Brassland is a precision brass-component manufacturer in Jamnagar, India, supplying turned and milled fittings to drip, sprinkler and micro-irrigation OEMs and agricultural-equipment exporters in 40+ countries. We machine spray nozzles, barbed fittings (8/12/16 mm), BSP threaded connectors, flow regulators, pressure-compensating dripper parts and manifold tees and elbows — from CW617N free-machining brass, CW602N (DZR) for aggressive water and lead-free CW724R for potable supply lines. Every part is made to your drawing on Swiss-type and CNC machines and inspected in-house, referencing ISO 9261. ISO 9001, ISO 14001 and ISO 45001 certified. Choosing the grade?

Lead-Free & Low-Lead Brass for Potable Irrigation

Where drip and sprinkler lines connect to the drinking-water mains, the rules on lead in water-contact brass have tightened on both sides of the Atlantic. For potable-contact parts we machine dedicated low-lead and lead-free grades in place of standard leaded brass.

Why it matters

Standard free-machining brass such as CW617N carries 1.6–2.2% lead to give clean cutting and good chip control. That lead is what newer drinking-water rules restrict on any surface the water touches.

In North America, the Safe Drinking Water Act — as amended by the Reduction of Lead in Drinking Water Act, in force since 2014 — defines "lead-free" as a weighted average of no more than 0.25% lead across all wetted surfaces. Lead content is verified to NSF/ANSI 372, while NSF/ANSI 61 covers how much may migrate into the water.

In Europe, Drinking Water Directive (EU) 2020/2184 lowers the lead limit in water toward 5 µg/L and introduces European positive lists of accepted materials (building on the 4MS common composition list). They list the accepted alloy compositions and the components they may be used for, rather than one lead percentage, and apply from 31 December 2026 — national lists until then.

CW724R — Lead-Free Silicon Brass

CuZn21Si3P. Lead-free (Pb ≤0.10%), with high strength (R500–R670: Rm ≥500–670 MPa) and good machinability (85, the CDA rating of C69300) — on the European positive list (entry 1658, product groups B–D) and well suited to pressure-bearing potable fittings and PPR-type connectors.

Lead-freeHigh strength

CW511L — Low-Lead DZR Brass

Lead ≤0.2% with no lead added, and arsenic for dezincification resistance. Suited to soft or chloride-rich water — where dezincification risk is highest — and to buried fittings. Not on the European positive list.

≤0.2% PbDZR

CW510L — No-Lead-Added Brass

Pb ≤0.2% with no lead added — a reduced-lead alternative to CW617N, on the European positive list as CW510L-DW (product groups B–D). It is not dezincification-resistant: where the water demands DZR, use CW724R / C69300.

≤0.2% PbDry-side

We machine these grades to your drawing and supply EN 10204 Type 3.1 mill certificates for the material. Brassland is certified to ISO 9001, 14001 and 45001; product-level potable approvals — NSF/ANSI 61 & 372, WRAS, or acceptance under the European positive list — are specific to the finished component and are arranged by the buyer. Tell us your destination market at quotation and we will match the right grade.

Recommended Alloys for Irrigation & Agriculture

  • CW617N (standard)
  • CW602N (DZR — dezincification resistant in aggressive water; contains lead)
  • CW614N (free-cutting)

Key advantage: CW602N DZR brass resists dezincification in aggressive — soft or chloride-rich — water supplies — ideal for buried or outdoor irrigation systems.

Irrigation — Frequently Asked Questions

Which brass grades suit outdoor irrigation use?
CW617N for general fittings and CW602N DZR brass where soft or chloride-rich water calls for dezincification resistance; CW602N contains lead, so drinking-water lines take lead-free CW724R. We advise on the right grade for your water and climate.
Can you machine fittings to my drawing and thread standard?
Yes — couplings, nipples, adaptors, nozzles and valve bodies are turned and milled to your drawing in BSP (ISO 228 parallel / ISO 7 taper), NPT or metric threads.
Do your parts meet potable/drinking-water rules?
We machine the part to your specification and chosen grade. Final product approvals such as WRAS, NSF/ANSI 61, or acceptance under the European positive list are specific to the finished component and are arranged by the buyer. Low-lead and lead-free grades suitable for those schemes are available — see the lead-free section above.
Do you offer lead-free or low-lead brass for drinking-water lines?
Yes. For drinking-water lines we machine the lead-free silicon brasses CW724R and C69300 and the low-lead, dezincification-resistant CW511L; CW510L (no lead added) is not dezincification-resistant and suits waters that do not demand DZR. Their lead content is within the US potable limit — a weighted average of 0.25% lead on wetted surfaces under the Safe Drinking Water Act (verified to NSF/ANSI 372). The EU sets no single lead percentage for brass: under Drinking Water Directive 2020/2184, alloys are accepted through the European positive list, which applies from 31 December 2026 and names CW724R (entry 1658) and CW510L (as CW510L-DW), but not CW511L or C69300 as such. Tell us your destination market and we will match the grade.
Which standards apply to irrigation fittings?
Emitters and emitting (drip) pipe are specified by ISO 9261. Threaded connections are cut to BSP (ISO 228 / ISO 7), NPT or metric, and dezincification resistance of water-grade brass is verified to ISO 6509-1. We machine to these references and supply EN 10204 mill certificates for the material.
What documentation do you provide?
EN 10204 Type 3.1 mill certificates as standard (3.2 third-party witnessed on request), a Certificate of Conformity and dimensional inspection reports, plus RoHS and REACH declarations with commercial orders.
What is your minimum order quantity and lead time?
There is no fixed minimum order quantity — the batch size is quoted from your drawing and annual quantity, and we support high-volume production for OEMs. Typical lead time is 3–5 weeks from approved drawing, with prototypes and samples sooner.
