Great Value
For the price, you cannot beat the quality. Shipping was fast. Just make sure to measure your shaft diameter accurately before ordering.

Durable and Reliable
We use these for multiple fan units. They have been running for 6 months without any wear on the spider insert. Highly recommend for high-torque apps.

Reduced Noise Significantly
Replaced an old rigid coupling with this elastic jaw type. The noise reduction in the pump room is noticeable. Very happy with the purchase.

Perfect for Air Compressor
Installed this on my industrial air compressor setup. The alignment was off slightly, but this coupling absorbed the vibration perfectly. Solid steel construction.

Good Quality, Tight Fit
The material quality is excellent. The keyway was a bit tight and required some filing, but overall it holds torque well without slipping.

A: The standard elastic insert is rated for continuous operation up to 80°C (176°F).
Q: Is this suitable for underwater pump applications?
A: The steel has a black oxide coating, but for submerged applications, we recommend additional corrosion protection or stainless steel variants.
