commonly used in heavy-duty applications.
7. Multi-Beam Couplings:
Multi-beam couplings have multiple beams that offer flexibility and compensate for misalignments while maintaining torsional stiffness. They are suitable for precise motion control applications.
Each type of stainless steel coupling has its unique advantages and is designed to meet specific performance criteria. When selecting a stainless steel coupling for a particular application, it is essential to consider factors like torque requirements, misalignment compensation, and environmental conditions to ensure optimal performance and longevity.
