Cap King™ Permanent Capillary Tubing Packoff System
For applications requiring a permanent packoff for capillary well injection, Double E offers the Cap King™ in three models; the original 5K Cap King (5,000 psi working pressure, 10,000 psi test pressure); Dual 5K Cap King (5,000 psi working pressure, 10,000 psi test pressure); and the Dual 10K Cap King (10,000 psi working pressure, 15,000 psi test pressure).
All three Cap King models can close on standard diameter tubing sizes. Designed with an integrated hangar, the Cap King offers an economic means of suspending capillary tubing while also retaining well pressure. All models are rated for H2S service.
The 5K Cap King is available with a standard threaded connection. To meet the requirements of many operating companies, Double E also offers a 5K Cap King with a flanged connection. For higher pressure wells, the Dual 10K Cap King offers a dual packoff design for added security, along with a flanged connection.
In addition to the standard line up of Cap King models, Double E also offers the 5K Cap King Tandem Extension. Easily added to a standard 5K Cap King via threaded connection, the 5K Cap King Tandem Extension is designed to provide the protection of a dual-barrier packoff system.
Like all Double E tools, each Cap King model can be modified to meet your specific requirements.
