Complete Tubing Wear Solutions
NOV Mono has been providing effective tubing wear solutions for over 70 years. Whether using beam pumping
units or progressing cavity downhole pumps, NOV Mono offers the most complete package of tubing wear solutions
including tubing rotators, rod rotators and rod guides. Among the benefits resulting from the utilization of these
products are:
•Greater rod and tubing service life
•Decreased workover costs
•Reduced downtime
Today’s producers are constantly seeking solutions that allow them to maximize production while minimizing
downtime. One of the most significant factors influencing these issues is tubing wear prevention. Tubing wear
affects horizontal, directional and slant well completions, as well as older conventional completions.
NOV Mono, with its lineup of RODEC Tubing Rotators and Swivels, offers a wide range of products designed to
effectively distribute wear evenly around the entire internal circumference of the production tubing. The application
of these products can dramatically increase tubing life span and reduce operating costs proportionately.

RODEC TUBING ROTATOR SOLUTIONS
RODEC Slimline Tubing Swivel
Engineered to meet demanding applications requiring a tubing swivel, the RODEC Downhole
Tubing Swivel allows for installing and removing mechanically set tools. Working in conjunction
with a RODEC Tubing Rotator, it enables the tubing string to be rotated during production while
keeping the downhole pump anchored.

•
•
•
•
Mechanical clockwise rotation setting/counter-clockwise rotation unsetting.
Reduced outside diameter.
Redundant seals to protect against wellbore fluids.
Extended length on the pin thread for applying power tongs.
RODEC Anchor Catcher Swivel
The RODEC Anchor Catcher Swivel has been engineered to be used in conjunction with a right
hand set anchor catcher in applications where the production tubing is installed in tension. The
AC Swivel allows for mechanically setting the anchor in clockwise direction upon installation;
the tubing can then be pulled into tension and rotated during production.
Features & Benefits
• Mechanical clockwise rotation setting/counter-clockwise rotation unsetting.
• Redundant seals to protect against wellbore fluids.

RODEC Tubing Rotator Drive Options
RODEC Tubing Rotators are compatible with various pump systems. For reciprocating rod pump installations,
operation is accomplished by means of a pull chain clamped to the walking beam. Additionally, manual and electric
models for both reciprocating and PC pump systems are offered. Once operational, RODEC Tubing Rotators require
essentially no maintenance or monitoring by oilfield operators.
Precise Torque Control
To prevent tubing from becoming
over-torqued, all tubing rotators are
engineered with a RODEC Torque
Limiter.
Ultimate,
RII
and
High
Temperature models incorporate a
Clutch Assembly type torque limiter
which clicks to indicate that the tubing
has become stuck or sanded in. It is
relatively maintenance free and doesn’t
require field service, resetting or
repinning after use.
Model C rotators incorporate a Shear
Collar type torque limiter which limits
the amount of torque transferred to
the tubing by inserting shear pins as
determined by the tubing structural
rating.
CAUTION: Operating a tubing rotator
without a torque limiter may result in
damage to tubing and other equipment.
