Herose Cryogenic Strainer 15mm — 9.0 Bar Stainless Steel

What pressure, flow and temperature is it rated for?

This unit is rated to 9.0 bar pressure. The listing does not specify flow capacity or temperature range; ask the seller for the mesh size, Cv rating, and minimum design temperature to confirm suitability for your cryogenic application. Cryogenic strainers in this size class are typically rated for LIN/LOX service down to -196°C, but you'll need confirmation from the seller or nameplate data.

What gases is it compatible with, and has it been oxygen cleaned?

The stainless steel construction is described as suitable for cryogenic service, but the listing does not specify which gases it has handled or whether it has been oxygen cleaned. Ask the seller for the previous service history and oxygen cleaning certification if you're planning LOX or GOX duty. Strainers for oxygen service require documented degreasing and must remain hydrocarbon-free throughout their service life.

What should I inspect before putting it into service?

Pull the strainer element and check for mesh damage, corrosion, or previous cryogenic embrittlement cracks in the body and bonnet. Inspect all threads, seat surfaces, and verify the stem packing or gaskets are intact—used cryogenic equipment often has hardened or missing seals. Hydrostatic test to verify integrity at the 9.0 bar rating and confirm there's no prior impact damage to the inlet/outlet connections.
