Identify the complete assembly
Collect the vessel or housing brand, complete model, end-cap arrangement, port photographs and any available drawing. Similar-looking membrane housings may use different seals, adapters and connection layouts.
Measure the interface
Confirm nominal size and standard, thread or joint type, sealing surfaces, available installation space and the parts included in supply. A nominal pipe size or a visual comparison alone does not confirm fit.
Check rated conditions and materials
Review the relevant pressure and temperature limits, process liquid and material compatibility against the actual model documentation. Changes to a pressure-containing assembly require assessment of the complete assembly and an appropriate competent party.
Send one coordinated replacement request
Include the housing, seals, adapters, brackets and required accessories in the same list. State quantities, destination and whether the original model must be retained.
