Eldon James 3/8-19 BSP to 1/2" Barbed Adapter, Non-Animal Derived Polypropylene BSPT threads have on the Whitworth thread form, which is designed to provide a pressure-tight fit through mating of the threads. This is accomplished by cutting the threads on a taper. Because they are tapered, the thread can only screw into the companion female thread a certain distance before it jams. The standard specifies this distance as a length based on hand-tight engagement; a convenient rule-of-thumb for plastic threads is: finger-tight plus 1/2 to 1 turn with a wrench. Do not over-tighten plastic threads stress on the fitting can result in its failure. Features: A polypropylene formulated for biomedical and bioprocess applications. Temperature Range -9 F to 150 F (66 C) Pressure 125 psi at 70 F. Meets FDA requirements 21 CFR 177.1520(a)(3)(i) and 3.1a. PP material has a Drug Master File listing. It is radiation stable and is resistant to solvents, chemicals, water and other inorganic environments. Resists most strong mineral acids and bases; however, it is subject to attack by oxidizing agents.
