What are Unbrazed U & Y Joints in HVAC systems?

Unbrazed U and Y joints are copper fittings that come as plain pieces, without any factory brazing done. This lets the installer braze them at site according to the actual piping layout, making alignment easier and helping maintain the correct refrigerant flow through the system.

What are the reasons why you would select 227 Enterprise as your Supplier of Copper Y Joint?

Due to our specialization, we are not a generic store. Our point is nothing less than high-quality VRF copper components, on-the-fly testing, and special engineering assistance on difficult projects, so you receive a committed and custom fit rather than a single-fits-all.

What would you do to make sure that your Copper Y Joints perform leak-free?

We make all the joints from high-purity copper because it gives a clean braze and a connection you can trust. After they’re formed, every piece goes through careful inspection and is pressure-tested up to 5.2 MPa, so we know it can cope with actual working conditions before it reaches site. Since the material itself is certified, the joints hold their seal for the long run, helping the whole system stay stable and free from leakage issues.

Do you manufacture VRF Copper Y Joints that are flexible to all major OEM brands?

Yep. Our 9.52mm to 34.9mm span covers that of the larger OEMs. We can also make any size, port layout, or pressure rating that you may need, which fits like a fist onto other brands such as Daikin, Mitsubishi Electric, Toshiba, LG, or any other leading VRF system.

What is the major benefit of your unbrazed design to install?

It simplifies the on-site assembly. They do not need to be pre-brazed, and thus, you can assemble and adjust the pipes first and braise them at a later stage. Such flexibility results in minimal misalignment, rapid work and a cleaner, more dependable circuit.

Does it offer tailor-made sizes or configurations beyond your normal offering?

Definitely. One of our core competencies is in custom solutions. We will develop and manufacture non-standard-size joints, special port arrangements or other special pressure requirements. Our engineering department will be with you at the same level to custom fit the exact details of your project, and therefore you will not forfeit on design.

What are the quality certifications that your products have in overseas projects?

We maintain a high level of international norms, we are RoHS and CE certified, and we provide complete material test certificates and compliance documents with each order. It is important to get green lights in areas such as the Middle East, Europe, and the southeast part of Asia with complete confidence and a smooth flow of the project.

What is the effect on the quality of copper on the performance of a VRF Y Joint?

An improved copper will lead to improved heat transfer, longevity, and an improved solid brazed joint. Low grade copper is capable of oxidizing, cracking and leaking when the system cycles, and consequently, it costs a lot to fix it. The high-quality copper makes the connection solid and the VRF system can be made long-term efficient and stable.

Do you just sell the joints, or full-fledged branch piping assemblies?

We give you both options. Take one Unbrazed U and Y Joint or select a complete VRF Refrigerant Branch Piping Kit, everything in one box, all joints, reducers and insulation, plus pick it up with one hand. It reduces purchasing inconveniences, and standardizes parts, and maintains quality.

Which technical selection or design support do you have?

We have the team to assist in spec to install. We will select an appropriate product to your OEM, capacity, and layout requirements, provide you with CAD drawings to approve and guide you to the right installation practice. Through the rich product expertise we have, we assist the consultants and contractors to construct faster, smarter and more reliable systems without committing costly errors.
