Detailed description

Overshot


GAOTON Series 150 Releasing and Circulating Overshot is an external fishing tool for engage, pack off and  retrieve tubular  fish, especially for fishing drill collar and drill pipe. The grapple of  the overshot can be designed for different sizes of fish, so one overshot can be dressed with different size of grapple components for fishing different sizes of fish.

Construction
GAOTON Series 150 Overshot consists of three outside parts: Top Sub, Bowl, and Standard Guide. The Basic Overshot may be dressed with either of two sets of internal parts, if the fish diameter is near the maximum catch of the Overshot, a Spiral Grapple, Spiral Grapple Control, and Type “A” Packer are used. If the fish diameter is considerably below maximum catch size (½” or more) a Basket Grapple and a Mill Control Packer are used.

When order please specify:
●The model of the overshot
●The hole, casing size or o.d. of overshot
●Top connection
●O.D of the fish

Overshot Accessories are available: Extension Sub, Wall Hook Guide, Oversize Guide, Mill Extension, Mill Guide.
