All PrePak Screens provide maximum ID for larger tools and minimum OD to fit inside smaller casings

                                   The 3/4" size is the first screen to allow larger sampling equipment than                                    will fit in commonly used 1/2" direct push wells. Usable inside most 2" or                                    2-1/8" direct push casing, or can be installed in an open hole. Each                                   section is flush threaded with an o-ring seal for assembly of longer screens. Either end attaches directly to CMP Anchor Points; flush threaded end plugs are available. The other sizes have the same design as the 3/4" but are made to install larger wells inside a larger hole or casing
