Line set LS38341250EZ pairs a 3/8" OD liquid line with a 3/4" OD suction line in a 50 foot length, insulated with 1/2" wall EZ-Pull insulation. It is stocked as a Daikin Universal Parts item; the EZ-Pull line set line is manufactured by JMF and the same part number is used across the trade.

The insulation is a CFC and HCFC free closed-cell low-density polyethylene foam with a tough outer skin designed to resist tearing while the set is pulled through framing or conduit. JMF rates the 1/2" wall at R3.3, lists a 25/50 flame spread and smoke developed rating per ASTM E84, and states the jacket is UV resistant and paintable. The jacket carries foot-by-foot length markings.

Tubing is commercial grade refrigeration copper, alloy C12200 DHP, meeting ASTM B743 and ASTM B88.
