BALL LOCK OIL SAVERS
The use of the Ball Lock Oil Savers by drilling and production departments
has earned this service proven tool a reputation for trouble-free operation with
simplicity. The CAVINS Ball Lock Oil Savers (Fig. 1) are made of high carbon
steel and precision machined for demanding dependability and safety in a wide
range of service applications. Exhaustive testing in the excess of 3000 psi is fur-
ther assurance against failure or leakage. Incorporated in its design, which
affords a cleanly wiped wire line, is its safeguard against blow out. One impor-
tant feature of the Oil Saver is its automatic ball release design. Hardened Steel
Balls hold the traveling assembly securely in the body until released by the
upward travel of the Rope Socket. The Rubber Packing unit with its internal fins
provide the ultimate in wire characteristics with only a normal pressure, or drag,
on the line.The Packing Rubber is compounded of special abrasive and oil resis-
tant properties to give the rubber longer wear. A tough spark-proof die cast alloy
is utilized in the top and bottom line guides and enhances reduced wear in the
rubber packing unit. A high quality leather hydraulic packing ring wards against
leakage in the area between the body and the traveling assembly.
The Steel Hydraulic Bonnet is Standard Equipment for Cavins Ball Lock Oil
Savers. The Hydraulic Bonnets provide an even greater degree of wiping effi-
ciency. The wire line can be completely stripped of all oil, or water and an Oil
Saver outfitted with a Hydraulic Bonnet foregoes the necessity of tools for “tak-
ing up” wear in the packing element. The one hand operation requires only a few
strokes of the pump handle to give complete wiping action or turn the release
valve when no wiping is required. The Hydraulic action affords a greater rubber
contact surface as the packing rubber is compressed around the line. The line is
completely surrounded and sealed from blow-out leakage by the action of the
Hydraulic unit. There is no danger of packing rubber or other elements falling
into the well.
The Ball-Lock Oil Saver is
standard with the popular
Steel Hydraulic Bonnet. It
is completely reliable for
efficient line wiping action
and is designed to reach
maximum utilization of the
Packing Rubber
The optional Hydraulic Bonnet is a self contained
unit and features a Bonnet pump and Handle for
ease of operation. Fig. 2
