Quality You Can Check, Not Just Believe.
Four checks decide whether a fitting survives the sea, your warehouse and the machine it lands on: plating, corrosion, thread precision and sealing. This page lists what we control on the floor and what each check changes on your side.
Trivalent Zinc (Cr3+) on Everything We Ship
Every part that leaves the workshop is zinc plated in a trivalent chromium (Cr3+) bath. That is 100% of production, not a premium finish added to selected part numbers when a buyer insists on it.
We do not run hexavalent chromium. A trivalent bath is not the cheapest way to put a coating on a fitting, but it takes a restricted-substance question off your desk: nothing in the coating that your own customers, or your customs paperwork, have to argue about.
96 Hours of Neutral Salt Spray, Before the Sea Gets a Chance
Fittings spend more time in a container and on a warehouse rack than most buyers plan for. If the coating gives up early, the rust appears on your shelf, not on ours.
Every batch runs through a 96-hour neutral salt spray test. It is the check that decides whether parts arrive clean after weeks at sea and stay presentable in storage — instead of blooming white rust in the first weeks after arrival, before the carton is even open.
Salt Spray, in Numbers
Threads Held Above General-Factory Practice
A fitting that will not start by hand is a fitting your customer sends back. Ours are CNC machined and checked with optical thread gauges — not by eye, and not on one sample pulled from the top of the crate with the rest assumed to match.
The tolerance we hold sits above general-factory practice. On a part that is threaded, gauged and deburred before plating, the joint seals the first time and keeps sealing once the pressure cycles start.
The Stations a Batch Passes Before It Is Packed
Three checks stand between the machine and the export crate. The slots below are reserved for the photos of those stations.
Every Batch Leaves With Its Check Record
Plating, corrosion and thread results are tied to the batch they came from, so a question about a delivery is answered from the record rather than from memory. Ask the export desk for the record on the batch you are buying.
What We Check, and What It Changes For You
One row per checkpoint, with the difference it makes on your side of the order rather than another slogan about quality.
Batch Checkpoints
| Checkpoint | Our Standard | What It Changes For You |
|---|---|---|
| Plating | Trivalent zinc (Cr3+) on 100% of production | Eco-compliant coating, no hexavalent chromium to explain to your customers |
| Corrosion | 96-hour neutral salt spray | Parts survive sea transit and warehouse storage without rust bloom |
| Thread precision | Held above general-factory practice | Threads mate with the port and the hose end first time, without rework |
| Sealing | Rust, thread and sealing performance controlled batch by batch | Fewer weeping joints and blown O-rings in the field |
| Service cycle | ~12 months on quality-grade parts — low-grade parts fail at 6–7 months | Fewer replacement rounds per year, lower total cost for your end users |
| Certificates | EU & US market-access certificates available on request | Clears your local compliance and customs checks |
The Same Fitting, Two Ways to Make It
What a workshop that treats coating and thread as process controls delivers, and what turns up when they are treated as cosmetics.
✓ How We Run It
- Cr3+ on the whole run: the same trivalent zinc bath for every part number, on every order.
- 96-hour salt spray per batch: the test is part of the process, so a coating problem shows up here rather than in your warehouse.
- Threads gauged, not eyeballed: CNC threading with optical thread-gauge inspection.
- Sealing faces deburred before plating: a clean cone seats first time.
- Batch-level records: results tied to the batch you were shipped, checked against the confirmed specification.
- A known service cycle: about 12 months on quality-grade parts, where low-grade parts fail at 6–7 months.
✗ What We Do Not Do
- No hexavalent chromium in the plating line — nothing restricted to declare.
- No treating plating as an optional extra you have to negotiate for.
- No thread check by eye, and no single sample standing in for a whole batch.
- No visible burrs left on a sealing bevel for the O-ring to deal with.
- No rust appearing within weeks of arrival, while the parts are still on your shelf.
- No claim of quality without a batch record behind it.
Market-Access Paperwork, Sent With the Quotation
We hold EU and US market-access certificates for the fittings we export, and send them on request — no account, no form, no waiting for a print run.
Documents We Hold
What This Page Does Not Show, and Why
The plan for this page also calls for a salt spray test video and third-party comparison reports. We have not published either, because we do not have them: no footage has been filmed for release, and no third-party report on a competitor's fittings sits in our files.
Rather than run an edited clip or borrow somebody else's result, the two slots beside this text are left open and labelled. What we can send today is what we hold: the EU & US market-access certificates and the test record behind the batch you are buying.
Ask for the record behind your own batch
Send the part list and the export desk returns the certificates we hold, the Cr3+ plating declaration and the test record for the batch you are buying — first reply within 2 working hours.
