SWT Slotted Riser Tubes are machined from high quality PVC pipe, slotted, and plugged at one end. The other end is available with either a chamfered slip connection or MNPT adapter. The open area of slots in the riser tube is engineered to be equal to or greater than 1.5 times the cross-sectional open area of the pipe. This insures minimal pressure drop when in service. Made in USA.
