Parker stainless steel and aluminum Sample Cylinders provide safe containment for both storage and transportation of gas or liquid samples.

The design, manufacture, and testing of stainless steel sample cylinders is regulated by the US government (DOT-3A 1800 and 3E 1800). Aluminum cylinders must also comply with DOT-E 7737.

Stainless steel cylinders are hot spun from seamless Type 316 tubing. This process provides a smooth internal flow transition through the neck for easy cleaning and the elimination of potential trapped fluids.

Aluminum cylinders are produced from 6061 material and are heat treated to T6 temper. They have the same DOT ratings and quality control as stainless steel cylinders, with half the weight.

Stainless steel cylinders are available in 75 through 2250 cc and one gallon capacities. Aluminum cylinders are available in 150, 300, and 500 cc capacities. All employ 1/4-18 NPT female threads except for the one gallon size which uses 1/2-14 NPT female threads.
