Well Screen 4 ft. x 5 ft. 0.010 in. Slot w/ Plug. This premium quality PVC Pipe is precision machined, cleaned and bagged to prevent contamination and meet environmental standards. Each piece of pipe has a Male and Female threaded end that join together to make a flush union that does not require any glue or tape. By eliminating the need for couplings, you can reduce the overall diameter of your hole and prevent snagging your pipe as it enters the hole. This thread is made to industry standards and should work with any existing flush thread pipe you have.
