Viega 11458 – Frequently Asked Questions
1) What size and length is Viega PEX 11458?
Viega part 11458 is 3/4 inch barrier PEX supplied on a 500 foot coil. One coil weighs 56.5 lbs, so plan on two people or a cart to move it off the truck. The coil measures 29.5 inches across and about 8.5 inches through the roll, which matters if you are stacking them in a van or a storage cage.
2) What does barrier PEX mean and do I need it for a radiant floor or hydronic loop?
Barrier PEX carries an oxygen diffusion barrier in the tube wall, which is what a closed hydronic system needs when it has cast iron or steel components, a cast iron circulator body, or a steel boiler. Oxygen migrating through plain PEX corrodes those parts over time. The Viega 11458 is barrier PEX, so it is the right choice for radiant floor loops, baseboard, and snowmelt. For domestic hot and cold water distribution you do not need the barrier.
3) Does Viega 11458 PEX work with Viega PureFlow press fittings?
It is 3/4 inch nominal PEX, so it takes standard 3/4 inch PEX fittings sized to the same nominal dimension, including Viega's own PureFlow line. Fittings are not included with the coil, so order your 3/4 inch elbows, couplings, manifold adapters, and the sleeves or rings your fitting system uses as a separate line.
4) Is Viega PEX tubing made in the USA?
Yes. The 11458 coil is manufactured in the USA, which is what a government, school district, or federally funded job needs to satisfy domestic sourcing language in the spec.
5) How much 3/4 inch PEX is on a coil, and how many coils for a radiant job?
Each Viega 11458 coil holds 500 continuous feet. Since 3/4 inch is typically the manifold trunk or a long supply run rather than the loop tubing itself, count your longest runs and add for drops and turns. Buying the 500 foot coil rather than short lengths lets you pull a run with no couplings buried in a slab or a wall.
6) How is this PEX sold, by the foot or by the coil?
By the coil. The 11458 is a fixed 500 foot put-up of 3/4 inch barrier PEX, not cut-to-length, so ordering one unit gets you the full 500 feet.
