[Heavy Duty] Our air compressor line 300 feet kit features a three-layer HDPE pipe (HDPE-AL-HDPE) crafted from copper and nickel for unparalleled leak-proof pressure performance. With smooth interior walls, our piping rolls outshine traditional iron or PVC piping, ensuring rust-free operation and heightened efficiency. It reliably maintains pressure at 200 psi@73F / 160 psi@140F and meets ASTM F1282, F1974 standards. [Flexible Fittings & Pipes] The FIDEURSUS air line kit boasts a 1/4” NPT port on the front of the manifold, complemented by 1/2” NPT ports on the top, front, and back, as well as a 3/8“ NPT port at the bottom (for connecting the Drain valve), catering to diverse needs. Equipped with 1/4” & 1/2“ couplers, the flexible 3/4-inch pipe bends easily to desired shapes with a bending radius of 6-8 inches. For tighter bends, an L-Fitting can be added in the middle.
