Home of the Slimline® Tubing Anchor
TechTAC® offers a suite of tubing anchor products designed to accommodate a wide range of downhole conditions and tool assemblies.
Our innovative Slimline Tubing Anchor Catcher offers up to 245% more flow-by area than a standard B2 anchor, helping to mitigate gas interference and sediment buildup.
The new Slimline Full Bore TAC is a patent-pending tubing anchor that combines a full bore ID (2.40" on the 5.5" model) with an OD similar to the original Slimline anchor.
The patent-pending Slimline QuickSet TAC sets in just 1-to-3 turns, as opposed to the traditional 6-to-8 turns, while still benefiting from the Slimline design.
TechTAC carries the most common sizes of traditional B2-style TACs, which have been used in the industry for decades to minimize wear on rods, tubing and casing.
The right-hand set Quarter-Turn Tension Anchor is a rugged, compact, automatic-released anchor that can be set with minimal surface rotations and is easy to redress.
Watch below to learn how the innovative Slimline TAC can mitigate many common downhole problems that hinder production in wells that use sucker rod pumps.
For two decades, TechTAC has supported service companies, field operators and engineers by holding fast to a core set of values:
Every product we create meets the highest standards of quality, being manufactured and assembled in the USA. We strive to bring innovation to every market we serve, because we're always trying to find a better way.
We’re dedicated to building lasting customer relationships, and our goal is to consistently exceed our customers' expectations. We conduct business with integrity and authenticity – always doing what we say we will do.

How does the downhole performance of a traditional B2-style tubing anchor compare with TechTAC’s Slimline TAC?
To answer that question scientifically, TechTAC commissioned a computational fluid dynamics (CFD) study conducted by the independent consulting firm Imaginationeering. The study provides “a comparison CFD analysis of a gas flow within the annular space around two types of a 5.5-inch tubing anchor catcher to assess the differences between them in terms of flow parameters.” Specifically, the analysis evaluated the performance of the anchors relative to fluid velocity, pressure drop, turbulence, vorticity and other factors.
One of the most significant findings of the CFD study dealt with the pressure drop around each tubing anchor. Researchers found that the net pressure drop around a standard B2 tubing anchor catcher, as fluid/gas passes through the annular cavity around the anchor, is more than double the pressure drop around the Slimline TAC.
<p”>According to the study: “…the pressure drop along the standard TAC is more than double that drop along the Slimline TAC. This is expected because the annular cavity with the Slimline TAC’s case is wider than that for the standard TAC’s case. Furthermore, the pressure drop change in the Slimline TAC’s case is less abrupt than that in the Standard TAC’s case….”
The Slimline tubing anchor also demonstrated a noticeable advantage over the standard TAC in reducing the overall turbulence and vorticity strengths within the flow field.
The report noted, “The observed abrupt changes in the pressure field along with the potential presence of flow field obstacles in the case of the standard TAC is expected to generate more turbulence within the flow field along the TAC in comparison with the Slimline TAC’s case… Further, the vorticity strength in the flow field of the standard TAC is expected to be significantly present in comparison to that of the Slimline TAC’s case….”

The significant pressure drop and increased turbulence and vorticity as fluid passes around the B2 tubing anchor can have a material impact on well production. Those parameters are major contributors in the formation of scale, iron sulfide and paraffin, and they play a role in the advent of gas locking. In contrast, the Slimline Tubing Anchor Catcher has been proven to mitigate or minimize those challenges. In fact, by switching from a standard tubing anchor to the Slimline TAC, TechTAC customers have reported numerous benefits, including:
