I have been ordering parts from this company for almost a year now. The orders I place are always accurate and the promised delivery date has always been met. The staff are very knowledgable, professional and polite. I highly recommend them for any business, in town or out of state.My rep Michael Wade has gone above and beyond for us several times and his expertise has saved us on more than one occasion. I couldnt be more satisfied with St Louis Fluid system technologies, Swagelok or Mr. Wade and the office staff at Millpark Dr. I am with a small company and I feel like they treat my account like it was Boeing or GE, always getting my order confirmed ASAP and shipped same day.Thanks again!
