This 3/4 inch x 3/4 inch male NPT thread adapter connects a range of ID (inside diameter) nominally sized polyethylene pipe, tube, and hose with varying wall thicknesses. It is re-usable and eliminates the need for multiple replacement parts. A double barbed insert connection works with a captive nut to secure and grip to the surface area on the pipe for a leak free connection. The maximum pressure is 230 psi and maximum temperature is 140 degrees F.
