Brass fittings

Brass fittings and adaptors for irrigation and civil works

With more than 28 years dedicated to manufacturing, at Grupo Almagro we do not distribute parts: we design and produce connection solutions. Our range of brass fittings and compression adaptors for polyethylene (PE) pipes is conceived to last in the most demanding conditions of agricultural irrigation and civil works, guaranteeing performance, safety and maximum durability.

The professional choice: Advantages of our brass fittings

Professionals in the sector choose our fittings because manufacturing quality translates into peace of mind and long-term performance. The brass we use offers a set of unbeatable technical advantages.

• Superior Corrosion Resistance: Brass, an alloy of copper and zinc, has natural resistance to corrosion and oxidation. This property is fundamental in irrigation systems, where contact with moisture and chemical agents could degrade inferior materials, ensuring clean, uncontaminated flow.

• Extreme Durability and Mechanical Strength: Our fittings are designed to withstand high pressures, with peaks of up to 40 atmospheres, and to operate over a wide temperature range (-20°C to 80°C). This robustness guarantees fewer failures, minimal maintenance and a service life far longer than that of plastic fittings.

• Guaranteed Watertightness: Thanks to the precision of our machining and the use of high-quality seals (NBR or EPDM), we guarantee a perfect seal. The compression design ensures a hermetic, reliable seal that prevents any loss of water, pressure or resources.

• Versatility and Compatibility: Our fittings are compatible with low- and high-density polyethylene (LDPE/HDPE) pipes and integrate easily with other components of the installation, such as valves or strainers, thanks to their standardised threads.

Complete catalogue of brass fittings for PE pipe

Our range covers every connection need. Each piece is designed for maximum efficiency and ease of assembly. Our range includes elbows for changes of direction, tees for branches, sleeves for in-line joints (equal or reducing) and combination adaptors for connecting to threaded elements, thus covering any installation requirement.

Key applications in demanding environments

• Agricultural Irrigation and Landscaping: The robustness of our adaptors prevents breakage from water hammer or constant pressure, ensuring efficient irrigation with no water loss.

• Civil Works and Potable Water: We comply with the regulations for conveying drinking water. Brass is a safe material that does not alter water quality, ideal for service connections and distribution networks.

• Industrial Installations: They offer superior performance for conveying pressurised fluids, withstanding continuous, demanding working conditions.

Quick installation guide

1. Clean Cut: Use a pipe cutter for a 90º, burr-free cut on the PE pipe.

2. Arrange the Components: Slide onto the pipe: first the nut, then the compression ring and finally the sealing gasket.

3. Insert and Tighten: Push the pipe into the fitting as far as it will go. Seat the gasket in its housing and tighten the nut firmly with a suitable spanner.

Frequently Asked Questions

• What pressure do they withstand? They are designed for high pressures, up to 40 bar (PN40) depending on the model, offering a wide safety margin.

• Can they be used with hot water? Yes, they operate efficiently between -20°C and 80°C, making them suitable for domestic hot water (DHW) and industrial applications.

• What is the difference from polyethylene adaptors? Mechanical strength. Brass is the premium solution for critical points in the installation (pump outlets, valve connections) where long-term reliability is the top priority.

• Do I need special tools? No, only standard spanners are required. Installation is quick and needs no specialised equipment.
