Our reputation here at Greenco/Duramaster expands over 45 years of knowledge and expertise. We have always used the finest Quality Materials for our pnuematic cylinders such as aluminum 6061 precision machined components and name brand Parker seals. Don’t be fooled by other pnuematic cylinders on the market that have inferior components and many parts or assembly that is done oversees. We are proud to manufacture all of our pnuematic cylinders here in Tampa, FL USA. We cater to a variety of customers all over the world which is why we have “played” on the word pnuematic versus pneumatic cylinders. Many of our foreign customers use the spelling of pnuematic cylinders and we capture that audience. We appreciate all customer’s business whether in the USA or abroad and we hope to keep supplying you with quality pnuematic cylinders for many years to come.
