Knuckle Joint Casing Swab
The Guiberson Knuckle Joint casing swab is of basically the same design
as the knuckle joint tubing swab and offers the same advantages of quick
change and versatility. The swab is made of high-strength, heat-treated
steel and is individually tested to withstand the heaviest swabbing
loads. It is designed for use with Types J and JS cups or (10) Type
V cups and two mandrels. Cups may be changed in a matter of seconds,
with no tools required.

service. An internal bypass, two-cup swab, the standard will accommodate
two Type J, JS, or GW cups; one Type UF cup; or (10) Type V
cups. Ample bypass through the valve and around the swab assures fast
falling and reliable operation.
