Copper Tee Joint

Custom‑Engineered for Peak VRF/VRV Performance

In progressive VRF/VRV systems, one outdoor unit connects with several indoor units through refrigeration piping. The Joint that is necessary to divide refrigerant flow correctly is the Copper Tee Joint. Each joint is designed to fit into a R410A system, with all being precision designed with copper construction suction and liquid lines.
The Multi-Step/universal design of the tee joint is designed so as to be easily fitted with all pipe sizes. This will provide OEM compatibility, less inventory on-site, and will provide a leak-sealed seal through rigorous testing during pressure test of 5.2 Mpa to achieve maximum system efficiency and reliability throughout its range of life.

What is copper tee joint and how do we use it in VRF systems?

The copper tee joint is a three-way joint that separates the flow of refrigerant of one primary line into two branch lines. It is a very essential component in VRF/VRV systems as it ensures that refrigerant is pumped into each indoor unit correctly. Well-constructed tee joints ensure that the system pressure does not go high or low, eliminating leaks, and ensuring the entire network operates effectively to keep cool and warm.

What are the copper tee joints that 227 Enterprise has?

We supply both equal tee joints (all the ends the same size) and reducing tee joints(1 or 2 ends different size) to suit the various piping plans. Each of the types is available in an entire volume of standard VRF pipe sizes (such as 1/2 -inch, 5/8 -inch, 3/4 -inch, 7/8 -inch, et cetera) and can be made to your precisely drawn specifications.

Which is the pressure rating of your copper tee joints?

Our shop pressure-tests each 227 Enterprise copper tee joint at 5.2 to 754 754 754 754 754 754 754 754 754 754 754 754 754 754 754 754 754 754 754 754 754 754 754 754 754 754 75 It is greater than the standard operating pressure of R410A and other common types of refrigerants, thus assuring you of a 100 per cent leak proof enclosure and long life in the field.

The tee joints are compatible with the major VRF OEM brands?

Yes. Our Multi -Step design also allows one joint to connect directly to the large variety of pipe sizes, making it universal and compatible with Daikin, Mitsubishi Electric, LG, Samsung, Fujitsu, and other leading brands of VRF. This reduces branded inventory as well as simplifies ordering to the contractors.

What is your quality and life expectancy assurance of your copper tee joints?

Our copper tubes are of high-purity, all the joints are braid using rods of 2percent or more silver-contents, and each fitting is taken through rigorous visual, dimensional checks, as well as pressure checks. Our production is also certified by ISO and also we comply with the requirements of ROHs and CE, thus you can be assured that the product is always good.

What are the benefits of the installation of your tee joints?

Tee joints have been machined to easy fit. Smooth inner bores also minimize the pressure drops and the insulation required is also pre-applied to prevent sweating. Multi -step design reduces the adapters and hence you can build quicker and save labor cost during on-site construction.

Does it offer custom made copper tee joints to meet special project needs?

Absolutely. Being a specialty or custom-oriented manufacturer, we do custom tee joints to fine drawings in non-standard angles, special port arrangements or custom insulation. We can give you a customised solution with you just by providing your specs and our engineering team will give it to you.

What are the certifications of your products?

The tee joints of our copper are fabricated in an ISO-certified production plant and they meet ROHS, CE and other standards of the HVAC market. On every batch, we offer pressure-test certificates, which has given you quality and conformity.

How long is your average lead time of orders?

On standard sizes, our delivery time is 710 working days. Bespoke joints can require 2-3 weeks to make and test. We maintain an inventory of common sizes on a stratified basis to assist with an urgent project timeline.

How do I ask a quote or technical support of my project?

All one has to do is to mail [email protected] with the project specifics, piping scheme, and quantity requirement. Our friendly technical sales staff will come over with a competitive quote, specifications and installation instructions at your VRF system.
