I ordered this part hoping it would arrive within 2 weeks because I had an emergency situation with an employee waiting to repair a piece of equipment at a customer’s location. The part actually arrived halfway across the country in 5 days including the weekend. MRO processed, packaged and shipped it with incredible speed. Thanks again!

Excellent customer service

The couplings are just what they are supposed to be. But I wanted to comment on MRO. This was my first order with them and I was extremely surprised at how well the company is run. I will be doing more business with them in the future.
