Gas & water distribution · Metering and control hardware
Die-cast and machined housings, sensor and solenoid covers, and valve bodies for gas and water metering and pressure control. The value is in the sealing face, the port thread and the finish, not in the pound of metal, so that is where the machining and the inspection go.
01 — The parts we make for this industry
Housings, covers and bodies are the core of the program. Caps, stems and sleeves ride on the same PO, so the whole assembly ships from one supplier with one inspection standard.
Die cast in ADC12 aluminum at a partner foundry, then machined at our lead CNC plant: gasket faces flat to print, cable-entry and port bores, tapped mounting bosses. Powder coat, applied by a partner plant, for outdoor service.
Machined from 6061 aluminum at our lead CNC plant: pockets, counterbored fastener holes, clear or colored anodize applied by a partner plant, sealed. The cover that keeps moisture out of an electronics or solenoid cavity.
Aluminum bodies die cast and brass or bronze bodies sand cast by partner foundries we manage. Both bored, faced and threaded ANPT/NPT at our lead CNC plant.
Die-cast or machined aluminum heat sinks, brackets and mounting plates for the electronics inside metering and control boxes.
Turned in 52100 or C1117 steel, matched to the body they seal into; threaded inserts and bushings for field-serviceable assemblies.
Turned pipe caps, plugs and DOM-tube stiffeners, quoted as part of a housing or valve program rather than as stand-alone commodity lots.
02 — What actually matters on these parts
None of these are cosmetic. A miss on any one of them is a leak claim, a corroded fitting in the field, or a seal that never sat flat.
ANPT and NPT threads are gauged against that standard, in the same inspection pass that checks bore concentricity and finish. They are not sampled after the fact.
Salt-spray results for plated or coated parts are available on request, with the test standard confirmed in the quote. RoHS-compliant blue trivalent chromate zinc plating or oil-dip rust protection is specified by exposure, not by default.
A burr on a thread crest or a gasket face cuts the seal on first assembly. Deburring is checked at the same station as the dimensional inspection, not left to a downstream sort.
Machined bores on castings hold ±0.025 mm with GD&T concentricity to Ø0.003 in. An off-axis bore loads a seal unevenly, and it will weep under pressure eventually.
03 — Typical routing by part family
Process route, material and finish for the part families above, with each step marked lead CNC plant or partner plant. Volumes, exact routing, production site and origin are confirmed in the quote.
| Part family | Process route | Material | Finish |
|---|---|---|---|
| Meter & electronics housings | Die casting (partner foundry) + CNC machining (lead CNC plant) | ADC12 aluminum | Powder coat (partner plant) |
| Sensor & solenoid covers | CNC milling (lead CNC plant) | 6061-T6 aluminum | Anodize, clear or color, sealed (partner plant) |
| Regulator & valve bodies | Die casting or sand casting (partner foundries) + CNC machining (lead CNC plant) | ADC12 aluminum / brass / bronze | Polish (lead CNC plant); plate, pad print (partner plant) |
| Stems, shafts & inserts | CNC turning (lead CNC plant) | 52100 / C1117 steel | Zinc plating (partner plant) |
| Caps, plugs & sleeves | CNC turning (lead CNC plant) | 12L14 / A513 DOM tube | Zinc, RoHS trivalent chromate or oil-dip (partner plant) |
04 — One part, one supplier
A representative routing for this industry, with each step marked where it is done. The quote names the production site and country of origin.
ADC12 housing cast to near-net shape on dedicated production tooling at a partner foundry.
Gasket face, cable-entry bores and tapped bosses cut to print in one setup at our lead CNC plant.
Sealing faces and thread crests dressed clean at our lead CNC plant — the step that decides whether it leaks.
Powder coated for the exposure the housing will see, then pad-printed, at a partner plant.
Flatness and thread check to our inspection plan, individual bagging, cartons under 30 lb; the quote names where this is done.
05 — Where we are the wrong shop
We do not hold NSF/ANSI 61 or an equivalent potable-water contact certification. If your part touches drinking water directly and that approval is required, confirm it with us before tooling. We will tell you honestly whether we can pursue it, or whether you need a different supplier for that part.
We machine the part to your print and have it finished to your spec. We do not certify an assembly for ATEX or a similar hazardous-area rating — that qualification sits with your engineering team at the assembly level.
Turned-feature tolerance is confirmed against your drawing in the written quote. If a critical bore or diameter needs a very tight tolerance, say so on the drawing and we will tell you plainly if it is outside what we can hold.
06 — Before you send a drawing
Short answers here; the rest on the FAQ page.
ANPT and NPT threads are gauged against ANSI/ASME B1.20.1 limits in the same inspection pass that checks bore concentricity and finish. Tell us your acceptance sampling plan and we will quote against it.
Not today. We do not hold NSF/ANSI 61 or an equivalent certification. If that approval is required for your part, tell us before you send a drawing. We will be honest about whether it is worth pursuing for your volume.
Minimum order quantity is set per part and process, and confirmed in the written quote. Our cost advantage comes from tooling amortized over production volume, so if your volume is too low for us to be competitive we will tell you rather than quote badly.
STEP or PDF, one part or a whole family. You get a unit price at your volume, the tooling cost and the lead time, plus a note on the thread and finish callouts. Turnaround is 48 hours.
