CTG Energizer Low-Torque Flange Gaskets
What are CTG Energizer gaskets? The CTG Energizer™ is the low-torque flange gasket made by CTG, Inc. (CT Gasket & Polymer Co.) for FRP and plastic piping systems: a 65–75 durometer elastomer body with a seamless sealing face of 100% virgin TFM® or PTFE totally bonded to it. CTG states it needs minimal torque to seal and will not come apart at the inside seam. PE Energy supplies CTG Energizer gaskets in standard sizes from 1/2" to 24", and 26" to 36" by request. Request a quote for any CTG Energizer part number or call +1 (281) 310-0628 / pesales@pe-energy.com. Include the style (NRT or ET), shield (TFM® or PTFE) or elastomer, and quantity. Are CTG Energizer gaskets used in data centers? CTG designed the Energizer for FRP and plastic piping systems, where flanges cannot take high bolt loads. According to CTG, it is widely used in data center cooling plants, where plastic piping (FRP, PVDF, HDPE) with ANSI-style flanged joints carries glycol and water and goes through constant thermal cycling.
