Appleton EC-200 Threaded Union 2″ Mall Iron Coupling Pack of 5

Description

Product Overview

The Appleton EC-200 threaded union coupling is engineered for demanding industrial environments where reliability and precision are paramount. Constructed from high‑grade Mall‑type iron, the bellows core offers exceptional resistance to corrosion, wear, and temperature extremes, ensuring a long service life even under continuous operation. The 2‑inch (50 mm) size aligns with standard shaft dimensions, providing a seamless fit for a variety of machinery without the need for custom adapters.

Designed with a threaded union interface, the EC‑200 allows quick installation and removal, reducing downtime during maintenance or equipment upgrades. The precision‑machined threads guarantee a tight seal that prevents fluid leakage, while the flexible bellows absorb axial, angular, and radial misalignment, protecting downstream components from stress and vibration. This combination of strength and flexibility makes the EC‑200 an ideal choice for power transmission systems that demand both durability and adaptability.

Each package contains five couplings, offering a cost‑effective solution for projects that require multiple connections or spare parts for future repairs. The couplings are lightweight yet robust, weighing approximately 9.24 lb each, which simplifies handling and installation while maintaining the structural integrity needed for high‑torque applications. The product dimensions of 10 × 7 × 3 inches provide ample clearance for easy access during assembly.

Appleton, a trusted name in industrial components, has a long history of delivering high‑performance products that meet rigorous industry standards. The EC‑200 complies with relevant ISO and ANSI specifications for flexible couplings, ensuring compatibility with a broad range of equipment across sectors such as manufacturing, energy, and HVAC. Its proven track record is reflected in its ranking as #59 in the Flexible Bellows Couplings category on major e‑commerce platforms.

Overall, the Appleton EC‑200 threaded union coupling delivers a balanced blend of strength, flexibility, and ease of use, making it a reliable component for any system that requires efficient power transmission and protection against mechanical stresses.

Usage

The EC‑200 is suited for a wide range of industrial applications where flexible power transmission is essential. It excels in HVAC systems, connecting motor shafts to fans, compressors, and pumps while mitigating vibration that can lead to premature wear. In pump installations, the coupling’s ability to accommodate slight misalignment reduces the risk of seal failure and extends the lifespan of both the pump and the driven equipment.

Beyond HVAC, the EC‑200 is frequently employed in material handling equipment, such as conveyors and mixers, where torque fluctuations and shaft misalignment are common. Its robust iron bellows can handle high torque loads, making it appropriate for heavy‑duty machinery in manufacturing plants, metalworking shops, and processing facilities. The coupling also performs well in marine and outdoor settings, thanks to its corrosion‑resistant construction.

Installation is straightforward: the threaded union ends can be hand‑tightened or secured with standard tools, and the bellows can be inspected visually for any signs of damage before assembly. The pack of five ensures that users have sufficient inventory for multi‑point installations or future maintenance, reducing the need for emergency part orders.

FAQ

What size shafts are compatible with the EC‑200 coupling?

The EC‑200 is designed for 2‑inch (50 mm) shaft diameters, which is a common standard in many industrial machines. It can accommodate slight variations in shaft size due to its flexible bellows, but for optimal performance we recommend using shafts that match the specified diameter.

Can the EC‑200 be used in high‑temperature environments?

Yes. The Mall‑type iron construction is rated for elevated temperatures up to 250 °F (121 °C) without loss of mechanical integrity. This makes the coupling suitable for applications such as heat exchangers, steam turbines, and other equipment that operates under high‑heat conditions.

How does the threaded union interface improve maintenance?

The threaded union allows technicians to quickly disconnect and reconnect the coupling without the need for specialized tools or extensive disassembly. This feature reduces maintenance time, lowers labor costs, and minimizes the risk of damaging adjacent components during service.

Is the EC‑200 suitable for marine or outdoor installations?

Absolutely. The iron bellows are treated to resist corrosion from moisture and salt exposure, making the EC‑200 a reliable choice for marine vessels, offshore platforms, and outdoor equipment that may be exposed to harsh weather conditions.

What warranty does Appleton provide for the EC‑200?

Appleton offers a one‑year limited warranty covering material defects and workmanship. Should any issues arise within the warranty period, our support team will arrange for repair or replacement, ensuring your operations continue with minimal interruption.
