Viega’s FostaPEX form-stable, multilayered tubing for plumbing and radiant heating applications pairs the flexibility of PEX with the stability of rigid piping. The Viega FostaPEX press tubing has a low coefficient of expansion compared to standard PEX products. Available in sizes of 1/2” to 1”, the tubing is only compatible with ViegaPEX Press fittings and features form stability to keep its shape after its bent, as well as an exterior aluminum layer which acts as an oxygen barrier for heating applications.
