What Customers Are Saying

“I have been purchasing flanges from API International for a few years now and most recently check valves, expansion joints etc. They always have exceptional quality of their products and a wide selection. Between their two warehouses, they have what I need in stock 99.9% of the time and ship within a day of receiving the purchase order. RIck Runckel and his team have been top notch to us with customer service, handling our orders, quoting products, and anything else we may need. Highly recommend them as a supplier!”
