LG Series
Refrigerant Branch Piping Kit for all types of VRF Systems working on R410 Refrigerant
227 Enterprise Pvt. Ltd. manufactures LG Series branch pipes for smooth VRF installations. Each set includes precisely formed copper Y joints for suction and discharge lines with matching reducers for quick fitment. The multistep connection design reduces site brazing and ensures secure, leakproof performance over time.
The LG Series is offered with two insulation options: UV stabilised fire-grade XLPE and NBR. Both help prevent sweating at refrigerant joints while handling heat and moisture effectively. This added protection keeps nearby areas clean, supports steady system performance, and ensures dependable long-term operation across different VRF installation conditions.

What is the LG Series Branch Pipe?
It is a prepared refrigerant pipe system kit of VRF. It has copper Y-joints and reducers that divide the flow directly in the middle of the inside units to make zoning efficient and reduce the amount of spot-on-site assembly and brazing.
Does it work with any VRF brands?
Yep! Its multi-step design is compatible with virtually any major brand of VRF. That is one of the solutions to a collection of projects.
What is the pressure rating of these joints?
All pieces are stamped out using 5.2mpa pressure test. That is more than normal, and thus you will be assured of a leak-free seal and a long-lasting stability even in harsh conditions.
Which insulation types can be used?
Choose between UV stabilized Fire Grade XLPE or flexible NBR. They are both laser-cut to fit snugly to prevent sweating and maintain the thermal performance of the lineup, in addition to being resistant to moisture throughout life.
Are the associations leak-proof?
Totally. Each component undergoes a 5.2 MPA pressure test, which is fabricated with accuracy of copper and ingenious design. This holds the system in place, the refrigerant contained, and the environment intact.
How long does it normally take to deliver?
They have ready stock to be immediately dispatched. Normal orders take 3-5 business days to reach any part of India, or you can use express shipping in case you are in a hurry.
Is it possible to demand a personalized kit?
Definitely. 227 Enterprise is a company of custom solutions. Ask them your layout as it is, the size of pipes, and what you want to be connected to, and they will charge you a custom quote.
Are they certified products?
Yes, all LG Series components are made in line with RoHS and CE requirements. That means they’re safe for use and meet the environmental and regulatory expectations for projects in different parts of the world.
What does this kit do to decrease installation time?
The multi-step design is meant to make life easier on site. Because the components come pre-made and accurately sized, there’s far less cutting and brazing required during installation. That means fewer measurements to double-check, less manual work, and a lower chance of mistakes. In the end, the whole job moves faster and more smoothly.
What guarantee or maintenance do you give?
You get a 6-month warranty that covers any manufacturing faults. If a joint happens to leak because of a production defect, we’ll simply replace the VRF Y-Joint, no runaround.
