Straight lengths of oxygen barrier type PEX pipe, also commonly called "PEX sticks" for common hydronic heating applications - baseboard and radiator piping, radiant heat manifolds, boiler/heating system piping (circulators, air vents, etc.), fan coils and many others.
Straight PEX pipe is an effective alternative to coiled PEX tubing, which, although convenient for long pipe runs, presents a challenge due to inherent coil memory (regardless of type - PEX-A or PEX-B) when installing in confined spaces.
They are also a great alternative to common straight copper pipes due to a significantly lower cost.
PEX sticks we sell are PEX-B type, made in the USA by Sioux Chief and are compatible both with crimp connection method & fittings and PEX-A expansion method & fittings.
