Fluid & Flow Components

Mechanically, from inside the bore, and without rounding over the land next to the port. That land is frequently the surface a seal runs against, so an aggressive deburr that leaves a clean-looking edge can still ruin the part. It is worth being explicit on the drawing: state the edge condition or radius you need, because 'deburred' is interpreted very differently by different suppliers and it is the single most common cause of a spool that will not seal.

Yes, but flag it as a functional dimension rather than just a diameter. A metering orifice is one of the few features where deburring and edge break directly change the part's function — open the edge up and the flow changes even though the bore still measures correctly. Tell us it is a flow-critical feature and we will control the edge as well as the diameter, and discuss whether flow testing on samples makes sense.

No — we machine to your drawing and can hold the sealing geometry a rating depends on, but we do not run proof or leak testing and cannot issue a pressure certification. If your part needs it, tell us at enquiry so we can agree who does it and what documentation ships with the parts. We can supply material certification where the material is bought to a standard that provides it.

Brass machines freely, seals well and suits general fluid hardware, which is why so much of it is brass. 303 stainless machines better than 304; 316 costs more and is the choice where corrosion resistance matters, including most marine and chemical service. Aluminum is for weight and cost where the fluid and pressure allow it. If you tell us the medium, temperature and pressure we will comment on the choice rather than just quoting what you ask for.

We can wash, dry and pack to suit the service, and we handle instrument and gas-system parts differently from general hydraulics. What we cannot do is certify to a formal cleanliness class with particle counts. If your application needs that, say so at enquiry: it affects handling, packaging and cost throughout, and it is much cheaper to plan for than to add afterwards.

Yes — the filter cartridges above are machined flanges with mesh welded in. The constraint is that the weld has to seal at the joint without blinding the mesh next to it or distorting the flange it is welded to, so the sequence and heat input matter. Tell us the mesh specification and the open area you need to preserve, and whether the flange face has to stay flat after welding, because that usually decides the approach.
