The use of brass fittings in Irish plumbing has a variety of benefits, not least tolerance to high temperatures and durability in water systems.
As the only brass fittings to be certified by both the Water Regulations Advisory Scheme (WRAS) and the National Standards Authority of Ireland (NSAI) from ½” to 2” in size, South Brass fittings are the first choice for thousands of plumbers nationwide. And for good reason.
South Coast Sales, the leading supplier of water connections in Ireland, manufactures South Brass fittings from CW617N brass to EN 1254-2 to ensure plumbing suppliers around Ireland can equip plumbers with the highest standard of fittings for top quality jobs which stand the test of time.
Suitable for commercial and domestic installations, South Brass fittings are versatile, durable, superb at handling high temperatures and are corrosion resistant.
Here are just a few of the many reasons to stock South Brass fittings in your store and why the most conscientious plumbers like to use them.
The Plumbers’ choice of above-ground fitting
When connecting water pipes above ground, South Brass fittings are the number one choice of brass fitting for plumbers in Ireland. That’s not only because South Brass fittings are easy to fit and built to last – there’s much more to it.
South Brass is also the Irish plumber’s first port of call when working with hot water distribution systems, due to the components’ fantastic conductivity and ability to improve efficiency.
Where poor water PH conditions exist, South Brass fittings are more than capable of handling the job due to excellent corrosion and rust-resistant properties. The ability of brass to withstand even the worst water conditions is a key reason why the plumbing trade in Ireland trust South Brass where water neutrality is a little off – and we all know how common that is!
South Coast Brass leading the way with ease of use with Flats
The Flat head products ensure the installer has full control of the South Brass fittings on compression and prevents the fittings from slipping, in comparison to round body brass fittings. Holding the compression fitting body on the Flats tightly with an adjustable spanner and tightening the nut with an open-ended spanner helps exert pressure on the olive and bites it into the pipe giving peace of mind on every compression. See the Flat in action here.

Why is NSAI certification important for brass fittings?
National Standards Authority of Ireland (NSAI) is Ireland’s official standards body. They provide accredited certification of products, services, and organisations for compliance with recognised national and international standards. It issues certification confirming the quality and safety of goods and services produced and traded in Ireland.
What is WRAS approval?
Water Regulations Advisory Scheme (WRAS) supports safe, resilient water supplies. They protect public health by helping to keep safe to drink and never wasted. WRAS checks the testing of thousands of water fittings products to ensure they comply with the relevant water regulations. Plumbing products are considered suitable if they pass appropriate material and mechanical regulatory performance tests.
Why is EN 1254 important?
The EN 1254 standard provides specifications for fitting ends to ensure plumbing fittings provide water-tight and secure connections. EN 1254-2 covers compression ends for copper tube.
What is CW617N brass?
The name brass covers a wide range of alloys, but they are fundamentally a combination of copper and zinc, with other elements being added to increase the strength, malleability, ductility, or resistance to corrosive attack.
It is used in many engineering applications as well as decorative ones. Typical applications include component and equipment manufacture in a variety of industries.
CW617N is classed as a stamping brass with excellent hot forming properties and high machinability. With these characteristics, this alloy is used extensively in the production of more complex hot-pressed components.
What is ISO9001?
ISO 9001 is an international quality standard that helps ensure that customers get consistent, good-quality products and services. ISO 9001 sets out the criteria for a Quality Management System (QMS).
This standard is based on several quality management principles including a strong customer focus, the motivation and implication of top management, the process approach and continual improvement.
