Product Name:Copper Line Set with Nuts
Description:

Copper line set with nuts, air conditioner pipe, insulated copper pipe

Usage: Used for mini split air conditioner, and both ends flared and nuted to make easier connection. The copper tube inside of insulation with different wall thickness is compatible for R410a, R407c, R404, R507 and R22 refrigerants. The insulation is made of closed cell structure, made of PVC/NBR, no CFCs, conform to RoHS standard. The flammability is classified Class One according to BS 476: Part 7 standard.

Advantage:
1. CE certificate, RoHS certificate and ISO 9001 management system assure superior quality
2. Professional copper tube manufacturer, fast production and delivery
3. 100% pure copper:
Unlike many other split connection line set brands that are made of aluminum, our line sets are 100% pure copper. Aluminum (CU-AL) is cheaper than copper so many brands are starting to produce aluminum line sets to save on cost. However, aluminum cannot be cut or reduced like the industry standard copper lines. And most importantly, aluminum lines will result in a loss of energy efficiency. The Thermal conductivity is much greater in copper than aluminum (around 60%), so the short term savings of aluminum line sets will result in higher utility costs in the long term.
4. Rubber foam insulation tubes are with closed cell structure, made of PVC/NBR, no CFCs, conform to RoHS standard, with RoHS certificate.
5. Rubber insulation tubes are classified Class One according to BS 476: Part 7 standard, with Class One certificate
