We Manufacture and Stock Domestic Flanges and Fittings Made In The U.S.A.

"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!"

"API is by far one of our best and most reliable suppliers. The quality of the products we purchase is excellent and the pricing is very competitive. I have been buying from them for well over 20 years and have had the opportunity to get to know many of the people there. Always a pleasure to work with!"

"I have zero complaints about their service. I would list API in the top three of our vendors with exceptional customer service. In a time when most companies have forgot how to spell customer service, let alone give any customer service, API is a pleasure to deal with. The main reason the customer service is so good is that I don’t have to think about dealing with API. I never have to follow up. I never have to give something with API a second thought, answers and quotes are fast and right."
