1.05" O.D. tube ( sold by the foot ) Now most Valves use the 1.05" size tube, which is equal to the outer diameter of 3/4" PVC pipe.
Special Thin wall SDR 3/4" Type II PVC ( O.D. = 1.05" and I.D. = 3/4" ) used in residential water filter tanks. ( sold by the foot ) is used in most water system made after 1998 and many before that date also. Was also used in some Fleck and Erie Valves. Now most Valves use the 1.05" size tube, which is equal to the outer diameter of 3/4" PVC pipe.NOTE: We will only ship pipe in 36 inch lengths or shorter. If you need a long piece, we will ship it in sections, and you would need to purchase PVC slip x slip coupler ( from local hardware store ) to connect the pieces together. We recommend you order and use the larger 1.05" O.D. distributor ( our MD1236 ) when possible, which will allow you to use 3/4" PVC pipe for your tube. Common Schedule 40 PVC ( with thicker outer wall ) can be used instead of this thin wall SDR Type II pipe. And both 3/4" PVC pipes ( SDR or Schedule 40 ) should be available locally from larger hardware / plumbing supply outlets.
