Mold-on Guide Type
Straight-Vane Mold-on Guide
This is the most popular guide type to centralize sucker rod string and control wear. It is suitable to non-corrosive environment. Depends on the application, this guide is available in 4” (standard) and 7” (XL) in length.
Slant-Vane Mold-on Guide
For corrosive environment with paraffin buildup, the slant-vane mode-on guide can effectively remove it. This guide is available in 4” (standard) length.
Wide-Vane Mold-on Guide
Various designs of wide-vane mold on guide designed to perform under high side loading. Its wearable volume more than doubles that in straight-vane guide and hence ensures its durability. Cross-section of deferent designs of wide-vane mold-on guide are illustrated below.
Field-install Rod Guide
The field-install rod guide provides a cost-effective and flexible solution to guide sucker rod string.
