Brass Plumbing Components Manufacturer — Turned Parts for Tap, Mixer & Fitting OEMs

The machined brass that goes inside taps, mixers and water fittings — ceramic-cartridge bodies, mixing-cartridge cores, compression and union fittings, adaptors and manifold parts. Turned and milled to your drawing in DZR and lead-free brass. We don't build finished valves; we machine the precision parts that go into them.

Critical requirement
Why DZR Brass for Potable Water?

Standard yellow brass (CW617N, CuZn40Pb2) is susceptible to dezincification in low-chloride or aggressive water conditions — the zinc selectively leaches out, leaving a spongy, weakened copper residue. This destroys the part structurally and contaminates the water.

DZR (Dezincification Resistant) alloys are specifically formulated to eliminate this. They are required by WRAS (UK), DVGW (Germany), KIWA (Netherlands), and ACS (France) for potable water contact applications.

ISO 6509-1 DZR Test
1% CuCl₂ solution at 75°C for 24 hours. Pass criterion: dezincification depth ≤200μm. All DZR alloys we supply are tested per this standard.
WRAS (UK) Approval
Water Regulations Advisory Scheme. Required for fittings in UK domestic water supply. Alloy approval is required in addition to component approval for fitted products.
EU Lead Limit (Directive 2020/2184)
Drinking water Pb ≤5μg/L at tap. UK: ≤0.10μg/L migration from component. CW724R/C69300 and C6802 meet this migration limit. CW617N does not.

DZR Alloy Selection

Choosing Your DZR Alloy

For EU and UK potable water, the alloy for your component depends on your target market's lead migration limit and the approval scheme the finished product must carry.

AlloyDesignationDZR MechanismLead ContentMachinabilityPotable-Water Suitability
CW724RCuZn21Si3PSilicon kappa-phase (intrinsic)<0.1% Pb80% Suitable for WRAS / DVGW / ACS / KIWA approved products

Buying From Us — Procurement Facts

What a Buyer Needs Before Sending an RFQ

Brassland has been machining brass components in Jamnagar, Gujarat since 2000 — 230+ people, 60,000+ sq ft of plant, and customers in more than 40 countries. Everything a procurement or sourcing engineer normally has to ask for by email is collected below, so you can qualify us before you spend time preparing a package.

QuestionHow Brassland works
What can you machine? 79+ CNC machines, including 28+ Swiss-type sliding-head lathes (Tsugami and Star). CNC turning to Ø150 mm; Swiss-type bar capacity Ø2–32 mm. Tolerances to ±0.005 mm on Swiss-turned diameters and typically ±0.01 mm on milled features.
What is in-house? CNC turning and milling are in-house, from brass bar and extruded sections, with inspection in-house. Hot forging is produced at qualified partner forges and finish-machined here. There is no casting at Brassland.
What is the minimum order? No strict MOQ. First orders typically start from around 1,000 pieces, and high-volume OEM schedules are supported. Prototypes and samples are run ahead of series production.
How fast is a quote, and a delivery? Quotations typically within 24 hours of receiving a drawing. Production lead time 3–5 weeks from the approved drawing; prototypes and samples sooner.
What paperwork comes with the parts? EN 10204 Type 3.1 mill certificate with every shipment (Type 3.2 on request), a Certificate of Conformity, and dimensional inspection reports against your drawing.
What are you certified to? ISO 9001:2015, ISO 14001:2015 and ISO 45001:2018, certified by DQS. RoHS and REACH compliant, with SVHC disclosure on request.
How do you export? Incoterms 2020 DDP, FOB and CIF as standard; EXW or DAP on request. Shipped through Mundra, Pipavav, Kandla and Nhava Sheva. HS codes 7415, 7412 and 7419. Star Export House recognised by the Government of India, shipping to 40+ countries.
Send us this and we can quote
A dimensioned drawing or 3D model, the alloy or target market, thread standard, surface finish or plating, and an indicative annual volume. If the alloy is still open, tell us the market — EU, UK or North America — and we will propose a grade from the table above.
What we do not claim
DZR and lead-free are material properties, not product approvals. CW602N resists dezincification per ISO 6509 and CW724R/C69300 meets the lead-content limit referenced by NSF/ANSI 372 — but potable-water approval of the finished product (WRAS, NSF 61, Kiwa, EU 2020/2184) is held by the product manufacturer, not by us. We supply components and the material documentation behind them.

