Line set LS38341225EZ pairs a 3/8" OD liquid line with a 3/4" OD suction line in a 25 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. It is the 25 ft counterpart to LS38341250EZ.

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.

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