1302 Nylon Bushing

All thread sizes (3/8 x 1/4 to 2-1/2 x 2) of AquaTechnic Bushings are made with a heavy hex for wrenching. The nylon bushings are somewhat pliable and must be tightened securely. Also, the thread tapers are designed so that some flow of the nylon into inaccurate metal threads will occur if the thread size is within the specifications of the American Standards Institute.
