Our A621 is a very popular stock housing or pressure vessel, and is ideal for small diameter equipment. It is rated to 2,100m and has a fixed Packaging ID of 5.82'' (148mm) and packaging length of 18'' (457.2mm) Custom lengths are also available. Contact Prevco for a quote.


The standard lengths are 12,18 and 24'' (304.8mm - 457.2mm - 609.6mm) but we stock the raw tube material so they can quickly be made in almost any length. The housing can be fitted with a conical frustum Acrylic window for use with camera's, lasers etc. or for applications where it is important to be able to see in or out of the enclosure.

The model quoted is what we call 'barefoot' without modifications. This means that the endcaps would not be anodized, there would be no pressure testing and there would not be a vent plug included. If you would like us to quote for connector interfaces, brackets, pressure relief valves or chassis etc. please use the request a quote tab and let us know what you need!
