Description and Application: The Plunger lift cover is a very popular solution to insulate plunger lifts. There are a number of different service companies who use our insulated cover because of its practicality. It slides down over the plunger lift to its base, while at the same time allowing for access to the sales line, which comes from the wellhead itself. The Plunger Lift Lubricator Cover has been especially designed for different types and sizes of Plunger Lifts. The cover comes complete with attached straps and is easy to remove and reinstall like all our products. It is compatible with most heat tracing applications.
