*KeyFeatures *【RELIABLE PEX MATERIAL】- Color: Red & Blue; Nominal Diameter: 1/2", Total Length: 300 ft. Outside Diameter: 5/8"; Inner Diameter: 1/2"; Keep quick & smooth hot/cold water flows. Made of PEX material, non-toxic, crack-proof, leak-proof. Perfect for potable water or radiant floor water use. *【ROBUST O2 RESISTANCE】- Unique EVOH layer, stop O2 into the tube, protect metal components from corrosion. This non-broken 1/2" PEX tube can tackle different weather circumstances, no matter the high or low temperature, to ensure the integrity and safer use for longer life expectancy. *【PREMIUM FLEXIBILITY】- Min.5" bending radius, easy to bend for different ground situation. Compatible water temperature: -40℃ to 95℃/-40℉ to 203℉. Big pressure capacity: 80psi @ 200℉, 100psi @ 180℉, 160psi @ 73℉. Thus, to ensure its good temperature resistance, crack- & leakage-proof. *【EFFORTLESS INSTALLATION】- Compatible with different connection system & floor type, such as: Crimp connection system (crimp tool + crimp rings + crimp fittings); Cinch (clamp) connection system (cinch tool + St. steel clamps + crimp fittings); Press system (by Viega); Compression PEX Fittings. *【DIVERSE USE SCENARIO】- Suit for home & commercial use, like radiant floor heat system, solar water heater system, central air-conditioning piping system etc. Structural concrete slabs, Non-structural slabs, Staple-up (between joists) radiant floor heating with and without heat transfer plates, "Sandwich" type radiant heating (between subfloor and finished floor), Snow & ice melting systems etc. ******************************************************************************************************* *Specifications Type: PEX-B Tube(Oxygen Barrier) Color: Red & Blue Total Length: 300 ft/91.4 m Nominal Diameter: 1/2"/1.2 cm Inside Diameter: 1/2"/1.2 cm Outside Diameter: 5/8" / 1.6 cm Tube Thickness: 0.07" / 1.8 mm Pressure Ratings: 80psi @ 200F, 100psi @ 180F, 160psi @ 73F Min.Bending Radius: 5"/12.7 cm ANSI/NSF 14, ANSI/NSF61, NSF-Pw (certified for radiant heating applications).
