JACO Polypropylene Fittings
JACO polypropylene fittings have good chemical resistance and are unaffected by most weak acids and alkalies. Below 175°F, they have good resistance to organic solvents. They should not be used with oxidants, strong acids, or in continuous sunlight. Polypropylene is a workhorse in the plastics industry. Though polypropylene is similar to high-density polyethylene, it is harder, more durable, and more rigid. Polypropylene is light weight and extremely valuable for high purity applications such as deionized water. The polypropylene used in JACO fittings is 20% glass filled for improved stiffness, and is NSF listed.
