DynaRod® Extension (Pony) Rods


DynaRod® extension rod connections are cut to match either threaded or clamped plungers. TPCI’s standard extension rod is available in 303 Stainless Steel coated with Colmonoy. Other pony rods, such as 304 Stainless Steel, 316 Stainless Steel, and 4140 Steel coated in Colmonoy, Tungsten Carbide, Wallex, or exotic metals are also available upon request.


The Triangle Pump Components proprietary manufacturing and assembly process for our Fortis MC ceramic plungers has virtually eliminated the pull-apart problems that customers previously experienced. Triangle Pump Components’ proprietary treatment and manufacturing process allows us to bond dissimilar materials so the joints are stronger than the materials themselves. Our team of experts is committed to making continuous improvements and upholding this tradition of excellence.

Triangle Pump Components’ Fortis MC metal plungers are made of the highest quality carbon and stainless steel on the market today and are coated to improve plunger performance, durability and life expectancy.

Despite our superior manufacturing and assembly processes at Triangle Pump Components, proper plunger installation is critical to maintaining the system’s overall operating efficiency.
