Eldon James 1/4-19 Bsp To 1/4 Barbed Elbow, High Density Polyethylene

Bspt Threads Are Based 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; However, 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.
