Brass components

Are you a plumbing installer who cannot risk a valve leaking at the first pressure fluctuation? Are you a wholesale distributor who must supply compliant, fully traceable, and consistently available components? In both cases, the answer lies in material quality and complete control over the manufacturing process.

At Novasfer, brass forging and precision brass machining are carried out entirely within the Brescia industrial district in Italy, using state-of-the-art CNC machinery and a quality control system that monitors every part from raw brass bar stock to final testing. No step is outsourced, and no compromises are accepted.

Hot Brass Forging: Guaranteed Strength and Structural Integrity

The production cycle begins with hot brass forging, the process that defines not only the shape of the component but also its intrinsic structural properties. Brass bars are heated to temperatures between 650°C and 750°C until they reach a plastic state, then pressed into high-precision metal dies using mechanical or hydraulic presses.

Unlike casting, hot forged brass components develop a dense, fibrous structure free from internal porosity. What does this mean in practical terms for installers and distributors? Components that withstand constant pressure, repeated thermal cycles, and mechanical stress for decades—without cracks and without leaks. This is the technical foundation on which the safety of every plumbing and heating system is built.

Our hot brass forging in Brescia reflects a manufacturing tradition that has reached the highest level of specialization in this industrial district, now fully integrated with advanced industrial automation technologies.

Precision CNC brass machining: From raw forging to finished component

The forging of brass fittings and valve bodies gives each part its shape and strength. However, to become a fully functional component—ready for installation on-site or distribution through supply channels—a second phase of extremely precise CNC brass machining is required.

Our workshops are equipped with CNC machining centers that perform brass turning, milling, drilling, and threading operations with tolerances measured in hundredths of a millimeter. Every thread complies with international standards (ISO, UNI, NPT) to ensure perfect fit with the rest of the system, eliminating the need for adapters or field drilling.

Brass valve machining requires the utmost care in sealing surfaces: O-ring grooves, ball seating surfaces, and stem threads are dimensionally verified piece by piece. For brass hydraulic fittings, every sealing profile is inspected for roughness and perpendicularity before release.

Brass plumbing fittings: complete range for installers and distributors

Novasfer’s brass plumbing fittings cover the full range of needs for contractors and wholesale distributors: straight fittings, elbows, tees, reducers, nipples, couplings, and custom parts, all manufactured through hot forged brass fitting production and CNC threading.

The non-porous structure guaranteed by brass fitting forging is essential for potable water applications, heating circuits, and gas systems: no microcracks, no delayed leakage, and no costly return service calls. For wholesalers, this means fewer returns, fewer complaints, and stronger credibility with installer customers.

Brass ball valves: certified shut-off for water and gas

Brass valves are among the most critical components in every plumbing, heating, and sanitary system. The body of our brass ball valves is produced through hot brass valve forging, ensuring superior structural resistance to impact and operating pressure.

The internal ball is positioned with micrometric precision to ensure leak-tight shut-off and smooth operation even after years of service. Our range is divided into two product lines:

• Water valves: designed to resist limescale and wear in residential and industrial systems, with long-life PTFE seats.
• Gas valves: manufactured to comply with stricter regulations and supplied with certifications that guarantee full compliance and absolute safety for gas networks.

CNC brass valve machining ensures that sealing tolerances meet design specifications on every single part produced, not only on qualification samples.

Brass Components for boilers, heat pumps, and solar thermal systems

Modern heat generation systems—condensing boilers, solar thermal systems, biomass heating, and heat pumps—require brass components capable of withstanding more demanding operating conditions than ever before: higher temperatures, aggressive fluids (glycol-based and demineralized), and more frequent thermal cycling.

• Condensing boilers and biomass systems: we manufacture fill valves, thermal relief valves, and circulation fittings designed for continuous operation in environments with aggressive condensates.
• Solar thermal: Novasfer brass accessories for solar systems are engineered to resist prolonged exposure to glycol fluids and high thermal stress, ensuring long-term durability and sealing performance.
• Heat pumps: for these high-efficiency systems, we provide dedicated heat pump accessories designed to optimize connection and hydraulic circuit management. The precision of our brass hydraulic fittings ensures leak-tight connections with minimal pressure drop, contributing to overall system efficiency.

Safety components and meter accessories

Pressure management is critical in any system. We manufacture safety valves and brass ball valves for meters to the same standards of strength and dimensional precision as our main product range. These components are installed at critical points in the system, where every millimeter of tolerance can determine whether the installation passes final certification and testing.

OEM Production and Custom Solutions for Wholesalers and Distributors

For wholesale distributors seeking a supplier capable of ensuring consistent quality, predictable lead times, and product flexibility, Novasfer is a supply chain partner—not simply a subcontractor.

Our engineering department designs custom brass components: fittings with special threads, valve bodies with non-standard dimensions, and semi-finished brass parts for in-house assembly. Every project starts from a technical drawing or functional specification and is manufactured through hot brass forging and CNC brass machining with the same quality standards as our standard production.

FAQ — Brass Forging and Machining

What is the difference between hot forging and casting for brass plumbing components?

Hot brass forging creates a dense, fibrous structure without internal porosity, ensuring superior mechanical resistance to tension, pressure, and fatigue. Casting, by contrast, may generate microscopic air inclusions that can become critical points of failure or leakage over time, especially in components exposed to repeated thermal cycles such as valves and fittings.

Are Novasfer brass fittings and valves certified for potable water and gas?

Yes. Our gas valves comply with stricter sector-specific standards and are supplied with the relevant compliance certifications. Fittings and valves for potable water are manufactured using brass alloys that comply with current regulations for contact with water intended for human consumption. Contact us for technical documentation related to your specific application.

Does Novasfer manufacture custom brass components for wholesalers and distributors?

Yes. We produce OEM solutions based on drawings or technical specifications: fittings with custom threads, valve bodies with specialized geometries, and semi-finished brass parts for assembly. Our technical office supports the customer from design through prototype validation, with both small batches and large-scale production managed to the same quality standards.

What does “controlled supply chain” mean for an installer or wholesaler?

It means that every phase—from brass bar sourcing to hot forging, from CNC brass machining to final dimensional testing—takes place entirely within our Brescia facility. There are no third-party subcontractors and no lots of unknown origin. Every component is fully traceable, and dimensional compliance is certified on every single piece, not only on sample batches.
