The Industry's Leading Low Torque Sealing Device-Image

Sealing FRP Pipe and Flange Joints?

Use CTG's ET Energizer™, the industry's leading low torque sealing device. The ET Energizer™ utilizes fully-molded, raised sealing ribs which reduce surface contact. A thin PTFE surface is applied to protect the EPDM core from chemical attack. Alternative materials available. Learn how CTG can seal your success!

About CTG:

As an experienced entrepreneur, Don Jackson started CTG in 1984. Established in central Texas near the small town of Rockdale, the company was originally known as Central Texas Gasket.
In 1985, CTG moved to Houston, changed the name to CT Gasket & Polymer, and has grown from a facility of 10,000 square feet to a fully climate controlled 20,000 square foot manufacturing plant located in the heart of Houston industry.

In February of 2004, we celebrated our 20 year anniversary. We also changed our name to CTG to reflect that our customers depend on us for so much more than gaskets.
Now we focus on the future. A future that is unpredictable and ever changing. One thing that will not change is our dedication to offering the highest quality products with prompt deliveries, coupled with our outstanding service.
We look forward to partnering with you to help you achieve your future.


Our customers demand innovation. That's why, despite having the finest low torque gasket available, we set out to make it even better. The new Energizer utilizes a "no-seam" shield providing the thickest protection on the market. For even more demanding applications, we now offer a TFM® shield. Not familiar with the fantastic permeation and compression properties of TFM®? Give us a call and we'll help you choose the best Energizer for your application. For the finest low torque gasket ever created, look no further than CTG.

CTG Inc. manufactures PTFE and elastomeric spring energized seals and sealing systems. Spring Energized Seals can be used in static, reciprocating and slow to medium rotary applications. Unlike many other seals where you must size your seal application around standard size seals,the CTG Spring energized seal can be manufactured to your product. While standard size seals are something we make everyday, we make seals in any size needed. Used as piston, rod, or face seals, the CTG spring energized seal is engineered to meet your exact specifications and design intent.

A doughnut shaped gasket used to prevent the loss of a fluid or a gas, generally made from an elastomer. The O-ring seal assembly usually consists of an elastomer O-ring and a groove (gland). The groove is usually cut into a rigid material to contain the O-ring.

A production run of 15,000 Lexan® stamped gaskets for the medical field followed by a custom layout 7' x 7' square phenolic machine pad with 29 holes - sounds like a normal day in our gasket division. At CTG our specialty is custom applications in every sense.

Rubber bellows are installed on devices with ranges of motion to provide protection from dust and particles. Rubber bellows reduce the frequency of maintenance and increase the life by protecting equipment from contamination.

CTG, Inc. packing sets are light to heavy duty designs that have been in service worldwide for many years in harsh environment applications. The profiles of the packings provide sealing lips which are suited to applications where heavy side loads and high pressure peaks are encountered. Some typical applications for our packings are pistons, hydraulic presses, earth moving equipment, and any other reciprocating and/or rotating heavy duty assembly.

CTG, Inc. specializes in providing cost effective solutions to our customers. With our understanding of the interactions between metals and elastomers and our experience in designing for assembly, we often will suggest bonding rubber to metal substrates. We can work with you on the front-end of your design cycle, so your system performs as intended in the final application. Our experience in working with all metals, including brass, aluminum and steel makes CTG, Inc your bonding solution.

Whether it's an order for our industry leading Energizer low torque gasket, or a part as unique as 90 durometer Butyl, we'll provide you with the molded elastomer part that you require. Even if you just have an idea for a new product, our CNC machining department can make a custom rubber mold to produce the part you want

Lean manufacturing is one more way that American companies are staying a step ahead in efficiency. CTG enables that process by providing CNC machined plastics and metal parts with the speed you need to keep your inventory low.