Plumbing & Water Fittings — Frequently Asked Questions

What plumbing and sanitaryware brass components can Brassland machine?
We machine the precision brass parts that go inside taps, mixers and water fittings — ceramic-disc tap cartridge bodies, single-lever mixing-cartridge cores, thermostatic and pressure-balance cartridge parts, deck-mixer and diverter rough-in connectors, and compression, union, adaptor and manifold parts. Everything is turned and milled to your drawing in BSP, NPT or metric threads. We do not manufacture finished valves or branded taps.
Do you make the brass core inside a ceramic mixing cartridge?
Yes. We machine the brass core — the splined drive stem and sealing diameters — that sits inside a single-lever ceramic mixing cartridge, as well as the brass body of a ceramic-disc tap cartridge. We supply the machined brass part to your drawing; the ceramic plates, polymer housing and final assembly are completed by the cartridge or tap maker.
Do you cast valve or meter bodies?
No. Brassland does not cast — every part is turned and milled from brass bar and extruded sections on Swiss-type and CNC machines. If your component was previously cast, we can review the drawing and advise whether it can be produced economically from bar or from a forging (forging is brass-only and outsourced).
Which brass alloys do you use for water components?
CW724R/C69300 lead-free silicon brass (dezincification-resistant) and C6802 bismuth brass for potable-water-wetted parts, CW602N/C35330 for general DZR service, and CW617N only for non-potable or dry applications. The grade is fixed on your approved drawing and confirmed on the EN 10204 mill certificate supplied with each lot.
Can you supply lead-free brass for potable water?
Yes. For potable-water-wetted parts we machine lead-free grades such as CW724R that meet US NSF/ANSI 372 (a maximum 0.25% lead content on wetted surfaces) and the EU Drinking Water Directive (2020/2184) migration limits. We confirm the applicable limit at quotation so the correct grade is specified before production.
Do you hold WRAS, NSF 61, ACS or DVGW approvals?
No — those product approvals are held by the finished-product manufacturer. We machine your component in an alloy suitable for the scheme you are targeting (for example WRAS- or DVGW-listed CW724R) and supply material and compliance documentation; the market-specific potable approval is arranged by the buyer.
How tight are the tolerances on cartridge and sealing parts?
Our Swiss-type sliding-head turning typically holds about ±0.01 mm on critical bores, seat diameters and seal grooves, with tighter limits achievable by process where the drawing requires it. The exact tolerance capability is confirmed against your drawing at quotation.
What surface finishes and platings are available?
Parts ship as-machined in natural brass by default. Nickel, chrome, tin and electroless-nickel plating, passivation, and polished or tumbled finishes are available to your specification through qualified finishing partners; specify the finish and any thickness or salt-spray requirement at quotation.
What documentation do you provide with each shipment?
EN 10204 Type 3.1 mill certificates as standard (Type 3.2 third-party witnessed on request), a Certificate of Conformity and dimensional inspection reports, plus RoHS and REACH/SVHC declarations with commercial orders. Brassland is certified to ISO 9001, ISO 14001 and ISO 45001.
What are your minimum order quantity and lead times?
There is no strict minimum order quantity; first orders typically start from around 1,000 pieces, and we support high-volume OEM production. Typical lead time is 3–5 weeks from the approved drawing, with prototypes and samples available sooner. Quotations are issued within 24 hours.
Can you manufacture brass plumbing components to our own drawing?
Yes — made-to-drawing work is the core of what we do. Send a dimensioned drawing or 3D model with the alloy, tolerances, thread standard, surface finish and an indicative annual volume, and we will confirm feasibility, flag any feature that adds cost without adding function, and quote typically within 24 hours. Production runs only against a drawing you have approved, and that approved drawing stays the reference for every later lot.
Can we order samples or prototypes before committing to a production run?
Yes. Prototypes and first-article samples are machined ahead of series production so you can fit and test the part in your own assembly before releasing volume, and they are supplied with a dimensional inspection report against your drawing. There is no strict minimum order quantity; first production orders typically start from around 1,000 pieces, with series lead time of 3–5 weeks from the approved drawing.
Which Incoterms do you ship under, and from which ports?
We quote Incoterms 2020 DDP, FOB or CIF as standard, with EXW or DAP available on request. Shipments leave India through Mundra, Pipavav, Kandla or Nhava Sheva, and the HS codes that normally apply to brass plumbing components are 7415, 7412 and 7419. Brassland is a Star Export House recognised by the Government of India and ships to customers in more than 40 countries.
Is every shipment traceable back to the brass material batch?
Yes. Each shipment is released against an EN 10204 Type 3.1 mill certificate for the brass used, with Type 3.2 available on request, together with a Certificate of Conformity and a dimensional inspection report. The alloy is fixed on your approved drawing, so the grade stated on the certificate can be checked directly against the grade you specified.
