1/2″ VesiFlow Red PEX-a Expansion Tubing UVGuard, (100 ft Coil)


PEX-a is the most flexible PEX tubing available. The flexibility allows this product to be expanded to fit all the different fitting connections, including F1960 and F2080. PEX-a is very easy to install, the flexibility allows for the use of less fittings, creating less pressure loss in the system.

1/2″ Red VesiFlow PEX-a tubing is made using the Engel or high temperature peroxide method. The Engel method is a hot cross-linking process, meaning the actual cross-linking takes place during the extrusion process when the base polyethylene is above its crystal melting temperature. The Engel method provides more precise control over the degree, consistency and uniformity of cross-linking. This means the tubing is evenly cross-linked, with no weak links within its molecular chains.

UVGuard from VesiPex is certified 5106 pex for chlorine and uv resistance. UVGuard is also certified fire rated under ASTM E84 & cNSF®-fs ULc S102.2 with flame and sm0ke spread FS≤25/SD≤50
