12 Polypipe Patches in a Kit. Each 6"x6" patch can be cut to smaller sizes as needed. (Up to 48 3"x3" patches.) Poly Patch features a strong adhesive that works on dry and wet surfaces...even UNDERWATER. This peel and stick patch for polypipe works on holes and blow outs. The patch will not come off as it withstands more pressure than the poly pipe itself.
