Questions buyers ask
What gases is it compatible with, and has it been oxygen cleaned?
The listing states compatibility with "all standard industry gases," and the title indicates H2 and methane service. The listing does not specify whether this unit has been oxygen cleaned or is suitable for oxygen service—brass regulators can be used with oxygen but require specific cleaning and compatible lubricants. Ask the seller whether this unit is cleaned for oxygen or sold for inert/fuel gas only.
What materials are the wetted parts?
Wetted components include a brass body and bonnet, PTFE (Teflon) seat, neoprene diaphragm, and an internal filter (material not specified). The gauges are brass construction but gauge internals typically include bronze Bourdon tubes and may have additional elastomeric components depending on the service intent.
What should I inspect before putting it into service?
Since this is new and unused in original packaging, verify the packaging seal is intact, check all gauge faces for damage during shipping, and confirm the inlet and outlet threads match your system (CGA connection standard not listed). Before pressurizing, ensure the adjustment screw is backed out fully, inspect the diaphragm and seat through the bonnet if accessible, perform an external leak test at your operating pressure, and verify smooth pressure adjustment through the full delivery range while monitoring both gauges.
